       <p><strong>In most cases, VPNs do little to protect your privacy or enhance your security</strong>, unless paired with other changes.</p>
       <p>VPNs cannot encrypt data outside of the connection between your device and the VPN server. VPN providers can see and modify your traffic the same way your ISP could. And there is no way to verify a VPN provider's "no logging" policies in any way.</p>
       <h3>What if I need encryption?</h3>
-      <p>In most cases, your traffic is already encrypted! Over 98% of the top 3000 websites offer <strong>HTTPS</strong>, meaning your 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>

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 the 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>
       <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>
