Security-focused operating system

Short description: Operating systems focused on security

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

Main article: Software:Linux

### Android-based

Main article: Software: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: Software:Arch Linux

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

### Debian-based

Main article: Software: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: Software: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: Software:Berkeley Software Distribution

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

## Xen

Main article: Software: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.
