secureblue is a security-focused desktop and server Linux operating system built as OCI bootable container images on top of Fedora Atomic Desktops using BlueBuild. It hardens the system with SELinux, hardened_malloc, kernel hardening, USBGuard, and attack-surface reductions while aiming to remain usable for everyday Linux users.
Use cases
- harden a desktop linux installation against exploits
- security-focused linux distro for daily use
- hardened server os built from coreos
- replace sudo and pkexec with run0 on linux
- lock down flatpak sandbox permissions
- immutable linux os with secure boot support
When to choose
- you already intend to use Linux and want the most secure practical option
- you want an immutable, image-based Fedora system with hardening preconfigured
- you need a hardened server or edge OS based on Fedora CoreOS
When to avoid
- security is your absolute first priority and you can use Qubes OS or similar
- you need broad compatibility with X11 apps, AppImages, or anti-cheat games without extra setup
- you want a traditional package-based distro with full customization of the base system
