1. Overview of CMMC Compliance
The Cybersecurity Maturity Model Certification (CMMC) is a mandatory security framework established by the U.S. Department of Defense (DoD) to ensure that contractors and suppliers protect sensitive government information. If your business handles Controlled Unclassified Information (CUI) or Federal Contract Information (FCI), compliance with CMMC is required to win and maintain DoD contracts.
With the introduction of CMMC 2.0, organizations must meet one of three security maturity levels, aligned with NIST 800-171 standards:
CMMC 2.0 Maturity Levels
Level 1 – Foundational
- Applies to organizations handling Federal Contract Information (FCI)
- Requires annual self-assessments
- Focuses on basic cybersecurity hygiene, such as access control and user authentication
Level 2 – Advanced
- Applies to organizations handling Controlled Unclassified Information (CUI)
- Requires third-party assessments for critical contractors
- Aligns with NIST 800-171 and includes 110 security controls
Level 3 – Expert
- Applies to organizations handling highly sensitive DoD information
- Requires triennial government-led audits
- Based on NIST 800-172 with advanced threat detection and zero-trust security
Compliance is essential for:
- Prime contractors and subcontractors in the defense supply chain
- Manufacturers, IT providers, and other service contractors
