A major shift has arrived for defense contractors. On November 10, 2025, the Department of Defense finalized the 48 CFR update, officially integrating CMMC 2.0 into DFARS. For contractors handling Controlled Unclassified Information (CUI), the rule introduces new enforceable cybersecurity requirements that include verified compliance through CMMC assessments. 

During this month’s MAD Security Cybersecurity Town Hall, hosts Adam Starnes and Jaclyn Jones explained how the new rule affects organizations across the Defense Industrial Base. They discussed what the changes mean for contract eligibility, NIST 800-171 requirements, and the path to achieving CMMC assessment readiness. 

Key Takeaways from the November Town Hall

48 CFR Final Rule Makes CMMC 2.0 Official

The 48 CFR update now formally requires CMMC Level 2 certification for contractors that handle CUI. This marks the end of the voluntary preparation phase and the beginning of mandatory compliance. 

  • Effective immediately as of November 10, 2025
  • Full certification required by November 2026
  • Some contracts may require certification earlier than federal deadlines 

SPRS Scoring and Affirmation Requirements

The Supplier Performance Risk System (SPRS) now requires detailed scoring for all 110 NIST 800 171 controls. Organizations must provide documentation that supports their scores. Unsubstantiated or inaccurate submissions may result in False Claims Act liability or contract loss. 

  • Minimum score of 88 required to submit an affirmation
  • Organizations must retain documentation supporting each control
  • SPRS scores now influence CMMC assessment readiness and contract awards 

Prime Contractors Are Enforcing Compliance Early

Prime contractors have begun requiring subcontractors to show proof of CMMC progress. This includes SPRS scores, System Security Plans, POAMs, and remediation timelines. 

  • Primes remain responsible for CUI flow down
  • Many primes are using internal deadlines earlier than 2026
  • Subcontractors who cannot show progress may lose opportunities 

Start with a CMMC Gap Assessment

A CMMC Level 2 Gap Assessment is the most effective starting point. It evaluates current controls, identifies deficiencies, and creates a roadmap for remediation and assessment preparation. 

  • MAD’s assessments include seven key deliverables including SSP and POAM
  • Control evidence is prepared in alignment with CMMC assessment expectations
  • Gap assessments help organizations demonstrate progress to primes and internal leadership 

Partner with a Certified MSSP 

Interpreting control requirements can be challenging. MAD Security provides guidance through its Virtual Compliance Manager (VCM) program, which supports organizations through remediation, documentation, and CMMC assessment preparation. Our experts participate with clients during their C3PAO assessment sessions to help ensure clarity and accuracy. 

  • Support is provided by the same professionals who passed MAD’s own CMMC assessment
  • Assistance includes control interpretation, evidence development and planning
  • The combination of technical and compliance leadership increases assessment success rates
