Search for CMMC software and you will find a wall of tools, many of them promising compliance made easy. The honest way to choose is to understand the categories on the market, what each one actually does for you, and which questions expose the difference.
The Four Categories of CMMC Tooling
1. Spreadsheets and DIY templates
Free or cheap. You get a list of 110 controls and the privilege of doing all of the work yourself. Viable only if you have in-house security expertise and more time than money, and keeping evidence current by hand is the part that gets harder every cycle.
2. Generic GRC compliance software
The big category. These tools give you dashboards, control checklists, task assignments, and document storage. Useful, but understand what you are buying: in many of these tools, the software tracks the work while your people still do the work. The gap analysis, the System Security Plan, the policy drafting, the evidence collection, that is still your staff or your consultant, at your cost. A dashboard does not write an SSP.
3. Consultant-led engagements with a portal
High-touch. You get a consultant’s expertise, often billed by the hour, and quality depends on the individual consultant.
4. Agent-as-a-Service (AaaS) providers
The newer category, built for how this problem actually behaves. An AaaS platform does not hand you a checklist. It does the systematic work itself: runs the gap analysis against the 110 NIST SP 800-171 controls, drafts and maintains the SSP and POA&M, maps and packages evidence every cycle, and delivers the results to your team for review and approval. Your people make every decision, and the agents handle the repetitive hours. That is the model ai4cmmc.ai is built for.
Traditional Software vs an AaaS Platform
The categories are easiest to compare on what they take off your team's plate.
| Dimension | Generic GRC software | AaaS platform |
|---|---|---|
| Gap analysis | You run it against a checklist | Platform runs it against all 110 controls |
| SSP and POA&M | Your staff or consultant authors | Drafted and maintained by the platform, your team approves |
| Evidence | You upload and organize | Mapped and packaged every cycle |
| Human role | Generate the content | Review and approve the content |
| Cost driver | Often a per-seat license plus your labor | A fixed subscription price per tier, not a seat license |
The Evaluation Checklist
Whatever you shortlist, ask these questions:
- Does it do work, or track work? Ask the vendor to show you an SSP their platform produced. If the answer is a template, it is a tracker.
- Is evidence collection automated, and how often does it re-measure? Ask for the actual schedule, and what the platform does when something changes between assessments.
- Is there a complete audit trail? Every change, approval, and affirmation logged. Your annual affirmation under 32 CFR 170.22 is a representation to the federal government, so you want receipts behind it.
- Is a human in the loop on every decision? Automation without human approval gates is a liability, not a feature. The right architecture is AI does the work and your people approve it.
- Does it handle CUI appropriately? Ask where data lives and what the platform's own security posture is. A compliance tool that cannot articulate its own boundary is a red flag.
- Does the cost model scale with value or with hours? Hourly models bill more hours when the work runs long. A fixed subscription price does not change with the hours the work takes.
Why the Category Matters More Than the Logo
Many CMMC software comparisons argue about features within the generic GRC category: which dashboard is prettier. That is the wrong debate. The work behind CMMC is labor: analysis, documentation, evidence, upkeep. A tool that tracks that labor leaves it with your team. A platform that performs the recurring part of it, with your team reviewing and approving, takes it off their plate. Compare categories first, vendors second.
DoD’s own numbers are labor numbers. Per the DoD CMMC Program Regulatory Impact Analysis, a small entity’s three-year Level 2 Certification cost of $104,670 breaks down into $20,699 to plan and prepare, $76,743 to conduct the assessment (the C3PAO’s engagement at $31,234 plus $45,509 of the contractor’s own director and external service provider hours), $2,851 to report results and $4,377 for affirmations. Every line is estimated as hours times labor rates, and DoD assumed the NIST SP 800-171 requirements were already implemented, so implementation and remediation are not in these figures. Planning, evidence and documentation are the part of that work an AaaS platform is designed to help with; the C3PAO’s assessment is not.

The Short Version
- Have expertise and time? DIY is possible. Painful, but possible.
- Want organization? Generic GRC software will organize the work you still have to do.
- Want the systematic work done for you? An AaaS platform does the analysis, documentation and evidence work, and your team reviews and approves it.
Test the difference yourself. See your gap analysis first, then decide whether you would rather have had a dashboard. For more on the cost side, read what the DoD estimated CMMC Level 2 certification costs.
