The Bottom Line Up Front: CMMC Compliance for DoW Contractors
Starting November 10, 2025, the Department of War (DoW) is implementing mandatory cybersecurity requirements that will fundamentally change how defense contractors protect sensitive information. If your company works with the DoW or aspires to win defense contracts, these new Cybersecurity Maturity Model Certification (CMMC) requirements will directly impact your ability to compete and maintain contracts.
What Is CMMC (Cybersecurity Maturity Model Certification), and Why Does It Matter?
The Cybersecurity Maturity Model Certification (CMMC) is the DoW’s new framework for ensuring that defense contractors and subcontractors can adequately protect Federal Contract Information (FCI) and Controlled Unclassified Information (CUI) from cyber threats. With malicious cyber activity costing the U.S. economy between $57 billion and $109 billion annually, the DoW is taking decisive action to secure its defense industrial base (DIB) supply chain.
Unlike previous DFARS 252.204-7012 requirements that relied on self-attestation, CMMC 2.0 introduces third-party verification through certified CMMC Third-Party Assessor Organizations (C3PAOs). This means an independent assessor will verify that your NIST SP 800-171 security controls are actually in place and functioning properly.
Key CMMC Requirements for Defense Contractors and Subcontractors
Immediate CMMC Compliance Actions Required:
- Achieve the Required CMMC Level – Defense contractors must obtain the appropriate CMMC certification level BEFORE contract award
- Maintain CMMC Compliance – Keep your CMMC status current throughout the entire DoW contract lifecycle
- Annual CMMC Affirmations – Complete yearly compliance affirmations in the Supplier Performance Risk System (SPRS)
- Track Your Systems – Provide CMMC unique identifiers (UIDs) for all information systems handling FCI and CUI
- CMMC Flow Down Requirements – Ensure your subcontractors meet appropriate CMMC levels for defense contracts
What Is the 48 CFR Rule?
The 48 CFR rule, formally known as the Defense Federal Acquisition Regulation Supplement (DFARS Case 2019-D041), is the contractual framework that implements CMMC requirements into defense contracts. Published in the Federal Register on September 10, 2025, this rule amends the DFARS to incorporate specific cybersecurity requirements that all defense contractors must meet. It works in conjunction with 32 CFR Part 170 (the technical CMMC requirements) to create a comprehensive cybersecurity framework for the defense industrial base.
Key Elements of the 48 CFR Rule:
- Establishes Contract Clauses – Creates DFARS 252.204-7021 and 252.204-7025, which are the mandatory clauses for CMMC compliance in DoW contracts
- Defines CMMC Status Requirements – Contractors must have current CMMC certification before contract award, not after
- Mandates SPRS Registration – All CMMC assessments and affirmations must be recorded in the Supplier Performance Risk System
- Sets Flowdown Requirements – Prime contractors must ensure subcontractors meet appropriate CMMC levels before sharing FCI or CUI
- Requires Annual Affirmations – Contractors must affirm continuous compliance annually through an authorized official
- Establishes CMMC UIDs – Creates unique identifier system for tracking compliance across multiple contractor information systems
- Excludes COTS Items – Contracts exclusively for commercial off-the-shelf items are exempt from CMMC requirements
- Applies to All Contract Types – Includes FAR Part 12 commercial contracts and applies at all dollar thresholds above micro-purchase
What Is the 32 CFR Rule?
The 32 CFR Part 170 rule, formally titled “Cybersecurity Maturity Model Certification Program,” is the foundational regulation that establishes the CMMC program itself. Published in the Federal Register on October 15, 2024, and effective December 16, 2024, this rule creates the technical framework for cybersecurity assessments across the defense industrial base. It defines the security requirements, assessment procedures, and certification levels that contractors must achieve to handle sensitive government information.
Key Elements of the 32 CFR Rule:
- Establishes CMMC Levels – Defines three certification levels (Level 1 Self-Assessment, Level 2 C3PAO Assessment, and Level 3 DIBCAC Assessment) based on information sensitivity
- Sets Security Requirements – Incorporates NIST SP 800-171 and NIST SP 800-172 controls as the baseline security standards
- Defines Assessment Procedures – Establishes who can conduct assessments (self, C3PAO, or DIBCAC) and validity periods (1 or 3 years)
- Creates POA&M Process – Allows conditional certification with Plans of Action & Milestones for up to 180 days to close minor gaps
- Mandates Annual Affirmations – Requires affirming officials to annually certify continuous compliance with security requirements
- Establishes Scoping Guidance – Defines which assets and systems must be included in CMMC assessments
- Sets Phased Implementation – Creates a 3-year rollout period before full implementation across all DoD contracts
- Defines Information Types – Clarifies requirements for Federal Contract Information (FCI) versus Controlled Unclassified Information (CUI)
CMMC Requirements Impact on Your Defense Contracting Business
CMMC for Prime Defense Contractors:
- Cannot win DoW contracts without the required CMMC certification level
- Must verify subcontractors’ CMMC compliance before flowing down defense contract work
- Responsible for maintaining CMMC compliance throughout the DoW contract period
- Option periods and extensions require current CMMC certification status
CMMC for Defense Subcontractors:
- Some prime contractors have started to require proof of your CMMC certification
- Must maintain your own CMMC compliance independently
- Need to provide CMMC UIDs to prime contractors for DoW contracts
- CMMC requirements flow down through all tiers of the defense supply chain
Common CMMC Compliance Pitfalls to Avoid:
- Waiting Too Long for CMMC Assessment – The C3PAO assessment process can take months; start your CMMC journey now
- Underestimating CMMC Scope – CMMC applies to ALL systems handling FCI and CUI
- Ignoring Subcontractor CMMC Requirements – Their non-compliance becomes your problem
- Letting CMMC Certifications Lapse – Expired CMMC certifications mean lost DoW contracts
- Incomplete CMMC Documentation – Poor record-keeping will fail CMMC assessments
CMMC Cost Impact for Defense Contractors and Small Businesses
The DoW estimates that over 337,000 defense industrial base entities will be impacted by CMMC requirements, with approximately 68% being small businesses. While CMMC compliance costs vary by company size and current NIST SP 800-171 security posture, the cost of CMMC non-compliance is clear: complete exclusion from the defense industrial base.
Consider these CMMC cost factors:
- CMMC assessment preparation costs and readiness activities
- Technology upgrades and cybersecurity tools for NIST SP 800-171 compliance
- CMMC training and personnel costs
- Ongoing CMMC compliance maintenance and annual affirmations
- Potential DoW contract loss if unprepared for CMMC

Why Professional CMMC Consulting Is Critical for Defense Contractors
The CMMC requirements span the DFARS 252.204-7021 clause and 32 CFR Part 170 regulations, totaling hundreds of pages of complex technical and contractual requirements. These regulations require coordination across multiple systems, precise implementation of NIST SP 800-171 technical controls, and understanding of DoW contracting requirements.
A single CMMC compliance oversight can disqualify your company from billions of dollars in defense contracts. Many defense contractors and subcontractors are finding that navigating CMMC compliance requires specialized expertise in:
- Interpreting CMMC regulatory requirements and DFARS clauses
- Implementing NIST SP 800-171 technical security controls
- Preparing for C3PAO third-party assessments
- Managing defense supply chain CMMC compliance
- Maintaining ongoing CMMC certification status
