Cybersecurity Maturity Model Certification (CMMC)
Protecting Federal Contract and Controlled Unclassified Information across the Defense Industrial Base
What is CMMC?
The Cybersecurity Maturity Model Certification (CMMC) is a U.S. Department of Defense cybersecurity program designed to ensure that contractors and subcontractors meet required safeguards to protect sensitive government data.
CMMC focuses on protecting:
- Federal Contract Information (FCI): Non-public information related to government contracts.
- Controlled Unclassified Information (CUI): Sensitive information that requires safeguarding as defined by law, regulation, or government-wide policy.
Why CMMC Matters
- CMMC strengthens cybersecurity across the entire defense industrial base.
- Certification is becoming a requirement to win or maintain DoD contracts.
- Cybersecurity expectations are standardized across prime contractors and subcontractors.
- It reduces the risk of unauthorized access to sensitive national security information.
CMMC 2.0 — The Three Certification Levels
Level 1 – Basic Safeguarding (FCI)
- 15 basic cybersecurity practices.
- Protects Federal Contract Information.
- Annual self-assessment and annual affirmation required.
- No POA&Ms allowed at this level.
Level 2 – Advanced (CUI)
- 110 practices aligned with NIST SP 800-171.
- Protects Controlled Unclassified Information.
- Assessment may be self-assessment or performed by a certified third-party assessment organization (C3PAO) depending on contract requirements.
- Annual affirmation with full assessment every 3 years.
- POA&Ms permitted for certain requirements.
Level 3 – Expert
- Includes all Level 2 practices plus enhanced security controls aligned with NIST SP 800-172.
- Designed to protect CUI from advanced persistent threats (APTs).
- Government-led assessment every 3 years.
- Annual affirmation required.
Assessment & Certification Process
CMMC ensures that organizations meet a defined level of cybersecurity maturity before being awarded a DoD contract. The required level is specified in each solicitation based on information sensitivity and program risk.
- Self-Assessments: Required for Level 1 and allowed for certain Level 2 contracts.
- C3PAO Assessments: Independent assessments for sensitive Level 2 environments.
- Government Assessments: Required for Level 3 certification.
A phased rollout introduces CMMC requirements gradually. Contractors are strongly encouraged to prepare early to avoid delays during contract award cycles.
Plans of Action & Milestones (POA&Ms)
POA&Ms are allowed for Level 2 and Level 3 certifications when certain requirements are not fully implemented at the time of assessment. Organizations must close POA&Ms within a defined timeline and complete follow-up verification.
Level 1 does not allow POA&Ms — all practices must be met at the time of assessment.
Implementation Timeline & Phased Rollout
CMMC implementation is being introduced in phases over several years. Each phase adds requirements into DoD solicitations, from self-assessments to full third-party and government-led certification.
Contractors should assess readiness early to ensure they are eligible for future solicitations.
What Your Organization Should Do Now
- Identify whether you handle FCI or CUI.
- Determine which CMMC level aligns with your contract goals.
- Complete a readiness gap assessment against CMMC/NIST requirements.
- Develop or update System Security Plans (SSPs) and required policies.
- Implement technical and procedural remediation steps.
- Adopt tools that streamline evidence gathering and continuous compliance.
