CMMC crypto controls: inventory evidence auditors want

Defense contractors face CMMC Level 2 enforcement between 2026 and 2030. Primes and assessors increasingly ask for cryptographic inventory evidence — not verbal assurance.

CMMC Level 2 cryptographic inventory evidence checklist.

What CMMC expects

CMMC 2.0 Level 2 aligns with NIST SP 800-171 controls around cryptographic module validation, key management, and protection of CUI. Assessors want evidence that you:

  • Know which algorithms protect CUI in transit and at rest
  • Have a migration plan for quantum-vulnerable cryptography
  • Can demonstrate progress between assessment cycles

Evidence that works

ArtifactPurpose
Live TLS inventoryExternal attack surface with algorithm tags
CycloneDX CBOMMachine-readable asset list for GRC
Signed scan report + /verifyIndependent signature check
Drift diff between scansProves monitoring, not one-time panic

What does not work

  • Annual spreadsheet exercises that go stale within weeks
  • Vendor attestation letters without algorithm-level detail
  • Claiming "we use TLS 1.3" without inventory of certificate algorithms

Qtangl for DIB contractors

Qtangl maps findings to CMMC-relevant controls, exports signed compliance packs, and Monitor tier tracks drift between cycles. This is an inventory aid — not a formal CMMC attestation.
