secureblue brings a comprehensive, defense-in-depth approach to Linux. It hardens the system from top to bottom by integrating exploit mitigation tools (like hardened_malloc and hardened-chromium), removing unnecessary SUID-root binaries, disabling risky defaults (Xwayland, unprivileged user namespaces), and locking down system services. Through network time security (NTS) with chrony, opportunistic DNSSEC + DNS-over-TLS, plus robust container policies, secureblue reduces attack surface and blocks potential exploits early. It also streamlines security management with toggles for advanced features (e.g., LUKS TPM2 or FIDO2 drive unlocking) and ensures “secure by default” configuration, from firewall rules to blacklisted kernel modules. The result? 

A modern, hardened, and user-friendly Linux experience that emphasizes both proactive protections and ease-of-use.
