What to check before hiring a CMMC assessor
Cyber AB authorization
Level 2 certification assessments require an authorized C3PAO. Check the Cyber AB Marketplace for current status.
Level 1 vs. Level 2 scope
Level 1 is an annual self-assessment; Level 2 usually requires a triennial C3PAO assessment. Make sure the firm matches your contract requirements.
NIST 800-171 depth
CMMC Level 2 is built on NIST SP 800-171. Ask how the firm handles POA&Ms, enclave scoping, and SSP review.
Defense supply-chain experience
Assessors who know DFARS 252.204-7012 and CUI flow-downs will scope your environment far more efficiently.
Frequently asked questions
Who can perform a CMMC Level 2 assessment?
Only a C3PAO (CMMC Third-Party Assessment Organization) authorized by the Cyber AB can perform Level 2 certification assessments. Level 1 and some Level 2 contracts allow self-assessment.
Is CMMC the same as NIST 800-171?
CMMC Level 2 is the DoD's certification mechanism for NIST SP 800-171 compliance. The controls are the same; CMMC adds the formal assessment and certification layer.
How were these CMMC firms ranked?
Disclosed featured entries appear first. Other firms are ordered by verification status, profile completeness, and verified client reviews. Confirm current C3PAO authorization on the Cyber AB Marketplace.
