AdGuard DNS is a legitimate, well-established DNS service built by AdGuard, the same company behind its popular ad-blocking browser extensions and apps. It is generally considered safe and privacy-focused: AdGuard states it does not log personally identifiable browsing data, and its servers are used by millions of people worldwide. Unlike a browser extension, which only blocks ads and trackers inside that one browser, AdGuard DNS filters requests at the DNS level, before a connection is even made, so ads and trackers get blocked across every app and browser on your device rather than just one. As with any DNS provider, it's worth confirming resolution behaves as expected with our DNS lookup tool before switching your default DNS everywhere.
