About Tails

The Amnesic Incognito Live System (Tails) is a Debian-based live CD/USB with the goal of providing complete Internet anonymity for the user. The product ships with several Internet applications, including web browser, IRC client, mail client and instant messenger, all pre-configured with security in mind and with all traffic anonymised. To achieve this, Incognito uses the Tor network to make Internet traffic very hard to trace.
