Tails is a privacy-focused Linux operating system that boots from a USB drive and leaves no trace on the host computer — all internet traffic is routed through Tor, and nothing is saved after shutdown unless explicitly specified. Unlike regular VPNs, Tails provides OS-level anonymity including protecting against local surveillance. Used by journalists at the Guardian, Reporters Without Borders, and whistleblowers (including Edward Snowden). Free and open-source, maintained by the Tails Project.

The verdict
Our take on Tails OS
