<p>In most cases, most of your traffic is already encrypted! Over 98% of the top 3000 websites offer <strong>HTTPS</strong>, meaning your non-DNS traffic is safe regardless of using a VPN. It is incredibly rare for applications that handle personal data to not support HTTPS in 2019, especially with services like Let's Encrypt offering free HTTPS certificates to any website operator.</p>
<p>Even if a site you visit doesn't support HTTPS, a VPN will not protect you, because a VPN cannot magically encrypt the traffic between the VPN's servers and the website's servers. Installing an extension like <a href="https://www.eff.org/https-everywhere">HTTPS Everywhere</a> and making sure every site you visit uses HTTPS is far more helpful than using a VPN.</p>
<h4>Should I use encrypted DNS with a VPN?</h4>
<p>The answer to this question is also not very helpful: <strong>it depends</strong>. Your VPN provider may have their own DNS servers, but if they don't, the traffic between your VPN provider and the DNS server isn't encrypted. You need to trust the <a href="/providers/dns/#icanndns">encrypted DNS provider</a> in addition to the VPN provider and unless your client and target server support <a href="https://www.eff.org/deeplinks/2018/09/esni-privacy-protecting-upgrade-https">encrypted SNI</a>, the VPN provider can still see which domains you are visiting.</p>
<p>However <strong>you shouldn't use encrypted DNS with Tor</strong>. This would direct all of your DNS requests through a single circuit, and would allow the encrypted DNS provider to deanonymize you.</p>
<p>Unless your VPN provider hosts the encrypted DNS servers, <strong>no</strong>. Using DOH/DOT (or any other form of encrypted DNS) with third party servers will simply add more entities to trust, and does <strong>absolutely nothing</strong> to improve your privacy/security. Your VPN provider can still see which websites you visit based on the IP addresses and other methods. Instead of just trusting your VPN provider, you are now trusting both the VPN provider and the DNS provider.</p>
<p>A common reason to recommend encrypted DNS is that it helps against DNS spoofing. However, your browser should already be checking for TLS certificates with <strong>HTTPS</strong> and warn you about it. If you are not using <strong>HTTPS</strong>, then an adversary can still just modify anything other than your DNS queries and the end result will be little different.</p>
<p>Needless to say, <strong>you shouldn't use encrypted DNS with Tor</strong>. This would direct all of your DNS requests through a single circuit, and would allow the encrypted DNS provider to deanonymize you.</p>
<h3>What if I need anonymity?</h3>
<p>VPNs cannot provide strong anonymity. Your VPN provider will still see your real IP address, and often has a money trail that can be linked directly back to you. You cannot rely on "no logging" policies to protect your data.</p>
