The 110 Controls That Decide Your Future: How NIST 800-171 Maps to CMMC Level 2

The 110 Controls That Decide Your Future: How NIST 800-171 Maps to CMMC Level 2

CMMC Level 2 equals full NIST 800-171 implementation. Learn the 110 controls that define readiness, the top evidence failures, and how Deep Fathom automates proof to keep compliance continuous.

Deep Fathom

The Economic Divider

CMMC 2.0 Level 2 isn’t an upgrade. It’s the threshold for staying in most Department of Defense contracts that handle Controlled Unclassified Information.

At CS5 East, Deep Fathom showed what readiness looks like in motion: automation carrying the load while people stay in command.

The Framework in Plain English

NIST SP 800-171 defines 110 requirements across 14 control families: AC, AT, AU, CM, IA, IR, MA, MP, PS, PE, RA, CA, SC, SI.

Each control ties to assessment objectives in 171A, the reference used by DIBCAC and C3PAOs to verify evidence.

CMMC 2.0 Level 2 equals full NIST 800-171 plus third-party verification.

If your evidence aligns with 171A, you’re ready. If not, each unverified control is a risk on your balance sheet.

The Ten Most Frequent Failures

Public DIBCAC data highlights repeat weak points.

Control - Common Failure

3.1.1 - Access control unenforced
3.3.1 - Audit logging disabled
3.5.1 - MFA not applied to all users
3.7.2 - Patch records incomplete
3.9.2 - Termination process undocumented
3.10.1 - Physical access inconsistent
3.11.2 - Risk assessment outdated
3.12.1 - Annual self-assessment skipped
3.13.11 - Outbound traffic unmonitored
3.14.5 - Vulnerability scanning absent

Every one is an evidence failure, not a technology gap.

Continuous Evidence vs. Annual Panic

Traditional compliance means one frantic push each year.

Deep Fathom’s Agentic AI turns that into a continuous verification loop:

  • Collects and timestamps artifacts automatically.
  • Validates integrity and freshness.
  • Maps proof directly to control objectives.
  • Flags stale evidence for remediation before audit season starts.

Assessors see proof, not promises.

Level 2 as the Market Gatekeeper

Level 1 lets you exist in the Defense Industrial Base.

Level 2 lets you compete.

Without it, CUI-related opportunities close fast.

Primes now demand Level 2 alignment before subcontracting. Deep Fathom keeps readiness continuous across both primes and subs.

Better Together: Partner-Driven Readiness

RPOs, MSPs, and compliance consultants use Deep Fathom to unify client work under one live compliance layer.

The result is consistent readiness views, AI-verified evidence, and shared dashboards that replace fragmented reporting.

At CS5 East, partners called it “compliance with command.” They weren’t watching automation replace expertise—they were watching it scale it.

Conclusion

NIST 800-171 defines trust. CMMC 2.0 verifies it.

Deep Fathom operationalizes both through Agentic AI orchestration—evidence capture, validation, and audit-ready outputs that prove compliance continuously.

More Rigor. Radically Less Effort.

Deep Fathom isn't a checklist.

It's your compliance brain—structured, shared, and ready when it counts.
