Tails will never try to harm you or any of our users, as a core principle of our [[Social Contract|about/social_contract]]. As part of that commitment, we have written this page to help you make an informed decision about whether you can trust Tails.
Known issues in Tails are described publicly in our [[!tails_gitlab desc="GitLab issue tracker"]]. We might hide embargoed security vulnerabilities in Tails while we work on a solution, but only as a way of protecting our users.
[Debian](https://debian.org/) is one of the oldest Linux distributions and the one with the most derivatives, including Ubuntu. Debian and its derivatives are [the most popular Linux distributions on web servers](https://w3techs.com/technologies/details/os-linux) across the Internet. The Debian project is coordinated over the Internet by a team of volunteers whose work is entirely public. All this makes Debian one of the Free Software projects under the most scrutiny by security researchers.
