In the same year, Der Spiegel published slides from an internal National Security Agency presentation dating to June 2012, in which the NSA deemed Tails on its own as a "major threat" to its mission and in conjunction with other privacy tools as "catastrophic".

A comment in XKeyscore's source code calls Tails "a comsec mechanism advocated by extremists on extremist forums". In 2014 Das Erste reported that the NSA's XKeyscore surveillance system sets threat definitions for people who search for Tails using a search engine or visit the Tails website. While shutting down, Tails overwrites most of the used RAM to avoid a cold boot attack. Though the Persistent Storage is encrypted by default, it is not hidden and detectable by forensic analysis. The user may choose to keep files, applications or some settings on their Tails drive in "Persistent Storage". It runs in the computer's Random Access Memory (RAM) and does not write to a hard drive or other storage medium. For networking, it features a modified version of Tor Browser with the inclusion of uBlock Origin, instant messaging, email, file transmission and monitoring local network connections for security. It tries to force all connections to use Tor and blocks connection attempts outside Tor. It is pre-configured to use Tor with multiple connection options.

Tails includes a unique variety of software that handles the encryption of files and internet transmissions, cryptographic signing and hashing, and other functions important to security.
Despite being open-source, Tails contains non-free firmware blobs. Other software from Debian can be installed at the user's behest. The system includes essential software for functions such as reading and editing documents, image editing, video watching and printing. Tails's pre-installed desktop environment is GNOME 3. įrom release 3.0, in 2017, Tails requires a 64-bit processor to run. Laura Poitras, Glenn Greenwald, Bruce Schneier and Barton Gellman have each said that Tails was an important tool they used in their work with National Security Agency whistleblower Edward Snowden. Tails also received funding from the Open Technology Fund, Mozilla, and the Freedom of the Press Foundation. The Tor Project provided financial support for its development in the beginnings of the project. The operational system was born when Amnesia was merged with Incognito. It is the next iteration of development on Incognito, a discontinued Gentoo-based Linux distribution.
Tails was first released on June 23, 2009. The Tor Project provided financial support for its development in the beginnings of the project, and continues to do so alongside numerous corporate and anonymous sponsors. It can also be run as a virtual machine, with some additional security risks. The system is designed to be booted as a live DVD or live USB and never writes to the hard drive or SSD, leaving no digital footprint on the machine unless explicitly told to do so.
It connects to the Internet exclusively through the anonymity network Tor. Tails, or " The Amnesic Incognito Live System," is a security-focused Debian-based Linux distribution aimed at preserving privacy and anonymity.
