CMMC Compliance, Safeguarding CUI

Defense contractors handling Controlled Unclassified Information (CUI) must achieve CMMC Level 2 compliance to remain eligible for Department of Defense (DoD) contracts as enforcement phases advance into 2026. The Cybersecurity Maturity Model Certification (CMMC) program, effective for new solicitations since November 10, 2025, mandates implementation of 110 security practices from NIST

SP 800-171 for Level 2. Phase 2 enforcement begins November 10, 2026, requiring third-party assessments by Certified Third-Party Assessment Organizations (C3PAOs) for most applicable contracts. Failure to demonstrate verifiable compliance exposes organizations to significant risks, including False Claims Act (FCA) liability under the Department of Justice (DOJ) Civil Cyber-Fraud Initiative, particularly from inaccurate affirmations or certifications that invite whistleblower actions.


This article examines CMMC Level 2 compliance requirements in 2026, the intersection with FCA enforcement, and strategies to mitigate risks through continuous monitoring and accurate reporting.


CMMC Level 2 Requirements in 2026


CMMC Level 2 focuses on advanced protection of CUI, aligning with the 110 controls in NIST SP 800-171 Rev 2 across 14 domains, including access control, audit and accountability, configuration management, identification and authentication, incident response, maintenance, media protection, personnel security, physical protection, risk assessment, security assessment, system and communications protection, system and information integrity, and awareness and training.


Contractors must:


  • Achieve a minimum score of 88 out of the 110-point scoring scale on self-assessments (where permitted) or full third-party certification.

  • Submit assessment results to the Supplier Performance Risk System (SPRS).

  • Obtain annual affirmations from a senior official attesting to full implementation and ongoing maintenance of controls.

  • Maintain current status throughout contract performance, with conditional status allowed for up to 180 days to close Plans of Action and Milestones (POA&Ms).


DoD estimates approximately 80,000 organizations require Level 2 certification, with about 95 percent needing C3PAO assessments. Readiness remains low, with approximately 773 Level 2 certifications issued as of January 2026 Cyber AB town halls (representing under 1 percent of the estimated 80,000 organizations requiring Level 2 certification). Phase 2 mandates third-party verification for most new contracts handling CUI, making preparation essential to avoid bid exclusions or disruptions.


False Claims Act Risks Tied to CMMC Level 2 Compliance


The FCA (31 U.S.C. §§ 3729–3733) imposes liability for knowingly submitting false claims, using false records, or making material false statements to the government. Under the Civil Cyber-Fraud Initiative (launched 2021), DOJ targets cybersecurity misrepresentations, including inaccurate CMMC affirmations or SPRS submissions. No actual breach is required; materiality arises when representations influence contract award, options, or payments.


Fiscal year 2025 saw record FCA recoveries of $6.8 billion, with over $52 million from nine cybersecurity cases. Qui tam whistleblower filings reached 1,297, the highest on record, with relators receiving 15 to 30 percent of recoveries. Insiders, such as IT staff or compliance personnel, are positioned to identify gaps between affirmed status and actual controls.


Deputy Attorney General Lisa O. Monaco, announcing the Civil Cyber-Fraud Initiative in October 2021, stated: “For too long, companies have chosen silence under the mistaken belief that it is less risky to hide a breach than to bring it forward and to report it.” She added: “We are announcing today that we will use our civil enforcement tools to pursue companies, those who are government contractors who receive federal funds, when they fail to follow required cybersecurity standards — because we know that puts all of us at risk.”


Acting Assistant Attorney General Brett A. Shumate of the Justice Department’s Civil Division, in a 2025 settlement context, emphasized: “We will continue to pursue knowing violations of cybersecurity requirements by federal contractors and grantees to protect Americans’ privacy and economic and national security.”


Recent settlements illustrate risks:


  • MORSECORP Inc. paid $4.6 million in March 2025 for inflated SPRS scores and incomplete NIST SP 800-171 implementation.


  • Raytheon, RTX, and Nightwing Group paid $8.4 million in May 2025 for failures to develop system security plans on 29 DoD contracts, including successor liability.


CMMC's annual affirmations create recurring exposure. An inaccurate affirmation constitutes a false statement material to payments, amplifying FCA risks as third-party validations increase whistleblower visibility.


Whistleblower Exposure in CMMC Level 2 Environments


The FCA's qui tam provisions encourage whistleblowers to report violations, with protections against retaliation. In CMMC contexts, discrepancies in control implementation, unsupported affirmations, or unreported gaps can trigger filings. Legal analyses describe this as the "CMMC affirmation trap," where recurring certifications heighten scrutiny compared to prior self-attestations.


Stacy Bostjanick, Chief of Defense Industrial Base Cybersecurity and Deputy Chief Information Officer for Cybersecurity at DoD, has underscored the national security imperative of CMMC compliance. In a 2025 settlement announcement involving Georgia Tech Research Corporation, she stated: “Failure to follow required cybersecurity requirements puts all of us at risk.” She further noted: “Those who knowingly provide deficient cybersecurity products or services, misrepresent their cybersecurity practices or protocols, or violate obligations to monitor and report cybersecurity incidents and breaches must be held accountable.”


In earlier remarks, Bostjanick described CMMC as foundational: “I view CMMC as the roll, before the crawl, before the walk, before the broader implementation.” She has also highlighted past compliance failures, such as vendors using generic templates or unrealistic remediation plans, stating: “We found companies with 25 people using a 500-page template with ‘insert name here,’ and POAMs that extended out to the year 2099. By the letter of the law, they were compliant. But practically, they were nowhere close.”


Contractors face financial penalties (treble damages plus up to $28,619 per false claim in 2025), contract termination, negative past performance ratings, and debarment. Successor liability in acquisitions adds further complexity.


Civil Investigative Demands (CIDs) in CMMC Enforcement


Civil Investigative Demands (CIDs) serve as a powerful early-stage tool in FCA investigations under the Civil Cyber-Fraud Initiative. Issued by the DOJ, CIDs compel production of documents, written responses, and sworn testimony, often before the full scope of allegations is clear. In cybersecurity matters, CIDs frequently demand extensive data spanning multiple years, including emails, records, communications, and evidence of CUI locations and protections.


For defense contractors, CIDs pose significant challenges in hybrid environments where unstructured data is dispersed and CUI boundaries are not always clearly defined. Traditional tools relying on keyword matching often generate excessive false positives or miss context-dependent CUI, complicating rapid, defensible responses. Short timelines increase costs and operational disruption, with non-compliance risking escalation to federal court.


A purpose-built CUI discovery solution addresses these issues by scanning environments against recognized CUI categories, providing explainable results structured for legal review, and enabling precise identification of regulated data. This approach supports accurate responses to CIDs, reduces exposure from gaps between attested compliance and actual implementation, and aligns with DoD expectations for verifiable CUI protection under CMMC.


Mitigation Strategies for CMMC Level 2 Compliance


To address CMMC Level 2 compliance and associated FCA risks:


  • Conduct thorough gap analyses against NIST SP 800-171 and remediate deficiencies with documented evidence.

  • Implement continuous CUI monitoring to ensure controls remain effective and support accurate annual affirmations.

  • Use Teramis.us for scanning environments, identifying CUI, enforcing boundaries, and generating audit-ready reports.

  • Train affirming officials on legal implications and establish internal escalation protocols.

  • Perform regular internal audits and third-party readiness assessments.

  • Consider voluntary self-disclosure for issues, as DOJ credits timely cooperation and remediation.


These measures align with DoD priorities and reduce inadvertent misrepresentations.


Conclusion


CMMC Level 2 compliance in 2026 represents a critical threshold for defense contractors, with Phase 2 enforcement mandating third-party verification and continuous status maintenance. The integration with FCA enforcement under the Civil Cyber-Fraud Initiative means inaccurate affirmations or certifications carry substantial risks, including whistleblower-driven actions and multimillion-dollar settlements. Proactive, evidence-based compliance through continuous monitoring mitigates these exposures and preserves contract eligibility.
