Whonix is a free, open-source desktop operating system built for anonymity, based on Debian and the hardened Kicksecure project. It ships as two virtual machines, a Gateway and a Workstation, that run inside VirtualBox or KVM on Windows, macOS, and Linux.

Our take
Whonix forces every connection through Tor by splitting your system into a gateway and a workstation, so an app that gets compromised still cannot leak your real IP. That design is its strength and its cost: you run it inside a VM, everything is Tor-slow, and it is overkill for ordinary browsing. Reach for it when isolation from IP leaks genuinely matters; for a portable anonymous session on a borrowed machine, Tails fits the job better.

secureblue secureblue is a security-hardened immutable Linux OS built on Fedora Atomic Desktops. It ships as OCI bootable container images and applies kernel hardening, a hardened memory allocator from GrapheneOS, and a hardened Chromium browser called Trivalent.
Kicksecure Kicksecure is a security-hardened Debian-based Linux distribution that applies a broad set of kernel and userspace hardening settings out of the box, reducing the attack surface without requiring manual configuration. It also serves as the foundation for the Whonix anonymity OS.
Fedora Atomic Desktops Fedora Atomic Desktops (Silverblue, Kinoite, and others) are immutable Fedora variants where the base OS is read-only and updated atomically via rpm-ostree. Applications run as Flatpaks, and rollback to a prior OS image is built in.
