Question 1

Is there a truly free CMMC assessment tool?

Accepted Answer

CMMCTrack Level 1 is the only hosted, no-setup option that is genuinely free with no credit card required. It covers all 15 Level 1 practices under FAR 52.204-21 and tracks your responses with a completion summary and gap list. Reference sites like LayerLogix and cmmcnist.tools are free but are lookup tools, not assessment workflows. Spreadsheets are free but require you to manage the logic yourself, and getting the Level 2 SPRS formula right is harder than it looks.

Question 2

Are open-source tools safe for a real CMMC assessment?

Accepted Answer

It depends on what you mean by safe. Open-source repos can produce useful draft documents, but they are not validated against the DoD Assessment Methodology. An assessor or contracting officer reviewing your submission will check the methodology and scoring, not the tool you used to generate the output. The risk is accuracy, not security. SPRS scoring has specific rules including critical practice exclusions and partial credit for exactly two practices. A spreadsheet or script that gets these wrong produces a score that will not hold up under review.

Question 3

Can a local LLM score CMMC accurately?

Accepted Answer

Not reliably. Large language models are useful for generating draft policy language and remediation plans, but they are not reliable on the specific scoring rules in the DoD Assessment Methodology v1.2.1. The methodology includes practice-specific point weights, partial credit exceptions for exactly two practices (3.5.3 and 3.13.11), and a set of practices that are ineligible for POA&M deferrals. A local LLM will often get the narrative directionally right but the arithmetic wrong. For a score you intend to submit to SPRS, use a tool built on the official methodology.

Question 4

When should I pay instead of using free tools?

Accepted Answer

Free tools are the right starting point for most small contractors. Pay only when the work gets repeatable or the stakes go up. Specific triggers: you are managing more than one client or entity; you need a defensible SPRS score for a live Level 2 contract; you want AI-drafted POA&M plans instead of writing them from scratch; or you are working toward a Level 2 certification and need to track 110 practices with full scoring. CMMCTrack free Level 1 covers the FAR 52.204-21 baseline; Level 2 is $199 one-time and assessor portfolio management is $599 per month.
