Frequently Asked Questions

What is CMMC?
The Cybersecurity Maturity Model Certification (CMMC) is a framework developed by the Department of Defense (DoD) to ensure that defense contractors adequately protect Federal Contract Information (FCI) and Controlled Unclassified Information (CUI). It establishes three progressive levels of cybersecurity maturity that contractors must achieve to be eligible for DoD contracts.
What is the difference between a C3PAO and an RPO?
A C3PAO (CMMC Third-Party Assessment Organization) is authorized to conduct official CMMC certification assessments. An RPO (Registered Provider Organization) provides consulting and preparation services to help organizations get ready for their CMMC assessment. Some organizations hold both designations (Dual Authorized).
How are providers in this directory verified?
Every provider listed in this directory has been verified against the official Cyber AB Marketplace, which is the authoritative catalog maintained by The Cyber AB (the CMMC accreditation body). We confirm organization-level C3PAO and RPO authorizations directly from this source.
Is this directory affiliated with the DoD or Cyber AB?
No. This is an independent directory designed to help defense contractors find verified CMMC compliance providers. We are not affiliated with, endorsed by, or sponsored by the U.S. Department of Defense or The Cyber AB. Always verify provider credentials independently.
