On September 10, the Department of Defense published the Cybersecurity Maturity Model Certification (CMMC) final rule in the Federal Register. This milestone sets the stage for Phase 1 to officially begin on November 10, 2025.
For defense contractors, the implications are immediate and profound. The rule is no longer a draft, and certification is no longer optional. CMMC has moved from theory into enforceable regulation.
The release of the final rule creates a definitive pivot point:
The gap between today’s publication and November’s enforcement date is short. Contractors handling controlled unclassified information (CUI) who have not already scheduled assessments are facing a compressed timeline. The defense industrial base is vast, but the number of accredited C3PAOs remains limited. Demand will rise sharply, and organizations that delay may find themselves competing for scarce assessment capacity.
CMMC is not just about regulatory compliance. It is about trust and competitiveness within the defense supply chain. Contractors who achieve certification early will not only meet requirements but also signal reliability and resilience to their government customers. Those who wait risk being sidelined from future opportunities.
Since the inception of CMMC, we have been on the front lines supporting contractors through evolving drafts, provisional assessments, and now into the enforceable era. Our mock assessments are designed to provide clarity and confidence while our official assessments ensure impartiality and continuity so contractors can move forward without disruption.
The transition from planning to enforcement is here. The question is no longer if CMMC will impact your contracts, but when. For many, the answer is starting November 10.
CMMC certification is a milestone, but it does not have to be a struggle. Our team has been part of this journey since day one, giving contractors the insight and confidence they need to succeed. Connect with us today to take the next step with certainty.
