TL;DR: Zero Networks says CMMC is moving from policy to contract enforcement as Level 1, 2 and 3 requirements map to FAR 52.204-21, NIST SP 800-171 Rev. 2 and NIST SP 800-172 through 2028. Identity control quality, not documentation volume, is now the practical test of whether contractor environments can protect FCI and CUI.
Editorial analysis by NHI Mgmt Group, based on content published by Zero Networks: “CMMC Compliance: How to Meet New Cybersecurity Requirements”.
By the numbers:
- The average cost of a data breach in the United States hit $10.22 million in 2025, a 9% year-over-year increase.
- CMMC Level 2 maps to 110 requirements across 14 categories, including Access Control, Audit & Accountability, Identification & Authentication and System & Communications Protection.
- Phase 4 begins after November 10, 2028, when CMMC requirements are fully integrated across the DoD acquisition process.
Key questions
Q: What breaks in CMMC 2.0 when identity controls are only documented, not enforced?
A: The control set becomes hard to verify.
Q: Why do segmented networks matter so much for CMMC compliance?
A: Because authentication alone does not stop lateral movement.
Q: What do teams get wrong about CMMC evidence collection?
A: They treat evidence as a pre-audit deliverable instead of an operating process.
Practitioner guidance
- Map CMMC controls to identity-owned evidence Assign clear owners for access control, authentication, logging and boundary protection evidence so assessment readiness does not depend on ad hoc document collection.
- Extend governance to non-human access paths Inventory service accounts, integrations and automated workflows that can reach FCI or CUI, then document their authentication, privilege scope and offboarding process.
- Build segmentation evidence into compliance testing Demonstrate that contractor systems handling sensitive information are isolated into enforceable zones, with access paths tested against lateral movement scenarios.
Bottom line: CMMC is turning identity and access control into a contractual obligation for defence suppliers, subcontractors and related service providers.

CMMC is forcing identity governance to become evidentiary, not aspirational. The framework’s value is not in the labels attached to its levels but in the requirement to prove access control, authentication, logging and segmentation across real contractor environments. That shifts IAM from policy ownership to control verification, which is exactly where many programmes are weakest. Practitioners should treat every CMMC requirement as an evidence-producing control, not a statement of intent.
A few things that frame the scale:
- 92% of organisations expose NHIs to third parties, raising concerns about supply chain security, according to the Ultimate Guide to NHIs.
- The global average cost of a data breach reached $4.99 million in 2026, up 12% on the previous year, according to IBM's 2026 Cost of a Data Breach Report.
A question worth separating out:
Q: How should contractors prepare for CMMC without overfocusing on paperwork?
A: Start with the controls most likely to fail under real operational pressure: access restriction, authentication, audit trails, external connection control and segmentation. Then tie those controls to named owners, evidence sources and review cadence. That approach turns CMMC into a programme of measurable control performance rather than a document repository.
