Tails

Tails, short for The Amnesic Incognito Live System, is a free and open-source Linux operating system designed to protect privacy, anonymity and digital freedom. Unlike a conventional distribution installed on an internal drive, it is primarily used from a USB drive. It temporarily starts a computer in a separate environment without relying on the operating system already installed.

Its defining feature is its amnesic operation. By default, session data is not retained after shutdown. Files, history, settings and activity from the session disappear unless the user deliberately enables encrypted Persistent Storage on the USB drive.

Tails routes internet connections through Tor to reduce exposure to surveillance, tracking and online censorship. Its intended audiences include journalists, whistleblowers, activists, researchers, human-rights defenders, people affected by censorship and users seeking stronger digital privacy.

Tails began in the late 2000s as a live system intended to protect anonymity. It followed earlier work involving Tor and privacy-focused live distributions. Its name highlights two ideas: amnesia, or not retaining session traces by default, and incognito operation, aimed at protecting the user’s identity.

Over time, Tails became well known in digital privacy. Journalists, NGOs, activists and people needing a safer computing environment have used it. Its reputation rests on Tor integration, live operation, documentation and efforts to reduce configuration mistakes.

Tails developed for many years as an independent project closely connected to the Tor ecosystem. The official website now identifies Tails as a Tor Project product, bringing the operating system, Tor Browser and privacy tools under a shared organisation.

The original profile described Tails 7.8, released on 21 May 2026. That release updated Tor Browser to 15.0.14, removed Thunderbird from the default installation and fixed security vulnerabilities in the Linux kernel and haveged. These are historical release details, not a claim that 7.8 remains the latest version.

Tails can run live from a USB drive without installing onto the internal disk. This provides an environment separate from the installed system and reduces the likelihood of leaving local session data behind.

Tor is integrated by default. Network connections are designed to pass through Tor, helping conceal the user’s original IP address and bypass some forms of censorship. The integrated setup reduces the configuration work involved in assembling separate privacy tools on a conventional system.

The amnesic design means session data is not normally retained between boots. This can be useful on shared or borrowed computers, allowing a fresh session after restarting. It does not remove the need to consider whether the hardware itself is trustworthy.

Encrypted Persistent Storage allows users to keep selected files, settings, keys, bookmarks and additional software on the USB drive. Users can choose a temporary session or a portable environment with deliberately retained encrypted data.

Tails includes privacy tools such as Tor Browser, encryption utilities, password management and security-oriented settings. Regular updates address vulnerabilities and follow Tor Browser development.

Tails is not designed as a conventional permanently installed distribution for every daily task. It is principally a temporary live system. Ubuntu, Debian, Fedora, Linux Mint or Zorin OS may be more convenient for ordinary office work, a family computer or a main workstation.

It can be slower than a system installed on a drive, particularly when using a slow USB device. Startup, application launches and other operations depend partly on the USB drive’s quality. A reliable, reasonably fast drive is therefore useful.

Tor also generally provides lower network performance than a direct connection. Pages may load slowly, some services block Tor connections and others require extra verification. These constraints are part of the trade-off involved in using the anonymity network.

Tails does not protect against every threat or make a user invisible or invulnerable. Mistakes, unsuitable document handling, personal accounts, identifying behaviour and targeted attacks can still compromise anonymity. Its protections require an understanding of their limits.

Tails does not run on smartphones or tablets. The official documentation explains that these devices differ too much from supported computers for Tails to run on them as it does on a conventional PC.

Tails does not have a range of desktop editions like Ubuntu, Fedora or Manjaro. It mainly provides one official system, distributed as a USB image or an ISO for DVDs and virtual machines. Installation on a USB drive is the recommended approach.

Tails 7.8, released on 21 May 2026 and discussed in the original profile, updated Tor Browser to 15.0.14 and removed Thunderbird from the default installation. Thunderbird could still be installed as additional software when needed. Consult the official download page for the current release.

Tails 7.8 also fixed security vulnerabilities in the Linux kernel and haveged. Such fixes matter because a local vulnerability may allow a compromised application to obtain greater privileges and threaten anonymity.

Tails supports automatic upgrades from some earlier releases. The 7.8 release notes documented automatic upgrades from Tails 7.0 or later to 7.8, with a manual upgrade available if that failed. For a current installation, follow the instructions for the actual versions involved.

Since Tails 7.7, the system has also been able to detect outdated Secure Boot certificates on some computers and warn when an update is required. This addresses the gradual expiry of some older Secure Boot certificates beginning in June 2026.

Tails is a specialised live Linux system designed to protect privacy, reduce local traces and integrate Tor. It does not replace a conventional distribution for every use, but addresses the specific need for a temporary, portable, amnesic computing environment.

For journalists, activists, researchers, whistleblowers and people facing surveillance or censorship, it can be a useful tool. Users must understand its limitations and follow official recommendations. For sensitive work, obtaining the latest official release and keeping Tails updated is essential.
