C3PAO Assessment Organizations

CMMC Third-Party Assessment Organizations authorized to conduct official CMMC certification assessments.

What is a C3PAO?

A C3PAO (CMMC Third-Party Assessment Organization) is authorized by The Cyber AB to evaluate whether an organization meets the required CMMC maturity level and to recommend certification. C3PAOs perform the formal, independent assessments that lead to CMMC certification.

When do you need a C3PAO?

You need a C3PAO when you are ready for your official CMMC certification assessment. This is the final step, after you have prepared your organization, implemented all required controls, and are confident you meet the target CMMC level.
