We've already mentioned that the latest AdGuard for Windows update features a bunch of new low-level settings. Or go to and check if it says SSL_ECH_STATUS: success.Go to and see if it says sni=encrypted.Enable the Use Encrypted ClientHello feature.But, we're currently working on solving this issue. As the Use Encrypted ClientHello feature is experimental, it may also lower your browsing speed a bit. But thanks to AdGuard, ECH support will automatically work in all apps and browsers on your device. Chrome and Firefox, for example, are in the process of adding it. Today, ECH support is implemented in a limited number of apps. Note that Encrypted ClientHello technology can only work when supported on both client and server sides. However, if you update the app with the DNS module already enabled and configured, no changes will occur. The same will happen if you update the app with the DNS module disabled. Upon running AdGuard for Windows after a clean installation, DNS protection will be turned on with the system DNS server and AdGuard DNS filter enabled. The thing is that ECH relies on data obtained through DNS, so in order for AdGuard to receive this data and enable ECH globally for users, DNS filtering is necessary. And this is the main reason why we've enabled DNS Protection by default for all users, new and old ones. AdGuard's Encrypted ClientHello support implementationįor the Use Encrypted ClientHello feature to work, Block ECH must be disabled and DNS Protection - enabled. Encrypted ClientHello (ECH) is a new technology that should solve this problem and encrypt the very last unencrypted bit of information. This packet remains unencrypted, allowing the ISP to track which website you are accessing.

Enabling this experimental feature will make your connection even more secure.ĬlientHello is the very first packet of an encrypted connection which contains the name of the server you are communicating with. Now, however, we will focus on only one of them: Use Encrypted ClientHello. With this release, AdGuard for Windows gained 17(!) new low-level settings. Experimental Encrypted ClientHello support It's finally time for a change, and for a good reason: we've released a new version, and it boasts significant improvements that are worth telling you about. It's been a long time since we've had a blog post about AdGuard for Windows.
