The High Stakes of CMMC Compliance Failures: Risks You Can’t Afford

In today’s evolving cybersecurity threat landscape, the Department of Defense (DoD) is taking decisive action to ensure that Controlled Unclassified Information (CUI) is protected across the Defense Industrial Base (DIB). The Cybersecurity Maturity Model Certification (CMMC) 2.0 framework has become the gold standard for verifying that defense contractors meet rigorous cybersecurity requirements. And with full enforcement expected by Q3 2025, falling short of CMMC compliance isn’t just a liability—it’s a direct threat to your business.

This blog explores the critical risks associated with poor CMMC compliance, using real-world examples to highlight why staying audit-ready isn’t optional. From contract loss and legal exposure to reputational fallout, here’s what every contractor needs to understand.

1. Contract Termination or Ineligibility to Bid

The most immediate and measurable risk of failing CMMC compliance is losing the right to bid, win, or retain Department of Defense contracts. Per DFARS clause 252.204-7021, contractors must hold a valid CMMC certification at the required level at the time of contract award.

• Level 1 contractors must complete an annual self-assessment and affirm it in the Supplier Performance Risk System (SPRS).

• Level 2 contractors handling CUI must undergo an assessment by a certified CMMC Third-Party Assessor Organization (C3PAO).

  
  

CMMC compliance is not just a checkbox. It is a contractual requirement that applies to both prime contractors and their subcontractors. The lack of a valid certification at the time of award is grounds for disqualification, no matter how qualified or experienced the company may be.

Bottom Line: No CMMC compliance = no contract. Period.

2. False Claims Act Liability and Cybersecurity Misrepresentation

Misrepresenting your CMMC compliance status isn’t just unethical—it’s illegal. Contractors that falsely claim compliance with NIST SP 800-171 or CMMC 2.0 requirements expose themselves to liability under the False Claims Act (FCA). This includes submitting inaccurate SPRS scores or failing to implement required controls while representing to the government that they have.

Real-World Examples:

• MORSECORP Inc. paid $4.6 million in March 2025 to settle allegations of submitting false CMMC compliance claims and SPRS scores.

• In May 2025, Raytheon Companies and Nightwing Group paid $8.4 million in FCA penalties for similar violations tied to cybersecurity non-compliance.

  
  

These cases demonstrate how even major players in the DIB are being held accountable for false attestations. The government and whistleblowers are watching, and the penalties can cripple even large contractors.

Bottom Line: Misrepresenting your CMMC compliance—even unintentionally—can cost millions and damage your credibility with the DoD.

3. Affirmation and Criminal Liability for Senior Leaders

Under the final CMMC rule, every Organization Seeking Certification (OSC) must designate an affirming official to attest to the accuracy of their self-assessment or third-party audit results. This is a legally binding declaration and not a symbolic signature.

The affirming official is personally accountable. If they sign off on false or inaccurate information, they can be prosecuted under 18 U.S. Code § 1001, which criminalizes false statements to the federal government. Inaccurate attestation is also a False Claims Act violation, meaning civil and criminal penalties may apply.

With SPRS now requiring control-by-control attestation across all 110 NIST SP 800-171 requirements, each individual control error could become a separate federal violation.

Bottom Line: CMMC compliance isn't just a team effort—it’s a legal obligation at the executive level.

4. Reputational Damage and Future Opportunity Loss

Even if an organization avoids financial penalties, the reputational consequences of poor CMMC compliance can be devastating. The Supplier Performance Risk System (SPRS) serves as the DoD’s official tool for assessing a contractor’s risk level—including cybersecurity posture.

Failing a C3PAO audit or appearing noncompliant in SPRS may:

• Eliminate future opportunities to bid on sensitive projects.

• Reduce your attractiveness as a subcontractor.

• Damage your standing with prime contractors and integrators.

In the highly competitive defense ecosystem, reputation is everything. Once you’ve been flagged as a risk, it’s difficult to rebuild that trust.

Bottom Line: Poor CMMC compliance history can silently cost your company millions in lost business.

Best Practices to Avoid These Risks

To reduce your organization’s exposure to these risks, follow these core best practices:

• Complete a formal gap analysis against all 110 NIST SP 800-171 controls.

• Update and maintain an accurate System Security Plan (SSP) with clear implementation narratives.

• Track and remediate deficiencies using a documented Plan of Action & Milestones (POA&M).

• Train executives on their legal responsibilities as affirming officials.

• Use secure enclaves and cloud environments that are pre-hardened for CMMC compliance.

Final Thoughts

CMMC compliance is more than a technical checklist—it's a strategic imperative. As enforcement tightens, the risks of inaction or misrepresentation become too great to ignore. From contract loss and multimillion-dollar penalties to executive liability and long-term reputational damage, the consequences of non-compliance are real and rising.
