CMMC 2.0 Level 2: What Defense Contractors Need to Know

CMMC Level 2 aligns to the 110 controls of NIST SP 800-171 and now requires a C3PAO assessment for many contracts. Here is how to prepare.

The Cybersecurity Maturity Model Certification (CMMC 2.0) is now a contract-keeping requirement for defense contractors handling Federal Contract Information (FCI) or Controlled Unclassified Information (CUI). Understanding where you fall — and how to prepare — is the difference between keeping and losing a DoD contract.

Level 1 vs. Level 2

CMMC Level 1 protects Federal Contract Information (FCI) and aligns to 17 basic safeguards. It is self-assessed.

CMMC Level 2 protects Controlled Unclassified Information (CUI) and aligns to the 110 controls of NIST SP 800-171. Higher-value Level 2 contracts require a C3PAO assessment — a third-party assessment by a Certified Third-Party Assessment Organization.

What the assessment actually measures

A CMMC assessment verifies that your 110 controls are not only documented but implemented and operating. Assessors review your System Security Plan (SSP), your Plan of Action and Milestones (POA&M), your CUI boundary, and the evidence supporting each control.

How to prepare

  1. Run a gap assessment against the 110 NIST SP 800-171 controls.
  2. Rewrite your SSP and POA&M so they accurately reflect your environment.
  3. Implement the remaining technical controls and stand up a CUI enclave.
  4. Run a mock assessment before your C3PAO visit.
