File Encryption
| Provider | Description |
|---|---|
| VeraCrypt | VeraCrypt is open source cross-platform disk encryption software. You can use it to either encrypt a specific file or directory, or an entire disk or partition. VeraCrypt is incredibly feature-rich, with comprehensive encryption options, yet the GUI makes it easy to use. It has a CLI version, and a portable edition. VeraCrypt is the successor of (the now deprecated) TrueCrypt. |
| Cryptomator | Open source client-side encryption for cloud files- Cryptomator is geared towards using alongside cloud-backup solutions, and hence preserves individual file structure, so that they can be uploaded. It too is easy to use, but has fewer technical customizations for how the data is encrypted, compared with VeraCrypt. Cryptomator works on Windows, Linux and Mac- but also has excellent mobile apps. |
Notable Mentions
CryptSetup is a convinient layer for use on top of dm-crypt. EncFS is a cross-platform file-based encryption module, for use within user local directories. geli is a disk encryption subsystem included with FreeBSD
If you need to create a compressed archive, prior to encrypting your files, then PeaZip is a great little cross-platform open source file archiver utility. It allows you to create, open, and extract RAR TAR ZIP archives.
Encrypted Messaging
Without using a secure app for instant messaging, all your conversations, meta data and more are unprotected. Signal is one of the best options- it's easy, yet also highly secure and privacy-centric.
| Provider | Description |
|---|---|
| Signal | Probably one of the most popular, secure private messaging apps that combines strong encryption (see Signal Protocol) with a simple UI and plenty of features. It's widely used across the world, and easy-to-use, functioning similar to WhatsApp - with instant messaging, read-receipts, support for media attachments and allows for high-quality voice and video calls. It's cross-platform, open-source and totally free. Signal is recommended by Edward Snowden, and is a perfect solution for most users |
| Session | Session is a fork of Signal, however unlike Signal it does not require a mobile number (or any other personal data) to register, instead each user is identified by a public key. It is also decentralized, with servers being run by the community though Loki Net, messages are encrypted and routed through several of these nodes. All communications are E2E encrypted, and there is no meta data. |
| Silence | If you're restricted to only sending SMS/MMS, then Silence makes it easy to encrypt messages between 2 devices. This is important since traditional text messaging is inherently insecure. It's easy-to-use, reliable and secure- but has fallen in popularity, now that internet-based messaging is often faster and more flexible |
| KeyBase | KeyBase allows encrypted real-time chat, group chats, and public and private file sharing. It also lets you cryptographically sign messages, and prove your ownership to other social identities (Twitter, Reddit, GitHub, etc), and send or receive Stella or BitCoin to other users. It's slightly more complex to use than Signal, but it's features extend much further than just a messaging app. Keybase core is built upon some great cryptography features, and it is an excellant choice for managing public keys, signing messages and for group chats. |
| OpenPGP | Provides cryptographic privacy and authentication, PGP is used to encrypt messages sent over existing chat networks (such as email or message boards). Slightly harder to use (than IM apps), slower, but still widely used. Using GnuPG, encrypts messages following the OpenPGP standard, defined by the IETF, proposed in RFC 4880 (originally derived from the PGP software, created by Phil Zimmermann, now owned by Symantec). Note there have been vulnerabilities found in the OpenPGP and S/MIME, defined in EFAIL, so although it still considered secure for general purpose use, it may be better to use an encrypted messaging or email app instead- especially for sensitive communications. |
Other Notable Mentions
Chat Secure and Status, are private, encrypted, open source messenger apps. They are both still in early stages, so weren’t included in the main list. Note that Tor Messengers been removed from the list, since development has halted.
Word of Warning: Proprietary Messaging Platforms
Many messaging apps claim to be secure, but if they are not open source, then this cannot be verified- and they should not be trusted. This applies to Telegram, Threema, Cypher, Wickr, Silent Phone and Viber, to name a few- these apps should not be used to communicate any sensitive data.
P2P Messaging
With Peer-to-Peer networks, there are no central server, so there is nothing that can be raided, shut-down or forced to turn over data. There are P2P networks available that are open source, E2E encrypted, routed through Tor services, totally anonymous and operate without the collection of metadata.
| Provider | Description |
|---|---|
| Matrix + Riot client | Matrix is a decentralized open network for secure communications, with E2E encryption with Olm and Megolm. Along with the Riot client, it supports VOIP + video calling and IM + group chats. Since Matrix has an open specification and Simple pragmatic RESTful HTTP/JSON API it makes it easy to integrates with existing 3rd party IDs to authenticate and discover users, as well as to build apps on top of it. |
| Session + LokiNet client | Loki is an open source set of tools that allow users to transact and communicate anonymously and privately, through a decentralised, encrypted, onion-based network. Session is a desktop and mobile app that uses these private routing protocols to secure messages, media and metadata. |
| Briar | Tor-based Android app for P2P encrypted messaging and forums. Where content is stored securely on your device (not in the cloud). It also allows you to connect directly with nearby contacts, without internet access (using Bluetooth or WiFi). |
| Riochet | Desktop instant messenger, that uses the Tor network to rendezvous with your contacts without revealing your identity, location/ IP or meta data. There are no servers to monitor, censor, or hack so Ricochet is secure, automatic and easy to use. |
| Jami | P2P encrypted chat network with cross-platform GNU client apps. Jami supports audio and video calls, screen sharing, conference hosting and instant messaging. |
| Tox + qTox client | Open source, encrypted, distributed chat network, with clients for desktop and mobile- see supported clients. Clearly documented code and multiple language bindings make it easy for developers to integrate with Tox. |
Other Notable Mentions
Cwtch, BitMessage, RetroShare, Tor Messenger (deprecated), TorChat2 (deprecated)
Encrypted Email
Email is not secure- your messages can be easily intercepted and read. Corporations scan the content of your mail, to build up a profile of you, either to show you targeted ads or to sell onto third-parties. Through the Prism Program, the government also has full access to your emails (if not end-to-end encrypted) - this applies to Gmail, Outlook Mail, Yahoo Mail, GMX, ZoHo, iCloud, AOL and more.
The below email providers are private, end-to-end encrypted (E2EE) and reasonably secure. This should be used in conjunction with good email practices
| Provider | Description |
|---|---|
| ProtonMail | An open-source, end-to-end encrypted anonymous email service. ProtonMail has a modern easy-to-use and customizable UI, as well as fast, secure native mobile apps. ProtonMail has all the features that you'd expect from a modern email service and is based on simplicity without sacrificing security. It has a free plan or a premium option for using custom domains. ProtonMail requires no personally identifiable information for signup, they have a .onion server, for access via Tor, and they accept anonymous payment: BTC and cash (as well as the normal credit card and PayPal). |
| Tutanota | Free and open source email service based in Germany. It has a basic intuitive UI, secure native mobile apps, anonymous signup, and a .onion site. Tutonota has a full-featured free plan or a premium subscription for businesses allowing for custom domains ($12/ month). |
| Mailfence | Mailfence supports OpenPGP so that you can manually exchange encryption keys independently from the Mailfence servers, putting you in full control. Mailfence has a simple UI, similar to that of Outlook, and it comes with bundled with calendar, address book, and files. All mail settings are highly customizable, yet still clear and easy to use. Sign up is not anonymous, since your name, and prior email address is required. There is a fully-featured free plan, or you can pay for premium, and use a custom domain ($2.50/ month, or $7.50/ month for 5 domains), where BitCoin, LiteCoin or credit card is accepted. |
See OpenTechFund- Secure Email for more details.

Self-Hosted Email
If you do not want to trust an email provider with your messages, you can host your own mail server. Without experience, this can be notoriously hard to correctly configure, especially when it comes to security. You may also find that cost, performance and features make it a less attractive option. If you do decide to go down this route, Mail-in-a-box, is an easy to deploy, open source mail server. It aims to promote decentralization, innovation, and privacy on the web, as well as have automated, auditable, and idempotent system configuration. Other ready-to-go self-hosted mail options include Mailu and Mail Cow, both of which are docker containers.
Mail Clients
Email clients are the programs used to interact with the mail server. For hosted email, then the web and mobile clients provided by your email service are usually adequate, and may be the most secure option. For self-hosted email, you will need to install and configure mail clients for web, desktop or mobile. A benefit of using an IMAP client, is that you will always have an offline backup of all email messages (which can then be encrypted and archived), and many applications let you aggregate multiple mailboxes for convenience.
- Desktop - Mozilla Thunderbird is an open source, long-standing and secure desktop email client by Mozilla, for Windows, macOS, and Linux. If you are using ProtonMail, then you can use the ProtonMail Bridge, to sync your emails to either Thunderbird or Microsoft Outlook. In terms of security, the disadvantage, is that most desktop clients do not support 2FA, so it is important to keep your computer secured, however they are not vulnerable to the common browser attacks, that a web client would be. See also eM Clientm which is a reputable but proprietary paid desktop client for Windows and Mac OS.
- Web - If you are self-hosting your mail server, you will probably want a web-based email client. RainLoop and RoundCube are both good open source options.
- Mobile - the most secure option is usually to use the app provided by your mail provider. If your mail server is self-hosted, then consider FairMail which is a fully featured, open source, privacy oriented email app for Android. There is also pretty Easy privacy p≡p, which has OpenPGP built in, and K-9 Mail, (which has been around almost as long as Android!), has a solid reputation for privacy and security features.
TorBirdy is a Thunderbird addon, that configures it to make connections over the Tor network
It is important to keep the device/ server running your mail client secure.

Anonymous Mail Forwarding
Revealing your real email address online can put you at risk. Email aliasing allows messages to be sent to [anything]@my-domain.com and still land in your primary inbox. This protects your real email address from being revealed. Aliases are generated automatically, the first time they are used. This approach lets you identify which provider leaked your email address, and block an alias with 1-click.
| Provider | Description |
|---|---|
| Anonaddy | An open source anonymous email forwarding service, allowing you to create unlimited email aliases. Has a free plan. |
| 33Mail | A long-standing aliasing service. As well as receiving, 33Mail also lets you reply to forwarded addresses anonymously. Free plan, as well as Premium plan ($1/ month) if you'd like to use a custom domain |
| SimpleLogin | Fully open source (view on GitHub) allias service with many additional features. Can be self-hosted, or the managed version has a free plan, as well as hosted premium option ($2.99/ month) for using custom domains |
| Firefox Private Relay | Developed and managed by Mozilla, Relay is a Firefox addon, that lets you make an email alias with 1 click, and have all messages forwarded onto your personal email. Relay is totally free to use, and very accessible to less experienced users, but also open source, and able to me self-hosted for advanced usage |
| ForwardEmail | Simple open source catch-all email forwarding service. Easy to self-host (see on GitHub), or the hosted version has a free plan as well as a ($3/month) premium plan |
| ProtonMail Visionary | If you already have ProtonMail's Visionary package, then an implementation of this feature is available. Very secure, however not the most price-effective (€30/month), and does not include dashboard |
Alternatively you could host your own catch-all email service. Mailu can be configured to accept wildcards, or for Microsoft Exchange see exchange-catchall
Browsers
| Provider | Description |
|---|---|
| Brave Browser | Brave Browser, currently one of the most popular private browsers- it provides speed, security, and privacy by blocking trackers with a clean, yet fully-featured UI. It also pays you in BAT tokens for using it. Brave also has Tor built-in, when you open up a private tab/ window. |
| FireFox | Significantly more private, and offers some nifty privacy features than Chrome, Internet Explorer and Safari. After installing, there are a couple of small tweaks you will need to make, in order to secure Firefox. You can follow one of these guides by: Restore Privacy, Security Gladiators or 12Bytes |
| Bromite | Bromite is Chromium (Chrome without Google) plus ad blocking and enhanced privacy. It provides a no-clutter browsing experience without privacy-invasive features- it's lightweight and minimal |
| Tor Browser | Tor provides an extra layer of anonymity, by encrypting each of your requests, then routing it through several nodes, making it near-impossible for you to be tracked by your ISP/ provider. It does make every-day browsing a little slower, and some sites may not work correctly. As with everything there are trade-offs |
Notable Mentions

Word of Warning
Browsers are inherently insecure, be careful when uploading, or entering personal details.
Virtual Private Networks
VPNs are good for getting round censorship, increasing protection on public WiFi, obscuring your IP address, and reducing what data your ISP can log. But for the best anonymity, you should use Tor. VPNs do not mean you are magically protected, or anonymous (see below).
| Provider | Description |
|---|---|
| Mullvad | Mullvad is one of the best for privacy, they have a totally anonymous sign up process, you don't need to provide any details at all, you can choose to pay anonymously too (with Monero, BTC or cash) |
| ProtonVPN | From the creators of ProtonMail, ProtonVPN has a solid reputation. They have a full suit of user-friendly native mobile and desktop apps. ProtonVPN is one of the few "trustworthy" providers that also offer a free plan |
Other VPN Options
AirVPN has advanced features and is highly customizable, WindScribe also has a ton of features as well as anonymous sign up, yet is very easy to use for all audiences with excellent cross-platform apps. See also: Perfect Privacy -- TorGuard -- IVPN -- PureVPN -- NordVPN -- SwitchVPN -- Safer VPN -- VirtualShield -- Private Internet Access -- VPN.ac -- VyperVPN
Full VPN Comparison: thatoneprivacysite.net.
Word of Warning
- A VPN does not make you anonymous- it merely changes your public IP address to that of your VPN provider, instead of your ISP. Your browsing session can still be linked back to your real identity either through your system details (such as user agent, screen resolution even typing patterns), cookies/ session storage, or by the identifiable data that you enter. Read more about fingerprinting
- Logging- If you choose to use a VPN because you do not agree with your ISP logging your full browsing history, then it is important to keep in mind that your VPN provider can see (and mess with) all your traffic. Many VPNs claim not to keep logs, but you cannot be certain of this (VPN leaks). See this article for more
- IP Leaks- If configured incorrectly, your IP may be exposed through a DNS leak. This usually happens when your system is unknowingly accessing default DNS servers rather than the anonymous DNS servers assigned by an anonymity network or VPN. Read more: What is a DNS leak, DNS Leak Test, How to Fix a DNS Leak
- Stealth - It will be visible to your adversary that you are using a VPN (usually from the IP address), but other system and browser data, can still reveal information about you and your device (such as your local time-zone, indicating which region you are operating from)
- Many reviews are sponsored, and hence biased. Do your own research, or go with one of the above options
- Using Tor (or another Mix Network) may be a better option for anonimity
Considerations
While choosing a VPN, consider the following: Logging policy (logs are bad), Jurisdiction (avoid 5-eyes), Number of servers, availability and average load. Payment method (anonymous methods such as BTC, Monero or cash are better), Leak protection (1st-party DNS servers = good, and check if IPv6 is supported), protocols (OpenVPN and WireGuard = good). Finally, usability of their apps, user reviews and download speeds.
Self-Hosted VPN
If you don't trust a VPN provider not to keep logs, then you could self-host your own VPN. This gives you you total control, but at the cost of anonymity (since your cloud provider, will require your billing info). See Streisand, to learn more, and get started with running a VPN. Digital Ocean provides flexible, secure and easy Linux VMs, (from $0.007/hour or $5/month), this guide explains how to set up VPN on: CentOS 7 or Ubuntu 18.4+. See more about configuring OpenVPN or IKEv2. Alternatively, here is a 1-click install scriptfor on Digital Ocean, by Carl Friess.
Self-Hosted Network Security
Fun little projects that you can run on a Raspberry Pi, or other low-powered computer. In order to help detect and prevent threats, monitor network and filter content
| Provider | Description |
|---|---|
| Pi-Hole | Network-level advertisement and Internet tracker blocking application which acts as a DNS sinkhole. Pi-Hole can significantly speed up your internet, remove ads and block malware. It comes with a nice web interface and a mobile app with monitoring features, it's open source, easy to install and very widely used |

Mix Networks
Mix networks are routing protocols, that create hard-to-trace communications, by encrypting and routing traffic through a series of nodes. They help keep you anonymous online, and unlike VPNs -there are no logs
| Provider | Description |
|---|---|
| Tor | Tor provides robust anonymity, allowing you to defend against surveillance, circumvent censorship and reduce tracking. It blocks trackers, resists fingerprinting and implements multi-layered encryption by default, meaning you can browse freely. Tor also allows access to OnionLand: hidden services |
| I2P | I2P offers great generic transports, it is well geared towards accessing hidden services, and has a couple of technical benefits over Tor: P2P friendly with unidirectional short-lived tunnels, it is packet-switched (instead of circuit-switched) with TCP and UDP, and continuously profiles peers, in order to select the best performing ones. I2P is less mature, but fully-distributed and self-organising, it's smaller size means that it hasn't yet been blocked or DOSed much |
| Freenet | Freenet is easy to setup, provides excellent friend To Friend Sharing vs I2P, and is great for publishing content anonymously. It's quite large in size, and very slow so not the best choice for casual browsing |
Tor, I2P and Freenet are all anonymity networks- but they work very differently and each is good for specific purposes. So a good and viable solution would be to use all of them, for different tasks. You can read more about how I2P compares to Tor, here
Notable Mentions
Panoramix is a European project, aiming to use mix-networks to provide anonymity. Nym uses Blockchain to reward node operators in order to keep the network sustainable.
Word of Warning
To provide low-latency browsing, Tor does not mix packets or generate cover traffic. If an adversary is powerful enough, theoretically he could either observe the entire network, or just the victims entry and exit nodes. It's worth mentioning, that even though your ISP can not see what you are doing, they will be able determine that you are using a mix net, to hide this- a VPN could be used. If you are doing anything which could put you at risk, then good OpSec is essential, as the authorities have traced criminals through the Tor network before, and made arrests. Don't let Tor provide a possible false sense of security- be aware of information leaks through DNS or other programs, and Tor-supported browsers may might lag behind their upstream forks, allowing for unpatched issues. See #19
Note: The Tor network is run by the community. If you benefit from using it and would like to help sustain uncensored internet access for all, consider running a Tor relay.
Proxies
A proxy acts as a gateway between you and the internet, it can be used to act as a firewall or web filter, improves privacy and can also be used to provide shared network connections and cache data to speed up common requests. Never use a free proxy.
| Provider | Description |
|---|---|
| ShadowSocks | Secure socks5 proxy, designed to protect your Internet traffic. Open source, superfast, cross-platform and easy to deploy, see GitHub repo |
| Privoxy | Non-caching web proxy with advanced filtering capabilities for enhancing privacy, modifying web page data and HTTP headers, controlling access, and removing ads and other obnoxious Internet junk |
Notable Mentions
V2ray-core is a platform for building proxies to bypass network restrictions and protect your privacy. See more
Word of Warning
Malicious Proxies are all too common. Always use open source software, host it yourself or pay for a reputable cloud service. Never use a free proxy; it can monitor your connection, steal cookies and contain malware. VPNs are a better option, better still- use the Tor network.
DNS
Without using a secure, privacy-centric DNS all your web requests can be seen in the clear. You should configure your DNS queries to be managed by a service that respects privacy and supports DNS-over-TLS, DNS-over-HTTPS or DNSCrypt.
| Provider | Description |
|---|---|
| CloudFlare | One of the most performant options, Cloudflare's DNS supports DoH and DoT, and has a Tor implementation, providing world-class protection. They have native cross-platform apps, for easy set-up. |
| AdGuard | Open-source DNS provider, specialising in the blocking of ads, trackers and malicious domains. They have been independently audited and do not keep logs |
| SecureDNS | An open source DNS provider, with built-in ad block and additional privacy features. Supports DoH, DoT and DNSCrypt. It is not as performant as some of the bigger players, but still a good option in terms of security |
| NextDNS | An ad-blocking, privacy-protecting, censorship-bypassing DNS. Also comes with analytics, and the ability to shield kids from adult content |
See also this Full List of Public DoH Servers, you can then check the performance of your chosen server with DNSPerf. To read more about choosing secure DNS servers, see this article, and this article.
DNS Protocols
DNS-over-TLS was proposed in RTC-7858 by the IETF, then 2 years later, the DNS-over-HTTPS specification was outlined in RFC8484 in October '18. DNSCrypt, is a protocol that authenticates communications between a DNS client and a DNS resolver. It prevents DNS spoofing, through using cryptographic signatures to verify that responses originate from the chosen DNS resolver, and haven’t been tampered with. DNSCrypt is a well battle-tested protocol, that has been in use since 2013, and is still widely used.
Notable Mentions
- Quad9 is a well-funded, performant DNS with a strong focus on privacy and security and easy set-up, however questions have been raised about the motivation of some of the financial backers.
- BlahDNS (Japan, Finland or Germany) is an excellent security-focused DNS
- OpenNIC, NixNet DNS and UncensoredDNS are open source and democratic, privacy-focused DNS
- Unbound is a validating, recursive, caching DNS resolver, designed to be fast and lean. Incorporates modern features and based on open standards
- Clean Browsing, is a good option for protecting kids, they offer comprehensive DNS-based Content Filtering
Word of Warning
Using an encrypted DNS resolver will not make you anonymous, it just makes it harder for third-partied to discover your domain history. If you are using a VPN, take a DNS leak test, to ensure that some requests are not being exposed.
Firewalls
A firewall is a program which monitors the incoming and outgoing traffic on your network, and blocks requests based on rules set during its configuration. Properly configured, a firewall can help protect against attempts to remotely access your computer, as well as control which applications can access which IPs.
| Provider | Description |

Word of Warning
There are different types of firewalls, that are used in different circumstances. This does not omit the need to configure your operating systems defences. Follow these instructions to enable your firewall in Windows, Mac OS, Ubuntu and other Linux ditros. Even when properly configured, having a firewall enabled does not guarantee bad network traffic can not get through and especially during boot if you don't have root privileges.
Router Firmware
Installing a custom firmware on your Wi-Fi router gives you greater control over security, privacy and perfromance
| Provider | Description |
|---|---|
| OpenWRT | Plenty of scope for customization and a ton of supported addons. Stateful firewall, NAT, and dynamically-configured port forwarding protocols (UPnP, NAT-PMP + upnpd, etc), Load balancing, IP tunneling, IPv4 & IPv6 support |

SpiderOak, Tresorit and Resilio are good enterprise solutions, all with solid encryption baked-in
FileRun and Pydio are self-hosted file explorers, with cross-platform sync capabilities.
Word of Warning
You should always ensure that any data stored in the cloud is encrypted. If you are hosting your own server, then take the necessary precautions to secure the server. For hosted solutions- use a strong password, keep your credentials safe and enable 2FA.
Encrypted Cloud Storage
Backing up important files is essential, and keeping an off-site copy is recommended. But many free providers do not respect your privacy, and are not secure enough for sensitive documents. Avoid free mainstream providers, such as Google Drive, cloud, Microsoft Overdrive, Dropbox.
It is recommended to encrypt files on your client machine, before syncing to the cloud. Cryptomator is a cross-platform, open source encryption app, designed for just this.

Notable Mentions
An alternative option, is to use a cloud computing provider, and implement the syncing functionality yourself, and encrypt data locally before uploading it- this may work out cheaper in some situations. You could also run a local server that you physically own at a secondary location, that would mitigate the need to trust a third party cloud provider. Note that some knowledge in securing networks is required.

Social Networks
Over the past decade, social networks have revolutionized the way we communicate and bought the world closer together- but it came at the cost of our privacy. Social networks are built on the principle of sharing- but you, the user should be able to choose with whom you share what, and that is what the following sites aim to do.

Word of Warning
Without moderation, some of these platforms accommodate video creators, who content may not be appropriate for all audiences
YouTube Proxies
The content on many of the smaller video sites, often just doesn't compare to YouTube. So another alternative, is to access YouTube through a proxy client, which reduces what Google can track).
- Good options are: Invidio (web), FreeTube (Windows, Mac OS, Linux), NewPipe (Android), YouTube++ (iOS)

Of course you could also host your blog on your own server, using a standard open source blog platform, such as Ghost and configure it to disable all trackers, ads and analytics.
News Readers and Aggregation
| Provider | Description |
|---|---|
| Tiny RSS | A free and open source web-based news feed (RSS/Atom) reader and aggregator |
| RSSOwl | A desktop-based RSS reader, with powerful organisation features |
| Feedly | A more premium option. Feedly displays news from your selected sources in an easy-to-digest clean and modern interface. It works with more than just RSS feeds, since it is well integrated with many major news outlets. It does not manipulate the stories you see, and is mostly open source |
Notable Mentions
For iPhone users in the US, Tonic is a great little app that provides you with a selection of personalized new stories and articles daily. It is possible to us Reddit anonymously too- you can use throwaway accounts for posting.
Word of Warning
News reader apps don't have a good reputation when it comes to protecting users privacy, and often display biased content. Many have revenue models based on making recommendations, with the aim of trying to get you to click on sponsored articles- and for that a lot of data needs to have been collected about you, your habits, interests and routines.
Cryptocurrencies
| Provider | Description |
|---|---|
| Monero | One of the most private cryptocurrencies, since no meta data is available (not even the transaction amount). It uses complex on-chain cryptographic methods such as Ring signatures, RingCT, Kovri, and Stealth addresses all of which help protect the privacy of users |
| ZCash | Uses zero-knowledge proofs to protect privacy cryptographic technique, that allows two users to transact without ever revealing their true identity or address. The Zcash blockchain doesn't record any send or receive addresses |
It is still possible to use currencies that have a public ledger 'privately', but you will need to take great care not to cause any transactions to be linked with your identity or activity. For example, avoid exchanges that require KYC, and consider using a service such as Local Bitcoins. If you use a BitCoin ATM, then take care to not be physically tracked (CCTV, phone location, card payments etc)
Notable Mentions
Other privacy-focused cryptocurrencies include: PIVX, Bitcoin Private and Verge.
Word of Warning
Not all cryptocurrencies are anonymous, and without using a privacy-focused coin, a record of your transaction will live on a publicly available distributed ledger, forever. If you send of receive multiple payments, ensure you switch up addresses or use a mixer, to make it harder for anyone trying to trace your transactions. Store private keys somewhere safe, but offline and preferably cold.
Note: Cryptocurrency prices can go down. Storing any wealth in crypto may result in losses. If you are new to digital currencies- do your research first, don't invest more than you can afford, and be very weary of scams and cryptocurrency-related malware.
Virtual Credit Cards
Virtual cards generated provide an extra layer of security, improve privacy and help protect from fraud. Most providers have additional features, such as single-use cards (that cannot be charged more than once), card limits (so you can be sure you won't be charged more than you expected) and other security controls.
| Provider | Description |
|---|---|
| Privacy.com | Privacy.com has a good reputation, and is the largest virtual card provider in the US. Unlike other providers, it is free for personal use (up to 12 cards per month) with no fees, apps and support is good. There is a premium is plan for $10/month, with 1% cashback 36 cards/ month |
| Revolut Premium | Revoult is more of a digital bank account, and identity checks are required to sign up. Virtual careds only availible on Premium/ Metal accounts, which start at $7/month. |
| MySudo | Much more than just virtual cards, MySudo is a platform for creating compartmentalised identities, each with their own virtual cards, virtual phone numbers, virtual email addresses, messaging, private browsing and more. There is a free plan for up to 3 identities, and premium plans start at $0.99/ month |
| Blur | Blur by Abine has virtual card functinality, |
PayLasso, JoinToken, EntroPay are now discontinued
Other Payment Methods
| Provider | Description |
|---|---|
| Cash | Actual physical cash is still the most private option, with no chance of leaving any transactional records |
| Gift Cards | Gift cards can be purchased for cash in many convenience stores, and redeemed online for goods or services. Try to avoid CCTV as best as possible. |
| Pre-paid Cards | Similarly to gift cards, buying a pre-paid card for cash, can enable you to purchase goods and services in stores that only accept card payments. |
Paying for goods and services is a good example of where privacy and security conflict; the most secure option would be to pay with credit card, since most providers include comprehensive fraud protection, whereas the most private option would be to pay using crypto currency or cash, since neither can be easily tied back to your identity.
Word of Warning
Note that credit card providers heavily track transaction metadata, which build up a detailed picture of each persons spending habits. This is done both to provide improved fraud alerts, but also because the data is extremely valuable and is often 'anonymized' and sold to 3rd parties. Hence your privacy is degraded if these cards are used for daily transactions
Budgeting Tools
| Provider | Description |
|---|---|
| Firefly III (Self-hosted) | A free and open source personal finance manager. Firefly III has all essential features, a clean and clear UI and is easy to set up and use (see live demo). It's backed by a strong community, and is regularly updated with new features, improvements and fixes. There is also a hass.io addon, and it works nicely with Home Assistant. Note: Since it is self-hosted, you will need to ensure that your server (either local or remote) is correctly configured for security. |

Mobile Operating Systems
If you are an Android user, your device has Google built-in at it's core. Google tracks you, collecting a wealth of information, and logging your every move. A custom ROM, is an open source, usually Google-free mobile OS that can be flashed to your device.
| Provider | Description |
|---|---|
| LineageOS | A free and open-source operating system for various devices, based on the Android mobile platform- Lineage is light-weight, well maintained, supports a wide range of devices, and comes bundled with Privacy Guard |
| GrapheneOS | GrapheneOS is an open source privacy and security focused mobile OS with Android app compatibility. Developed by the team behind CoperheadOS. Graphene is a young project, and currently only supports Pixel devices, partially due to their strong hardware security |
Other Notable Mentions
Replicant OS is a fully-featured distro, with an emphasis on freedom, privacy and security. MmniRom, Recursion Remix, and Paranoid Android are also popular options. Alternativley, Ubuntu Touch is a Linux (Ubuntu)- based OS. It is secure by design and runs on almost any device, - but it does fall short when it comes to the app store.
To install apps on the Play Store without using the Play Store app see Aurora Store. For Google Play Service see MicroG
Word of Warning
It is not recommended to root, or flash your device with a custom ROM if you are not an advanced user. There are risks involved
- Although the above ROMs omit Google, they do open up other security issues: Without DM-verity on the system partition, the file system could be tampered with, and no verified boot stack, the kernel/initramfs also could be edited. You should understand the risks, before proceeding to flash a custom ROM to your device
- You will need to rely on updates from the community, which could be slower to be released- this may be an issue for a time-urgent, security-critical patch
- It is also possible to brick your device, through interrupted install or bad software
- Finally, rooting and flashing your device, will void your warranty
PC Operating Systems
Windows 10 has many features that violate your privacy. Microsoft and Apple are able to collect all your data (including, but not limited to: keystrokes, searches and mic input, calendar data, music, photos, credit card information and purchases, identity, passwords, contacts, conversations and location data). Microsoft Windows is also more susceptible to malware and viruses, than alternative systems.
| Provider | Description |
|---|---|
| Qubes OS (containerized apps) | Open-source security-oriented operating system for single-user desktop computing. It uses virtualisation, to run each application in it's own compartment to avoid data being leaked. It features Split GPG, U2F Proxy, and Whonix integration. Qubes makes is easy to create disposable VMs which are spawned quickly and destroyed when closed. Qubes is recommended by Edward Snowden |
| Whonix (VM) | Whonix is an anonymous operating system, which can run in a VM, inside your current OS. It is the best way to use Tor, and provides very strong protection for your IP address. It comes bundled with other features too: Keystroke Anonymization, Time Attack Defences, Stream Isolation, Kernel Self Protection Settings and an Advanced Firewall. Open source, well audited, and with a strong community- Whonix is based on Debian, KickSecure and Tor |
| Tails (live) | Tails is a live operating system (so you boot into it from a USB, instead of installing). It preserves your privacy and anonymity through having no persistent memory/ leaving no trace on the computer. Tails has Tor built-in system-wide, and uses state-of-the-art cryptographic tools to encrypt your files, emails and instant messaging. Open source, and built on top of Debian. Tails is simple to stup, configure and use |
| Parrot (security) | Parrot Linux, is a full Debian-based operating system, that is geared towards security, privacy and development. It is fully-featured yet light-weight, very open. There are 3 edditions: General Purpose, Security and Forensic. The Secure distribution includes its own sandbox system obtained with the combination of Firejail and AppArmor with custom security profiles. While the Forensics Edition is bundled with a comprehensive suit of security/ pen-testing tools, similar to Kali and Black Arch |
| Discreete Linux (offline) | Aimed at journalists, activists and whistle-blowers, Discreete Linux is similar to Tails, in that it is booted live from external media, and leaves no/ minimal trace on the system. The aim of the project, was to provide all required cryptographic tools offline, to protect against Trojan-based surveillance |
| Alpine Linux | Alpine is a security-oriented, lightweight distro based on musl libc and busybox. It compiles all user-space binaries as position-independent executables with stack-smashing protection. Install and setup may be quite complex for some new users |
Notable Mentions
Subgraph OS, PureOS, Kali (defensive security), BlackArch (defensive security), Kodachi, IprediaOS (obsolete), Fedora CoreOS
General Purpose Linux Distros
If you do not want to use a specalist security-based distro, or you are new to Unix- then just switching to any well-maintained Linux distro, is going to be significantly more secure and private than Windows or Mac OS. Since it is open source, major distros are constantly being audited by members of the community. Linux does not give users admin rights by default- this makes is much less likley that your system could become infected with malware. And of course, there is no proprietary Microsoft or Apple software constantly monitoring everything you do.
Some good distros to consider would be: Fedora, Debian, or Arch- all of which have a large community behind them. Manjaro (based of Arch) is a good option, with a simple install process, used by new comers, and expers alike. See comparison.
BSD systems arguably have far superior network stacks. OpenBSD is designed for maximum security — not just with its features, but with its implementation practices. It’s a commonly used OS by banks and critical systems. FreeBSD is more popular, and aims for high performance and ease of use.
Improve the Security and Privacy of your current OS
If you have chosen to stick with your current OS, there are a couple of things you can do to improve security, see: Windows 10 security guide, Mac OS security guide or Linux security guide.
Linux Defences
| Provider | Description |
|---|---|
| Firejail | Firejail is a SUID sandbox program that reduces the risk of security breaches by restricting the running environment of untrusted applications using Linux namespaces and seccomp-bpf. Written in C, virtually no dependencies, runs on any modern Linux system, with no daemon running in the background, no complicated configuration, and it's super lightweight and super secure, since all actions are implemented by the kernel. It includes security profiles for over 800 common Linux applications. FireJail is recommended for running any app that may potential pose some kind of risk, such as torrenting through Transmission, browsing the web, opening downloaded attachments |
Windows Defences
| Provider | Description |
|---|---|
| HardenTools | A utility that disables a number of risky Windows features. These "features" are exposed by the OS and primary consumer applications, and very commonly abused by attackers, to execute malicious code on a victim's computer. So this tool just reduces the attack surface by disabling the low-hanging fruit |
| ShutUp10 | A portable app that lets you disable core Windows features (such as Cortana, Edge) and control which data is passed to Microsoft. (Note: Free, but not open source) |
| GhostPress | Anti low-level keylogger: Provides full system-wide key press protection, and target window screenshot protection |
| KeyScrambler | Provides protection against software keyloggers. Encrypts keypresses at driver level, and decrypts at application level, to protect against common keyloggers- read more about how it works. Developed by Qian Wang |
| SafeKeys V3.0 | Portable virtual keyboard. Useful for protecting from keyloggers when using a public computer, as it can run of a USB with no administrative permissions |
| RKill | Useful utility, that attempts to terminate known malware processes, so that your normal security software can then run and clean your computer of infections |
| IIS Crypto | A utility for configuring encryption protocols, cyphers, hashing methods, and key exchanges for Windows components. Useful for sysadmins on Windows Server |
| NetLimiter | Internet traffic control and monitoring tool |
| Sticky-Keys-Slayer | Scans for accessibility tools backdoors via RDP |
| SigCheck | A CLI utility that shows file version number, timestamp information, and digital signature details. It's useful to audit a Windows host's root certificate store against Microsoft's Certificate Trust List (CTL), and lets you perform VirusTotal lookups |
| Windows Secure Baseline | Group Policy objects, compliance checks, and configuration tools that provide an automated and flexible approach for securely deploying and maintaining the latest releases of Windows 10 |
| ScreenWings | Blocks malicious background applications from taking screenshots |
| CamWings | Blocks unauthorized webcam access |
Word of Warning
Create a system restore point, before making any significant changes to your OS (such as disabling core features). From a security and privacy perspective, Linux may be a better option. Many of the above tools are not necessary or suitable for beginners, and can cause your system to break.

Mac OS Defences
| Provider | Description |
|---|---|
| LuLu | Free, open source macOS firewall. It aims to block unknown outgoing connections, unless explicitly approved by the user |
| Stronghold | Easily configure macOS security settings from the terminal |
| Fortress | Kernel-level, OS-level, and client-level security for macOS. With a Firewall, Blackhole, and Privatizing Proxy for Trackers, Attackers, Malware, Adware, and Spammers; with On-Demand and On-Access Anti-Virus Scanning |
Anti-Virus and Malware Prevention
| Provider | Description |
|---|---|
| CalmAV | An open source cross-platform antivirus engine for detecting viruses, malware & other malicious threats. It is versatile, performant and very effective |
| Windows Spy Blocker | Capture and interprets network traffic based on a set of rules, and depending on the interactions certain assignments are blocked. Open source, written in Go and delivered as a single executable |
| Cylance | Takes more of an application whitelisting approach, where it generates the list of trusted software through machine learning. So instead of identifying bad software to block, it identifies good software instead, and blocks the rest by default |
Notable Mentions
Your operating system's built-in protection is probably adequate for detecting 99% of threats. Installing additional software can introduce more vulnerabilities, so downloading AV may actually degrade your privacy and increase your attack surface.
Windows, by default is not very private. There are several packages that can be used to quickly tweak privacy settings. Such as Simple Wall, priv10, Fix-Windows-Privacy and W10 Privacy (see Video Tutorial). Use at your own risk, disabling some OS features can cause unintended consequences. See also, this Windows 10 Privacy Guide for manual steps.
For 1-off malware scans, MalwareBytes is portable and very effective- thorough in identifying threats, with minimum data collection. However it is not open source.
Word of Warning
Many anti virus products have a history of introducing vulnerabilities themselves, and several of them seriously degrade the performance of your computer, as well as decrease your privacy. Never use a free anti-virus, and never trust the companies that offer free solutions, even if you pay for the premium package. This includes (but not limited to) Avast, AVG, McAfee and Kasperky. For AV to be effective, it needs intermate access to all areas of your PC, so it is important to go with a trusted vendor, and monitor it's activity closley. Read more about why you shouldn't use Anti-Spy Tools, on Windows.
Home Automation
If you have smart devices within your home, you should consider running the automation locally, rather than using a cloud service. This will reduce the amount of exploits you could potentially be vulnerable to. It is also important to have network monitoring and firewalls enabled, to ensure suspicious activity is flagged or blocked. The following projects will make controlling and monitoring IoT devices within your home easier, safer and more private.
| Provider | Description |
|---|---|
| Home Assistant | Open source home automation that puts local control and privacy first- 1500+ integrations. Runs well on a Raspberry Pi, accessible though a web interface and CLI, as well as several controller apps (such as HassKit and the official Home Assistant App) |
| OpenHAB | A vendor and technology agnostic open source automation software for your home, with 2000+ supported devices and addons. Works well on a Raspberry Pi, or low-powerd home server, and again there are some great apps for, such as the official OpenHabb App and the HomeHabit wall dashboard |
| Domoticz | Another home automation system, Domoticz is more geared towards connecting and monitoring sensors within your space. Allows you to monitor your environment without anyone but you having access to the data |
| Node-RED | Node-RED is a programming tool for wiring together hardware devices, APIs and online services, it provides a browser-based editor that makes it easy to build flows with a wide range of supported nodes, and it is easy to deploy locally in your network |
Notable Mentions
For creating dashboard from IoT devices, see ThingsBoard. Another home automation tool is FHEM, which has been around for a while and needs a bit more work to get up and running, but is still a popular option.
Word of Warning
IoT smart home devices can open you up to many security risks and exploits. It is really important that you configure them correctly, setting strong unique passwords, turn off data sharing, and if possible restrict internet access so devices can only communicate within your local network. See Smart Home Security Checklist for more tips.
AI Voice Assistants
Google Assistant, Alexa and Siri don't have the best reputation when it comes to protecting consumers privacy, there have been many recent breaches. For that reason it is recommended not to have these devices in your house. The following are open source AI voice assistants, that aim to provide a human voice interface while also protecting your privacy and security
| Provider | Description |
|---|---|
| Mycroft | An open source privacy-respecting AI platform, that runs on many platforms (Raspberry Pi, desktop, or dedicated Mycroft device). It is in active development, with thorough documentation and a broad range of available skills, but also Mycroft makes it really easy to develop new skills |
| Kalliope | An open source, modular always-on voice controlled personal assistant designed for home automation. It runs well on Raspberry Pi, Debian or Ubuntu and is easy to program with simple YAML-based skills, but does not have a wide library of pre-built add-ons |
Notable Mentions
If you choose to continue using Google Home/ Alexa, then check out Project Alias. It's a small app that runs on a Pi, and gives you more control over your smart assistants, for both customisation and privacy.
For a desktop-based assistant, see Dragonfire for Ubuntu, and Jarvis for MacOS. LinTO, Jovo and Snips are private-by-design voice assistant frameworks that can be built on by developers, or used by enterprises. Jasper, Stephanie and Hey Athena are Python-based voice assistant, but neither is under active development anymore. See also OpenAssistant.
Word of Warning
If you are building your own assistant, you may want to consider a hardware-switch for disabling the microphone. Keep tabs on issues and check the code, to ensure you are happy with how it works, from a privacy perspective.

Final Notes
Conclusion
Many coporations put profit before people, collecting data and exploiting privacy. They claim to be secure but without being open source it can't be verified, until there's been a breach and it's too late. Switching to privacy-respecting open source software will drastically help improving your security, privacy and anonymity online.
However, that's not all you need to do. It is also important to : use strong and unique passwords, 2-factor authentication, adopt good networking practices and be mindful of data that are collected when browsing the web. You can see the full personal security checklist for more tips to stay safe.
Important Considerations
Compartmentalise
No piece of software is truly secure or private. Further to this, software can only as secure as the system it is running on. Vulnerabilities are being discovered and patched all the time, so you much keep your system up-to-date. Breaches occur regularly, so compartmentalise your data to minimise damage. It's not just about choosing secure software, you must also follow good security practices.
Attack Surface
It is a good idea to keep your trusted software base small, to reduce potential attack surface. At the same time trusting a single application for too many tasks could be a weakness in your system. So you will need to judge the situation according to your threat model, and carefully plan which software and applications you trust with each segment of your data.
Convenience Vs Security
There is often a trade-off between convenience and security. Construct a threat model, and choose a balance that is right for you. In a similar way in some situations there is privacy and security conflict (e.g. Find My Phone is great for security, but terrible for privacy, and anonymous payments may be good for privacy but less secure than insured fiat currency). Again it is about assessing your situation, understanding the risks and making an informed decision.
Hosted Vs Self-Hosted Considerations
When using a hosted or managed application that is open-source software- there is often no easyily way to tell if the version running is the same as that of the published source code (even published signatures can be faked). There is always the possibility that additional backdoors may have been knowingly or unknowingly implemented in the running instance. One way round this is to self-host software yourself. When self-hosting you will then know for sure which code is running, however you will also be responsible for the managing security of the server, and so may not be recommended for beginners.
Open Source Software Considerations
Open source software has long had a reputation of being more secure than its closed source counterparts. Since bugs are raised transparently, fixed quickly, the code can be checked by experts in the community and there is usually little or no data collection or analytics. That being said, there is no piece of software that it totally bug free, and hence never truly secure or private. Being open source, is in no way a guarantee that something is safe. There is no shortage of poorly-written, obsolete or sometimes plain malicious open source projects on the internet.
Proprietary Software Considerations
When using a hosted or proprietary solution- always check the privacy policy, research the reputation of the organisation, and be weary about which data you trust them with. Where possible choose open source software for security-critical situations.
Maintenance
When selecting a new application, ensure it is still being regularly maintained, as this will allow for recently discovered security issues to be addressed. Software in an alpha or beta phase, may not only be buggy or lacking in features, but it could have critical vulnerabilities open to exploit. Similarly, applications that are no longer being actively maintained may pose a security risk. When using a forked application, or software that is based on an upstream code base, be aware that it may receive security-critical patches and updates at a slightly later date than the original application.
This List: Disclaimer
This list contains packages that range from entry-level to advanced, a lot of the software here will not be appropriate for all audiences. It is in no way a definitive list of secure applications, and aims only to be a guide, a collection of software and services that myself and others have used, and would recommend. There will always be new vulnerabilities discovered or introduced, bugs and poorly configured systems. It is up to you to do your research, and decide where and how your data are managed.
If you find something on this list that should no longer be deemed secure, please raise an issue. In the same way if you know of something that is missing, or would like to make an edit, the pull requests are welcome, and are much appreiciated!
