Whonix is a privacy-focused operating system that routes all internet traffic through the Tor network. It is built on the hardened Linux distribution Kicksecure and runs as a set of virtual machines: a gateway that handles Tor connections and a separate workstation where applications run. Whonix can be used with VirtualBox, KVM or Qubes OS, and the website offers installation media for Windows, Linux and macOS hosts. Its focus is on anonymity and the isolation of activities.
The source code of Whonix is published under OSI-approved licences. The legal entity behind the project, Encrypted Support LLC, is described on the imprint as a series of OTOCO RMI LLC and is based in the Marshall Islands, outside the EU. Because Whonix runs on the user's own hardware or in local virtual machines, an organisation can install and inspect it independently. Dependence on a non-EU maintainer for releases and security fixes remains the main consideration.
