WARNING: EXPERIMENTAL / UNSTABLE RESEARCH PROJECT. NOT INTENDED FOR DAILY USE.

Hardened Slarpx is a Debian-based Linux distribution built with a strict security-first approach. It uses a multi-layered defense model with aggressive mitigations and extensive kernel-level hardening. Due to its highly restrictive firewall policy, anonymization tools and certain network protocols are intentionally unsupported. The distribution includes there custom runtime security modules: Poison , Xennytsu and Silencer. Beyond passive hardening, Slarpx focuses on active intervention, sabotage, and destruction of attack paths when necessary.

User Reviews

  • This distribution might be the most secure one I've seen since Qubes. The Poison module is very well thought out. This developer is an inventor.
