How we test and rate VPNsWe complete standardized hands-on tests for each VPN we review so we can put their claims to the test. This includes vigorous third-party testing by comparing our internet speed while connected to different servers, checking for DNS leaks, making sure the kill switch actually works, and more. We also make sure we can comfortably access popular streaming sites, like Netflix, and still do our day-to-day work without interruption.
