CMMC Level 3
Also known as: Level 3 · L3 · CMMC L3 · Expert
The Expert level of CMMC, applied to contractors supporting the most critical DoD programs. Assessed by DIBCAC, not C3PAOs.
CMMC Level 3 is the Expert tier of the CMMC 2.0 program. It is reserved for defense contractors supporting the highest-priority DoD programs where the consequences of compromise are most severe.
Level 3 builds on the 110 requirements of Level 2 and adds a subset of enhanced security requirements drawn from NIST SP 800-172. Unlike Levels 1 and 2, Level 3 assessments are conducted by the Defense Industrial Base Cybersecurity Assessment Center (DIBCAC) — a government team — rather than by commercial C3PAOs.
Level 3 is comparatively rare. Most contractors handling CUI need Level 2; Level 3 applies to a smaller population of programs the DoD has explicitly designated.
