The Cybersecurity Maturity Model Certification (CMMC) program, managed by The Cyber AB (formerly known as the CMMC Accreditation Body or the CMMC-AB), is designed to validate defense contractors' compliance with the cybersecurity practices required by their contracts. Once rulemaking has concluded and CMMC 2.0 has been fully implemented, all organizations providing products or services to the United States Department of Defense (DoD) must achieve the CMMC level required in the desired contract.
