The Department of War, in finally requiring Cybersecurity Maturity Model Certification (CMMC) 2.0 implementation, has made cybersecurity a contractual requirement, not a best practice. Companies across the defense industrial base are now facing a new reality: without demonstrable cybersecurity maturity, they are ineligible for substantive DoD awards.
The first question many companies ask is whether CMMC applies to them. That means understanding what information the business handles, reviewing DFARS clauses embedded in contracts, and evaluating likely future solicitations. The short answer is that if your organization does business with the Department of War, it likely does, with the starting point as clarity on scope. Prime contractors and subcontractors that handle Federal Contract Information (FCI) or Controlled Unclassified Information (CUI) fall squarely within scope, requiring full evaluation of their supply chains. This includes manufacturers, engineering firms, IT providers, professional services firms, and even small specialty subcontractors supporting larger primes. Companies that never directly contract with the DoD but receive CUI through a supply chain relationship may also be required to meet Level 2 standards. As CMMC language is inserted into new solicitations and follow-on acquisitions, compliance will increasingly determine eligibility, not just competitiveness.
CMMC 2.0 streamlines the original five-level framework into three tiers aligned with existing federal standards. Level 1 covers foundational safeguarding of FCI and requires annual self-assessments, essentially table stakes. Level 2 aligns with NIST SP 800-171 and applies to companies handling CUI; depending on contract sensitivity, this may require either self-assessment or third-party certification. Level 3, reserved for contractors supporting critical national security programs, builds on NIST SP 800-172 and requires government-led assessments. For most companies operating in today’s defense market, Level 2 is the focal point and the new baseline.
Although CMMC implementation is phased, contractors handling CUI previously were already expected under the initial rollout to complete NIST SP 800-171 self-assessments and submit scores into the Supplier Performance Risk System (SPRS). Outdated or missing SPRS scores can delay or prevent contract awards, meaning organizations that have not completed this step are operating at a competitive disadvantage and should urgently address.
Beyond award eligibility, enforcement risk is increasingly material. The Department of Justice’s Civil Cyber-Fraud Initiative has made clear that inaccurate cybersecurity attestations can trigger False Claims Act exposure. Because senior officials are required to affirm the accuracy of SPRS submissions and CMMC certifications, deficiencies are no longer confined to technical remediation—they may create legal and fiduciary risk. Treble damages, reputational impact, and potential suspension or debarment are not theoretical outcomes. As enforcement mechanisms mature, cybersecurity compliance is moving from a procurement checklist to an enterprise risk issue requiring board-level oversight.
Many contractors discover gaps in their implementation of required controls. In those cases, Plans of Action and Milestones (POA&Ms) could be developed to document remediation timelines. Under CMMC 2.0, limited POA&Ms are permitted but cannot cover certain high-priority requirements and must be resolved within defined periods. The direction of travel is clear: documented intent is no longer enough; demonstrable implementation is required.
In practice, most organizations benefit from conducting a refreshed gap assessment aligned specifically to CMMC 2.0. While many contractors previously assessed against NIST 800-171, CMMC places greater emphasis on evidence and institutionalization. Remediation efforts often extend beyond incremental IT improvements. Multi-factor authentication, access controls, incident response testing, configuration management, and audit log review processes are frequently cited areas requiring additional rigor. Companies are investing in stronger identity and access management tools, endpoint detection and response systems, centralized logging capabilities, and more formalized governance processes. Documentation maturity is equally critical—policies must reflect operational reality and consistent implementation—and executive engagement is essential. CMMC compliance cannot be delegated entirely to IT departments; an effective program requires leadership ownership, budget alignment, and cross-functional coordination.
Third-party assessments, often required, are now the limiting factor and a choke point in the system, and preparation increasingly resembles an audit. Organizations are conducting internal readiness reviews, validating that evidence is readily retrievable, and ensuring that employees understand both policy and practice. Consistency across departments is vital, as assessors evaluate not only technical safeguards but also how well cybersecurity practices are embedded in daily operations. Supply chain exposure remains one of the most significant emerging risks. Cyber vulnerability at a subcontractor can disrupt an entire program. Leading contractors are mapping subcontractor data flows, updating contractual language, and incorporating cybersecurity posture into diligence processes. Cyber risk has become program risk.
The economic implications extend beyond compliance budgets. Achieving and maintaining CMMC readiness requires sustained investment in tooling, documentation, third-party assessment, and internal governance capacity. For well-capitalized firms, these costs may be absorbed as a necessary operating expense and even leveraged as a competitive differentiator. For smaller contractors and specialty subcontractors, however, the burden may compress margins or constrain participation in certain programs. This dynamic is likely to accelerate stratification within the defense industrial base, favoring organizations with institutionalized controls and disciplined capital planning. Cyber maturity is becoming a structural barrier to entry—not only a regulatory requirement.
The broader implications are strategic. CMMC compliance raises the barrier to entry in the defense market and also offers a competitive advantage in dual use and commercial offerings. Firms that fail tomeet requirements will simply be excluded from certain awards. For investors and capital partners, cybersecurity posture now influences valuation, risk assessment, and exit planning. A contractor with mature, well-documented controls presents less diligence friction and lower operational risk.
While CMMC 2.0 simplifies the prior framework, it does not reduce expectations. The Department of War has signaled sustained commitment to enforcing cybersecurity standards across the industrial base. Contractors that move early, invest thoughtfully, and treat compliance as an operational capability rather than a regulatory burden will be positioned to compete effectively.
At Arsenal Enterprise Capital, we view cybersecurity readiness as integral to building scalable, mission-critical defense businesses. In the current environment, CMMC compliance is not simply about passing an assessment. It is about protecting eligibility, strengthening enterprise value, and demonstrating resilience in a market where trust and security are paramount.
