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
- The Florence virtual keyboard can now be used with touchpads again.
- Tails Installer does not list devices that are too small to be supported.
- Security fixes
- Upgrade to Linux 3.16.7-ckt2-1.
- Upgrade to Tor Browser 4.0.3 (based on Firefox 31.4.0esr) (ticket #8700).
- Improve MAC spoofing fail-safe mechanisms, which includes preventing one more way the MAC address could be leaked. (ticket #8571).
