Whonix is an operating system focused on anonymity, privacy and security. It is based on the Tor anonymity network, Debian GNU/Linux and security by isolation. Whonix consists of two parts: One solely runs Tor and acts as a gateway, which is called Whonix-Gateway. The other, which is called Whonix-Workstation, is on a completely isolated network. Only connections through Tor are possible. With Whonix, you can use applications and run servers anonymously over the Internet. DNS leaks are impossible, and even malware with root privileges cannot find out the user's real IP.
