The final 48 CFR rule makes CMMC (Cybersecurity Maturity Model Certification) real for contractors. If you touch Federal Contract Information (FCI) or Controlled Unclassified Information (CUI), this affects you. With the Federal Register document from September 10, 2025, providing clear implementation timelines, here's what LA contractors need to do now to stay compliant and competitive.
What You'll Learn in This Guide
What the Final 48 CFR Rule Means
The final rule codifies CMMC requirements into federal acquisition regulations. This isn't optional guidance—it's mandatory law for all DoD contractors.
Legal Requirement
The 48 CFR rule makes CMMC compliance a legal requirement, not just a best practice. Non-compliance can result in contract termination and False Claims Act exposure.
Scope of Coverage
All DoD contractors handling FCI or CUI must comply. This includes manufacturers, machine shops, engineering firms, service providers, and subcontractors.
Assessment Requirements
Level 2 and above require third-party assessments by certified assessors. Self-attestation is no longer sufficient for CUI contracts.
Federal Register Implementation Timeline
The September 10, 2025 Federal Register document provides clear deadlines that contractors must meet. Understanding these timelines is critical for planning.
Phase 1: Immediate Requirements (October 2025)
All new DoD contracts issued after October 1, 2025, require CMMC Level 1 certification at minimum. Existing contractors have until December 31, 2025, to achieve Level 1 compliance.
Phase 2: CUI Requirements (January 2026)
Contracts involving Controlled Unclassified Information (CUI) require CMMC Level 2 certification starting January 1, 2026. Contractors have a 12-month grace period to achieve compliance.
Phase 3: Full Implementation (January 2027)
By January 1, 2027, all DoD contractors must have achieved their required CMMC level. No exceptions or extensions will be granted after this date.
Assessment Scheduling
Plan for 3-6 months to prepare for assessment, plus 2-4 weeks for the actual assessment process. Start preparation at least 6 months before your contract renewal date.
CMMC Levels Explained
Understanding which level you need is crucial for proper planning and budgeting.
Level 1: Basic Cyber Hygiene
Required for contracts with Federal Contract Information (FCI). Includes 17 basic security practices like antivirus software, regular backups, and access controls.
Level 2: Intermediate Cyber Hygiene
Required for contracts with Controlled Unclassified Information (CUI). Includes 110 security controls based on NIST SP 800-171 with third-party assessment required.
Level 3: Good Cyber Hygiene
Required for contracts with sensitive information. Includes additional controls for advanced persistent threats and requires third-party assessment.
Levels 4-5: Advanced and Expert
Required for contracts with highly sensitive information. Most contractors won't need these levels unless handling classified information.
Compliance Requirements by Contract Type
Different types of contracts require different CMMC levels. Understanding your requirements helps you plan appropriately.
FCI Contracts
Contracts involving Federal Contract Information require Level 1 certification. This includes basic DoD contract information and non-sensitive data.
CUI Contracts
Contracts involving Controlled Unclassified Information require Level 2 certification. This includes technical data, proprietary information, and other sensitive but unclassified data.
Subcontractor Requirements
Subcontractors must meet the same CMMC requirements as prime contractors for the data they handle. This creates a cascading compliance requirement throughout the supply chain.
Cost and Timeline Planning
Proper planning helps you budget accurately and meet Federal Register deadlines.
Implementation Costs
Level 1: $5,000-$10,000; Level 2: $15,000-$25,000; Level 3: $25,000-$50,000. These costs include technology, consulting, documentation, and training.
Assessment Costs
Assessment fees range from $5,000-$15,000 depending on the level and complexity of your environment. Factor this into your budget planning.
Timeline Planning
Allow 6-12 months total: 3-6 months for implementation, 1-2 months for preparation, 2-4 weeks for assessment. Start planning immediately to meet Federal Register deadlines.
ROI Considerations
While compliance costs money upfront, the ROI comes from maintaining DoD contracts, reduced insurance costs, and competitive advantage in the defense market.

Common Compliance Failures
The top three reasons contractors fail CMMC assessments are missing multifactor authentication, weak backup systems, and poor access controls.
Key Data:
These three controls cause 70% of assessment failures. Addressing them first significantly improves your chances of passing.
