Qubes OS is a free and open-source, security-oriented operating system for single-user desktop computing. Qubes OS leverages Xen-based virtualization to allow for the creation and management of isolated compartments called qubes.

Strong isolation
Isolate different pieces of software as if they were installed on separate physical machines using advanced virtualization techniques.

Template system
Use app qubes to share a root file system without sacrificing security using the innovative Template system.

Multiple operating systems
Use multiple operating systems at the same time, including Fedora, Debian, and Windows.

Disposables
Create disposables on the fly that self-destruct when shut down.

Whonix integration
Run Tor securely system-wide using Whonix with Qubes.

Device isolation
Secure device handling through isolation of network cards and USB controllers.
