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

Main article: Android (operating system)

CalyxOS is designed for privacy, security, and accessibility.^[1]
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.
Kali NetHunter is a mobile penetration testing platform based on Kali Linux.^[2]

Arch-based

Main article: Arch Linux

BlackArch is a penetration testing distribution that provides a large number of security tools.

Debian-based

Main article: Debian

Kali Linux is designed for digital forensics and penetration testing.^[3]
Parrot OS Security Edition is designed for penetration testing, vulnerability assessment and mitigation, computer forensics, and anonymous web browsing.^[4]
Tails is aimed at preserving privacy and anonymity.^[5]
Whonix consists of two virtual machines. All communications are forced through Tor.^[6]^[7]^[8]

Gentoo-based

Main article: Gentoo Linux

Pentoo is a Live CD and Live USB designed for penetration testing and security assessment.^[9]^[10]^[11]^[12]

Other Linux distributions

Alpine Linux is designed to be small, simple, and secure.^[13] It uses musl, BusyBox, and OpenRC instead of the more commonly used glibc, GNU Core Utilities, and systemd.^[14]
Fedora Silverblue is an immutable desktop operating system. Every Silverblue installation is identical to every other installation of the same version, and it never changes as it is used.^[15]

BSD

Main article: Berkeley Software Distribution

OpenBSD is a Unix-like operating system that emphasizes portability, standardization, correctness, proactive security, and integrated cryptography.^[16]

Xen

Main article: Xen

Qubes OS aims to provide security through isolation.^[17] Isolation is provided through the use of virtualization technology. This allows the segmentation of applications into secure virtual machines.
