CMMC Compliance Audit: What Defense Contractors Must Know
Learn what a CMMC compliance audit involves and how defense contractors can prepare for assessment.
If your company handles Controlled Unclassified Information for the Department of Defense, a CMMC compliance audit is no longer a hypothetical. With CMMC 2.0 enforcement now active, defense contractors at every tier must demonstrate compliance through formal assessment. The question is not whether you will face a CMMC compliance audit, but how prepared you will be when it arrives.
CMMC Compliance Audit Overview
A CMMC compliance audit is a structured evaluation of your organizations cybersecurity practices against the Cybersecurity Maturity Model Certification framework. For most defense contractors handling CUI, this means meeting the 110 security requirements outlined in NIST SP 800-171, mapped to CMMC Level 2.
The audit examines three dimensions: your documented policies and procedures, your technical implementation of security controls, and evidence that those controls operate effectively over time. Auditors will review your System Security Plan, examine your Plan of Action and Milestones, and test controls through interviews, observations, and technical verification.
Self-Assessment vs Third-Party Audit
CMMC 2.0 offers two assessment paths depending on your required level. Level 1 and some Level 2 contracts allow self-assessment, where your organization evaluates its own compliance and affirms the results. Level 2 contracts involving prioritized acquisitions and all Level 3 contracts require assessment by a Certified Third-Party Assessment Organization (C3PAO).
