TL;DR: CMMC 2.0 shifts U.S. defense contracting from periodic assessments to continuous compliance, with SecurityScorecard citing that 58% of breaches affecting the top 100 federal contractors involve third-party attack vectors, roughly twice the global average. Point-in-time controls now matter less than sustained evidence, subcontractor oversight, and audit-ready monitoring.
NHIMG editorial — based on content published by SecurityScorecard: CMMC 2.0 changes cybersecurity requirements for U.S. defense contractors and their supply chains
By the numbers:
- SecurityScorecard research shows that 58% of breaches affecting the top 100 U.S. federal contractors involve third-party attack vectors.
- 72% of organisations have experienced or suspect they have experienced a breach of non-human identities, 46% confirmed and 26% suspected.
Questions worth separating out
Q: What breaks when third-party risk is not built into CMMC readiness?
A: CMMC readiness breaks when supplier access is treated as outside the control boundary.
Q: Why does CMMC 2.0 make continuous monitoring more important than annual assessments?
A: Annual assessments only show a point in time, while CMMC 2.0 expects evidence that controls remain effective throughout the year.
Q: What do security teams get wrong about subcontractor compliance in the DIB?
A: Teams often assume contract language or self-attestation is enough.
Practitioner guidance
- Implement continuous compliance evidence collection Capture control telemetry, remediation history, and exception handling as part of normal operations so audit evidence is available on demand, not rebuilt under deadline.
- Extend third-party risk reviews into identity governance Assess subcontractor access, delegated accounts, and service identities alongside standard supplier questionnaires so third-party exposure is visible in access decisions.
- Map CMMC requirements to NIST control ownership Assign named owners for each relevant NIST 800-171 control and verify that evidence exists for operation, monitoring, and remediation across the reporting period.

Continuous assurance is now a compliance control, not a reporting preference. CMMC 2.0 effectively folds security monitoring into eligibility, which means contractors can no longer treat evidence as a year-end exercise. The governance shift is from proving that controls once existed to proving that they are still operating. For practitioners, that changes the design of audit-ready security programmes.
A question worth separating out:
Q: Who is accountable when a supplier causes a CMMC failure?
A: Accountability sits with the contractor that must prove compliance, even if the weakness originated with a subcontractor. The prime remains responsible for ensuring the supplier’s access, controls, and evidence can withstand audit scrutiny. That is why supply-chain governance, not just procurement oversight, belongs in the compliance programme.
