TL;DR: The DoD’s final CMMC rule takes effect on November 10, 2025, making certification and continuous compliance a condition for many contracts handling FCI or CUI, with phased self-assessments, third-party audits for higher-risk work, and potential ineligibility for awards if requirements are not maintained, according to Proofpoint. Continuous control evidence, not point-in-time paperwork, now becomes the practical test of supply-chain readiness.

Questions worth separating out
Q: What breaks when CMMC compliance is treated as a one-time audit exercise?
A: A one-time audit approach breaks down because CMMC ties contract eligibility to sustained control effectiveness, not a temporary snapshot.
Q: Why do access controls matter so much under CMMC Phase 2?
A: Access controls matter because Phase 2 moves CMMC from paper compliance to third-party validation of operational enforcement.
Q: How can organisations know whether CMMC control evidence is actually reliable?
A: Control evidence is reliable when it is generated from live systems, updated regularly, and tied to remediated findings rather than static spreadsheets.
Practitioner guidance
- Map CMMC controls to identity evidence Create an evidence matrix that ties MFA enforcement, access review cadence, and privileged account ownership to the specific CMMC controls your contracts depend on.
- Inventory CUI repositories continuously Use data discovery and classification to maintain a live inventory of systems storing Federal Contract Information and Controlled Unclassified Information.
- Track identity misconfigurations as audit blockers Build remediation queues for inactive accounts, excessive permissions, and missing MFA.

CMMC 2.0 turns identity governance into procurement infrastructure: once compliance status determines contract eligibility, access review, authentication, and logging are no longer back-office hygiene. They become evidence-bearing controls that affect whether a contractor can win and retain work. That shift favours programmes that can prove entitlement accuracy, control continuity, and exception handling at scale. Practitioners should treat identity governance as part of bid readiness, not just audit support.
A question worth separating out:
Q: Who is accountable when CMMC scope decisions are wrong?
A: Accountability sits with the organisation’s compliance leadership and the Affirming Official who signs the determination, especially when the decision affects assessment scope or contract eligibility. That is why scope changes need documented review, change control, and evidence that the final decision was made against current system reality.
