CMMC Nears Reality: Cyber Readiness or Contracting Roadblock for Small Businesses?
After years of debate, delays, and revisions, the Department of Defense’s Cybersecurity Maturity Model Certification (CMMC) is officially moving from theory to enforcement. The final CMMC 2.0 rule dropped in October 2024, and as of January 2025, DFARS clause 252.204-7021 is live. That means starting October 1, 2025, every new DoD contract—except for COTS-only buys—will carry mandatory CMMC language. For small contractors, this is no longer a “someday” compliance issue. It’s here, and it’s expensive.
What Changed: The Timeline Gets Real
The CMMC rule is final as of October 2024.
DFARS compliance clause became effective in January 2025.
By October 2025, all new DoD solicitations must include CMMC requirements.
Level 1–2 assessments start rolling out in 2025, with full enforcement expected by 2028.
Translation: if you handle Controlled Unclassified Information (CUI) or even basic Federal Contract Information (FCI), you’ll need a certification path mapped out this year.
Why Small Businesses Are Worried
Compliance isn’t cheap. DoD estimates a Level 1 self-assessment costs around $6K annually, while a Level 2 third-party certification runs $100K–$105K every three years. For many small firms, that’s a game-changing budget item. Nationwide, compliance costs could reach $2B for small businesses over 20 years, with $4B in annual recurring costs across the defense industrial base.
Worse, readiness surveys show small firms aren’t close to prepared:
58% of contractors admit they’re not ready or only slightly prepared.
Only 4% say they’re “completely ready.”
56% haven’t done a NIST 800-171 gap analysis.
70% haven’t deployed the required technical solutions.
And compliance doesn’t stop with primes. Flow-down requirements mean subcontractors touching CUI must also meet CMMC standards. No more flying under the radar—if your prime needs Level 2 or higher, you’re on the hook too.
Industry Pushback vs. DoD’s Firm Stance
DoD insists CMMC isn’t introducing “new” requirements but enforcing existing cybersecurity rules. They emphasize that CMMC 2.0 aligns directly with NIST standards and that assistance programs like APEX Accelerators, NCODE enclaves, and Mentor-Protégé are available to help.
Still, trade groups like PSC and NDIA are blunt: costs, staffing shortages, and limited availability of third-party assessors could choke out small business participation. Even the SBA’s Office of Advocacy has warned that without more flexibility, compliance could become a barrier to entry for thousands of small firms.
What This Means for You
If you’re a small contractor—or a sub in a prime’s supply chain—ignoring CMMC isn’t an option. DoD is clear: no certification, no contract. That risk extends beyond new awards. Some firms already report losing bids due to unmet cybersecurity standards. Agencies are under pressure to secure data, and primes are demanding compliance from subs to protect themselves.
Action Plan for Small Contractors
Assess Now, Don’t Wait
Run a gap analysis against NIST 800-171 controls. Even if you can’t fix everything immediately, knowing where you stand helps you prioritize.Use Free DoD Resources
Leverage the DIB CSaaS portal, APEX Accelerators, and DoD training events. They exist to lower the cost curve for small firms.Talk to Your Primes
If you’re a subcontractor, work with your prime to isolate CUI in enclaves. Ask about shared resources or equitable adjustments for compliance costs.Strengthen the Basics
At a minimum, deploy multifactor authentication, encryption, patch management, and an incident response plan. Many small firms fail audits simply due to missing documentation.Budget for Certification
Whether outsourcing IT security or hiring a C3PAO for a pre-assessment, build these costs into your pricing strategy now.Market Your Readiness
If you achieve Level 1 or Level 2 early, flaunt it. Being CMMC-ready isn’t just compliance—it’s a selling point. Agencies and primes will see you as a safer bet.
Big Picture
CMMC is both a burden and an opportunity. Yes, the costs and complexity are real, and some small businesses may choose to walk away from DoD work altogether. But those who invest in compliance will gain a competitive edge in a shrinking field. With DoD doubling down on cybersecurity, being “CMMC-ready” could be the difference between being cut from the defense supply chain—or becoming a trusted partner that agencies and primes seek out.
