Tails or The Amnesic Incognito Live System is a security-focused Debian-based Linux distribution aimed at preserving privacy and anonymity. All its outgoing connections are forced to go through Tor, and non-anonymous connections are blocked. The system is designed to be booted as a live DVD or live USB, and will leave no digital footprint on the machine unless explicitly told to do so. The Tor Project has provided financial support for its development.
Tails was first released on 23 June 2009. It is the next iteration of development on Incognito, a Gentoo-based Linux distribution. The Tor Project has provided financial support for its development. Tails has also received funding from the Debian Project, Mozilla, and the Freedom of the Press Foundation.
Laura Poitras, Glenn Greenwald, and Barton Gellman have each said that Tails was an important tool they used in their work with National Security Agency whistleblower Edward Snowden.
As of release 3.0, Tails requires a 64-bit processor to run.
One may choose among a large number of languages when the system is booted.
On 3 July 2014, German public television channel Das Erste reported that the NSA's XKeyscore surveillance system contains definitions that match persons who search for Tails using a search engine or visit the Tails website. A comment in XKeyscore's source code calls Tails "a comsec mechanism advocated by extremists on extremist forums".
