- CMMC Third-Party Assessment Organization
A CMMC Third-Party Assessment Organization (C3PAO) is an entity accredited by the Cyber AB to perform CMMC Level 2 assessments on behalf of DoD contractors. C3PAOs are not used at Level 1, Level 1 is exclusively self-assessed, and they are not used at Level 3, which is assessed by DIBCAC. The DoD suspension of CMMC Phase 2 on July 13, 2026 paused the rollout that would have required C3PAO assessments on covered contracts beginning November 10, 2026, and the memo cites severe shortages in third-party assessment capacity as one reason for the review.
- Certified CMMC Assessor
A Certified CMMC Assessor (CCA) is an individual credentialed by the Cyber AB to lead CMMC Level 2 assessments under a C3PAO. CCAs are not required for Level 1, and the credential itself does not authorize anyone to issue a Level 1 certification.
- Certified CMMC Professional
A Certified CMMC Professional (CCP) is the baseline credential issued by the Cyber AB for individuals participating in the CMMC ecosystem. CCPs may serve as assessment team members under a CCA, but the credential alone does not authorize them to lead assessments or issue certifications.
