# RLC Pro Hardened Discussions

Government, defense, and financial services teams that carry hardening and remediation as a permanent manual project can start from an operating system that ships the hardening. RLC Pro Hardened is the hardened tier of the RLC family from CIQ and builds on Rocky Linux from CIQ Pro (RLC Pro). It ships STIG, CIS, and CUI (NIST 800-171) security profiles, maintained and supported so they do not drift between audits. The profile is chosen at install, one per build, and the remaining controls are site-specific. FIPS 140-3 validation comes with LTS releases, per minor version and architecture. RLC Pro Hardened ships Linux Kernel Runtime Guard (LKRG), which detects kernel tampering, privilege escalation, and rootkit behavior on a running system and can feed a SIEM as a sensor. LKRG detects exploitation attempts. It does not prevent them, and it does not replace patching.
