What Is a CMMC Gap Assessment and Can You Get One for Free?

If you manufacture products for the Department of Defense, or if your company is part of the defense supply chain, you have probably heard the term CMMC gap assessment. Maybe your prime contractor mentioned it. Maybe you saw it in a contract requirement. Either way, you are probably asking the same question thousands of small manufacturers are asking right now: what exactly is a gap assessment, do I actually need one, and how much is this going to cost me?

The short answer: yes, you likely need one. And no, it does not have to cost you anything. Cyber Grants Alliance offers a fully funded CMMC Gap Assessment Grant for qualifying small and mid-size businesses in the defense industrial base. Here is everything you need to know.

What Is a CMMC Gap Assessment?

A CMMC gap assessment is a structured evaluation of your organization’s current cybersecurity posture measured against the 110 security controls in NIST SP 800-171, which forms the foundation of CMMC Level 2 certification. Not sure whether you need Level 1 or Level 2? See our guide on CMMC Level 1 vs Level 2.

Think of it like a building inspection before you buy a house. The inspector is not there to fix anything. They are there to tell you exactly what is working, what is not, and what needs to be repaired before you can move forward. A gap assessment does the same for your cybersecurity program.

During a gap assessment, a qualified assessor will review:

• Your current IT systems, software, and infrastructure
• How your organization handles Controlled Unclassified Information (CUI)
• Which of the 110 NIST SP 800-171 controls you currently meet
• Which controls have gaps and how significant those gaps are
• A prioritized remediation roadmap to close those gaps

The result is a System Security Plan (SSP) and, in most cases, a Plan of Action and Milestones (POA&M): two documents you will need for your CMMC assessment.

Why Does It Matter Now?

CMMC Phase 2 begins November 10, 2026. DoD contracts will begin requiring CMMC Level 2 certification: not just a self-reported score, but a verified, third-party-assessed certification. If your company handles Controlled Unclassified Information and you do not have your certification in place, you risk losing your ability to bid on or retain DoD contracts.

A gap assessment is step one. You cannot remediate what you have not measured. And you cannot get certified without remediation. The earlier you complete your gap assessment, the more time you have to close your gaps before the November 2026 CMMC deadline.

Can I Really Get a Gap Assessment for Free?

Yes, through Cyber Grants Alliance’s CMMC Gap Assessment Grant program. CGA provides in-kind grants valued at $5,000 each to qualifying small and mid-size businesses in the DIB. The grant covers a comprehensive evaluation against all 110 NIST SP 800-171 security controls, conducted by qualified assessors, at no cost to you.

To qualify, your business generally needs to meet the following criteria:

• You are a small or mid-size business (under 500 employees)
• You hold or expect to hold DoD contracts, or you are a subcontractor in the defense supply chain
• You handle or expect to handle Federal Contract Information (FCI) or Controlled Unclassified Information (CUI)
• You have not yet completed a formal CMMC-aligned gap assessment

Grants are awarded on a first-come, first-served basis. Once available grants for a cycle are allocated, the program closes until the next round of funding.

What Happens After the Gap Assessment?

Once your gap assessment is complete, you will have a clear picture of where you stand. Most small manufacturers find they have gaps; that is completely normal and expected. After your assessment, you may be eligible for additional CGA grant programs including the Pen Testing Grant, Employees Cyber Training Grant, and CyberCert Grant.
