TL;DR: CMMC now determines defense supply chain eligibility by tying compliance to contract-bound evidence, data sensitivity, and assessed control effectiveness rather than self-attestation, according to Cyberhaven. The shift makes visibility, documentation, and continuous enforcement core governance issues for IAM, access control, and audit readiness.

Questions worth separating out
Q: What breaks when CMMC is treated as a documentation exercise instead of an operating control model?
A: When CMMC is treated as paperwork, organisations usually discover that their controls are inconsistent, their evidence is stale, and their access governance cannot support what the assessment asks for.
Q: Why does CMMC place so much weight on data classification and access mapping?
A: Because the required level and assessment path depend on whether an organisation handles FCI or CUI, not on its size or industry.
Q: What do organisations get wrong about CMMC Level 2 readiness?
A: The most common mistake is treating readiness as a document review instead of an operating-state problem.
Practitioner guidance
- Map FCI and CUI to identity paths Identify where Federal Contract Information and Controlled Unclassified Information move, which accounts can reach them, and which systems store or process them.
- Convert access reviews into evidence workflows Turn periodic access reviews into recurring evidence-gathering processes that capture approvals, exceptions, revocations, and privileged access changes.
- Reduce standing privilege before assessment windows open Audit privileged accounts, service accounts, and subcontractor access for unnecessary persistence, then remove or constrain access that is not tied to a current contract need.

CMMC is increasingly an identity governance problem disguised as a compliance framework. The article treats certification as evidence of operational security, which is correct, but the control reality is that access paths, privileged accounts, and data scoping determine whether evidence can be trusted. For IAM and PAM teams, the issue is not only whether controls exist, but whether they are continuously provable under assessment conditions.
A question worth separating out:
Q: Who is accountable when a contractor cannot prove CMMC identity controls?
A: The contractor remains accountable, because CMMC shifts eligibility from self-reporting to third-party assessment. If identity controls are incomplete, poorly documented, or not aligned to the target maturity level, the organisation can lose the ability to bid at the contract level it is pursuing.
