CMMC 2.0 is here, and it’s changing the game for defense contractors. If you’re in the Defense Industrial Base (DIB), understanding CMMC is critical to keeping your DoD contracts.
What Changed with CMMC 2.0
CMMC 2.0 streamlined the original 5-level model into 3 levels, aligned more closely with existing NIST standards, and introduced self-assessment options for Level 1. But Level 2 and Level 3 still require third-party and government assessments respectively.
The Three Levels
Level 1 (Foundational): 17 practices based on FAR 52.204-21. Self-assessment allowed.
Level 2 (Advanced): 110 practices aligned with NIST SP 800-171. Third-party assessment required for critical national security information.
Level 3 (Expert): 110+ practices based on NIST SP 800-172. Government-led assessment required.
Timeline and Enforcement
CMMC requirements are being phased into DoD contracts starting 2025. By 2026, most new contracts will require demonstrated CMMC compliance at the appropriate level.
