Security-focused operating system

This is a list of operating systems specifically focused on security. Similar concepts include security-evaluated operating systems that have achieved certification from an auditing organization, and trusted operating systems that provide sufficient support for multilevel security and evidence of correctness to meet a particular set of requirements.

Linux

Android-based

DivestOS is a fork of LineageOS that aims to increase privacy and security.
GrapheneOS is a privacy and security-focused mobile operating system for selected Google Pixel smartphones and tablets.

Debian-based

Tails is aimed at preserving privacy and anonymity.^[1]
Whonix consists of two virtual machines. All communications are forced through Tor.^[2]^[3]^[4]

Other Linux distributions

Alpine Linux is designed to be small, simple, and secure.^[5] It uses musl, BusyBox, and OpenRC instead of the more commonly used glibc, GNU Core Utilities, and systemd.^[6]
Owl - Openwall GNU/Linux, a security-enhanced Linux distribution for servers.

BSD

OpenBSD is a Unix-like operating system that emphasizes portability, standardization, correctness, proactive security, and integrated cryptography.^[7]

Xen

Qubes OS aims to provide security through isolation.^[8] Isolation is provided through the use of virtualization technology. This allows the segmentation of applications into secure virtual machines.
