On September 10, 2025, the Department of Defense (DoD) published the Cybersecurity Maturity Model Certification (CMMC) 48 CFR Final Rule in the Federal Register. This rule, effective November 10, 2025, makes CMMC compliance a contractual requirement for defense contractors.
If your organization handles Federal Contract Information (FCI) or Controlled Unclassified Information (CUI), understanding CMMC 48 CFR is critical for protecting national security and staying eligible for DoD contracts.
What is CMMC 48 CFR?
The 48 CFR (Code of Federal Regulations) codifies the CMMC 2.0 framework into law. It establishes mandatory cybersecurity requirements for companies in the Defense Industrial Base (DIB).
This rule formalizes how contractors must implement cybersecurity practices, verify compliance, and undergo third-party assessments. Moving forward, CMMC will appear in DoD solicitations and contracts, meaning non-compliance could disqualify you from bidding.
Key Dates and Timeline
- September 10, 2025 – Final rule published in the Federal Register
- November 10, 2025 – Rule becomes effective; Phase 1 roll-out begins
- 2026 and beyond – Gradual integration into all new DoD solicitations and contract renewals
Why CMMC 48 CFR Matters
- Mandatory Compliance: Unlike NIST 800-171 self-attestations, CMMC requires third-party validation for certain levels.
- Competitive Advantage: Compliance demonstrates strong cybersecurity posture, giving you an edge in contract bids.
- Risk Mitigation: Protects sensitive DoD data and reduces liability for breaches.
Preparing for CMMC 48 CFR Compliance
- Conduct a Readiness Assessment – Identify your required CMMC level and map current practices against NIST requirements.
- Perform a Gap Analysis – Document missing controls and prioritize remediation tasks.
- Develop Policies and Documentation – Ensure you have written procedures, SSPs, and POA&Ms.
- Engage a C3PAO – Only Certified Third-Party Assessment Organizations (C3PAOs) are authorized to conduct official CMMC assessments.
- Plan for Budget and Resources – Factor in assessment costs, technology upgrades, and staff training.
Consequences of Non-Compliance
- Ineligibility for DoD contracts
- Breach of contract penalties
- Reputational damage within the defense sector
