CMMC Compliance
CMMC Title 48 CFR Rule Codification: What Defense Contractors Must Do Now
Think May 26th is just another day? For defense contractors, it marks a critical milestone that could determine your future with the DoD. The Cybersecurity Maturity Model Certification, more specifically the CMMC Final Rule is now officially codified in the Defense Federal Acquisition Regulation Supplement (DFARS) under Title 48, cementing compliance requirements for all defense contracts starting in 2025. to work with the Department of Defense.
No CMMC compliance, no contracts. It’s that simple.
What is CMMC Compliance?
CMMC (Cybersecurity Maturity Model Certification) is the Department of Defense’s comprehensive framework for protecting sensitive defense information. Think of it as a military-grade security clearance for your entire IT infrastructure.
Updated CMMC Compliance Levels
The DFARS Title 48 codification confirms the three-level model established in the Final Rule.A complete breakdown of CMMC 2.0 certification levels showing practice requirements, assessments, and information handling capabilities for each tier
Key Components of CMMC:
- Federal Contract Information (FCI) protection
- Controlled Unclassified Information (CUI) safeguards
- Three distinct compliance levels based on data handling
- Third-party assessment requirements
- Regular recertification processes

CMMC 2025 Deadline: Critical Timeline
The DoD isn’t just suggesting these changes – they’re mandating them. Here’s what you need to know:
- December 16, 2024: CMMC Final Rule took effect
- Early 2025: CMMC requirements begin appearing in contracts
- May 2025: Title 48 of the Code of Federal Regulations (CFR) is codified
- October 2025: Full CMMC implementation expected
- Ongoing: Phased rollout across defense industrial base

Oct 1, 2026Breaking News: CMMC Officially Codified in Federal Regulations
As of April 11, 2025, the CMMC requirements are officially codified in the Defense Federal Acquisition Regulation Supplement (DFARS) under Title 48. This regulatory update transforms CMMC from a pending initiative to enforceable federal law, requiring defense contractors to achieve appropriate certification levels to maintain contract eligibility.
This follows the CMMC Final Rule (32 CFR) that went into effect on December 16, 2024, which established the foundation of the CMMC program itself. The Title 48 codification now confirms the DoD’s commitment to implementing CMMC requirements across all defense contracts beginning in 2025, with the phased rollout continuing through 2028. This marks the final regulatory step before widespread contract inclusion, leaving contractors with a rapidly closing window to achieve compliance.
What This Means for Defense Contractors.
- Contract Requirements Confirmed: CMMC requirements will be included in new contracts and renewals starting in 2025, with phase 1 requiring self-assessment and attestation, while full implementation is expected by 2028
- Certification Timeline Finalized: The typical 12-18 month implementation process means contractors should begin preparation immediately
- Supply Chain Verification: Prime contractors must now verify subcontractor compliance before contract award
- DoD Approval Required: Until September 30, 2025, solicitations and contracts that require specific CMMC levels must be approved by OUSD(A&S)
If you’re anywhere in the defense supply chain, this affects you.

The Strategic Advantage of Early Certification
With CMMC now codified in federal regulations under Title 48 (as of April 11, 2025), contractors face a critical decision: rush compliance later or gain strategic advantage now.
Organizations that achieve certification early will:
- Secure contracts before competitors when CMMC requirements begin appearing in solicitations
- Avoid the assessment backlog (currently 3-6 months)
- Leverage compliance as a competitive differentiator
- Reduce implementation costs through methodical planning
- Establish security as a business enabler rather than a hurdle
The cost of making a mistake here can be the difference between your company running and being out of business. When CMMC Compliance goes in full effect, you are going to see companies go out of business because their contracts will be yanked.

Frequently Asked Questions
How long does CMMC Certification take?
Most organizations need 12-18 months to achieve full certification. The process includes 3-6 months implementing military-grade security controls through our proven implementation framework. Then, as outlined in our maturity requirements guide, you must demonstrate these practices are embedded in your culture - typically requiring 3-6 months of documented operational evidence. Only then can you begin the formal assessment process.
Can I self certify for CMMC?
Self-certification is only available for CMMC Level 1 and requires annual renewal with a senior official affirmation. Our certification requirements guide explains why Level 2 requires third-party assessment from an authorized C3PAO assessor, while Level 3 mandates direct government evaluation. The DoD implemented these stricter requirements after finding only 10-15% of self-assessed companies actually met compliance standards.
Will CMMC requirements be delayed?
No. The Final Rule is published and deadlines are set for 2025.
What happens if you miss the CMMC deadline?
After the Final Rule takes effect December 16, 2024, non-certified contractors lose DoD contracts immediately. Our military-grade compliance solutions ensure you maintain contract eligibility.
How are CMMC assessments different from self-certification?
Third-party CMMC assessments are now mandatory because self-certification proved unreliable - DoD audits found only 10-15% compliance. Review our assessment requirements guide and learn how our C3PAO certification process ensures compliance.
What’s the real difference between CMMC 1.0 and CMMC 2.0?
While CMMC 2.0 reduces levels from five to three, it demands more sophisticated controls than ISO 27001 or HIPAA. See the complete version comparison and learn how our military-grade implementation addresses these elevated requirements.
How does CMMC affect my existing NIST compliance?
CMMC enforces NIST SP 800-171 and 800-172 requirements through verification. Review our NIST compliance guide and see how our Zero Trust architecture streamlines both frameworks.
Do subcontractors need CMMC Certification?
Yes, but our unique approach can help. While flow-down typically requires matching certification levels, our subcontractor compliance guide explains how our Zero Trust architecture can eliminate this requirement.
What’s the CMMC rollout schedule after the Final Rule?
How do you choose between CMMC compliance companies?
Can I meet CMMC security requirements with my current IT team?
Most internal IT teams lack the specialized expertise for CMMC security controls. Our managed IT brings proven security control frameworks that map directly to certification requirements. While basic security tools focus on alerts, we prevent breaches through automated remediation and continuous compliance validation.
What CMMC mistakes should my team look for?
After hundreds of defense contractors achieve certification, we've seen how costly DIY CMMC compliance mistakes can be. The DoD found only 10-15% of self-assessed companies actually met requirements. Learn which mistakes fail certification and how to prevent them.
The most critical errors include:
- Trusting DIY assessments when CMMC deadline 2025 requires expert guidance
- Missing CUI boundary documentation that auditors require for CMMC compliance contractors
- Treating compliance like an annual event instead of continuous monitoring, which the December 16 Final Rule demands
When do DoD CMMC requirements start?
After December 16, 2024, CMMC compliance becomes mandatory for DoD contractors. See critical timeline mistakes contractors make during implementation.
