Tails helps you to:

  • use the Internet anonymously and circumvent censorship
  • all connections to the Internet are forced to go through the Tor network
  • leave no trace on the computer you are using unless you ask it explicitly
  • use state-of-the-art cryptographic tools to encrypt your files, emails and instant messaging

Tails is a live system that aims to preserve your privacy and anonymity. It helps you to use the Internet anonymously and circumvent censorship almost anywhere you go and on any computer but leaving no trace unless you ask it to explicitly.

It is a complete operating system designed to be used from a DVD, USB stick, or SD card independently of the computer's original operating system.

Tails comes with several built-in applications pre-configured with security in mind: web browser, instant messaging client, email client, office suite, image and sound editor, etc.

If you are interested in giving Tails a try on your current computer without running any risk, please check out our Guide: Running Linux From a USB Drive As a Virtual Machine or Bootable Disk.

Online anonymity and censorship circumvention with Tor

Tails relies on the Tor anonymity network to protect your privacy online:

  • all software is configured to connect to the Internet through Tor
  • if an application tries to connect to the Internet directly, the connection is automatically blocked for security.

Tor is free software and an open network that helps you defend against a form of network surveillance that threatens personal freedom and privacy, confidential business activities and relationships, and state security known as traffic analysis.

Tor protects you by bouncing your communications around a distributed network of relays run by volunteers all around the world: it prevents somebody watching your Internet connection from learning what sites you visit, and it prevents the sites you visit from learning your physical location.

Using Tor you can:

  • be anonymous online by hiding your location
  • connect to services that would be censored otherwise
  • resist attacks that block the usage of Tor using circumvention tools such as bridges

What's New:

Beta 1.1

  • Based on Debian 7 Wheezy
  • Windows 8 camouflage

Tails, The Amnesic Incognito Live System, version 1.0, is out.

All users must upgrade as soon as possible: this release fixes numerous security issues.

Notable user-visible changes include:

  • Security fixes
    • Upgrade the web browser to 24.5.0esr-0+tails1~bpo60+1 (Firefox 24.5.0esr + Iceweasel patches + Torbrowser patches).
    • Upgrade Tor to 0.2.4.21-1+tails1~d60.squeeze+1:
      • Based on 0.2.4.21-1~d60.squeeze+1.
      • Backport the fix for bug #11464 on Tor Project's Trac. It adds client-side blacklists for all Tor directory authority keys that was vulnerable to Heartbleed. This protects clients in case attackers were able to compromise a majority of the authority signing and identity keys.
  • Bugfixes
    • Disable inbound I2P connections. Tails already restricts incoming connections, but this change tells I2P about it.
    • Fix link to the system requirements documentation page in the Tails Upgrader error shown when too little RAM is available.
  • Minor improvements
    • Upgrade I2P to 0.9.12-2~deb6u+1.
    • Import TorBrowser profile. This was forgotten in Tails 0.23 and even though we didn't explicitly set those preferences in that release they defaulted to the same values. This future-proofs us in case the defaults would ever change.
    • Import new custom version of Tor Launcher:
      • Based on upstream Tor Launcher 0.2.5.3.
      • Improve how Tor Launcher handles incomplete translation. (bug #11483 on Tor Project's Trac; more future-proof fix for ticket #6885)
      • Remove the bridge settings prompt. (bug #11482 on Tor Project's Trac; closes ticket #6934)
      • Always show bridge help button. (bug #11484 on Tor Project's Trac)
    • Integrate the new Tails logo into various places:
      • The website
      • The boot splash
      • The "About Tails" dialog
