CMMC 2.0vsNIST SP 800-171 Rev 3
See exactly how CMMC 2.0 controls map to NIST SP 800-171 Rev 3. Pre-computed mappings, identified gaps, and coverage analysis.
A reviewed coverage crosswalk for this pair is available. See which CMMC 2.0 controls you already evidence.
According to the TheArtOfService Compliance Knowledge Graph:
CMMC 2.0 maps to NIST SP 800-171 Rev 3 with 97% coverage across 107 directly mapped controls. Analysis of 110 CMMC 2.0 controls identifies 3 compliance gaps, primarily concentrated in System and Communications Protection.

The CMMC 2.0 to NIST SP 800-171 Rev 3 crosswalk
The table above lists candidate mappings. A crosswalk answers the narrower question you are probably here for: which NIST SP 800-171 Rev 3 controls your existing CMMC 2.0 work already satisfies, which are real gaps, and the reasoning behind every claim so you can check it. One pair, $299, one time.
This direction has not been through crosswalk review and sign off, so no coverage figure is published for it. Reporting an unreviewed number would be worse than reporting none. It can be built to order at the same price as a pair that is already on the shelf.
If the two frameworks turn out to have too little in common for a crosswalk to help you, we say so and refund it rather than send a number worth nothing.
104 of 110 CMMC 2.0 controls are evidenced by work you have already done for NIST SP 800-171 Rev 3. 6 are genuine gaps.
A sample of what the report says
Access enforcement records show approved authorizations enforced for logical access to CUI.
Grounded in 03.01.02 Access Enforcement. Confidence high, survived the refutation pass.
Set a minimum complexity for passwords, and require that a newly created password differ in its characters from the one it replaces.
Every one of the 104 evidenced controls and 6 gaps in the report carries this much reasoning, so you can check the claim rather than take it on trust.
- Every evidenced control, with the reasoning behind it
- Every gap, with what it requires
- Its level of review stated plainly, not a bare number
Why this page shows two different percentages. The 97% in the header counts how many CMMC 2.0 controls carry at least one candidate mapping in the graph, before any review. The crosswalk percentage counts something stricter: how many NIST SP 800-171 Rev 3 controls are actually evidenced, after a pass that argued against each mapping and kept only what survived. They answer different questions and they are not meant to agree.
A crosswalk narrows the work. It does not replace an audit, and your assessor may take a different view on individual controls. Mappings between frameworks are judgements, not text printed in either standard, which is why every claim in the report shows its reasoning. Questions go to support@theartofservice.com.

What are the key differences between CMMC 2.0 and NIST SP 800-171 Rev 3?
CMMC 2.0 has 110 controls across its framework, while NIST SP 800-171 Rev 3 covers 97 controls. Direct mapping analysis identifies 107 overlapping controls (97% coverage). The frameworks diverge most significantly in System and Communications Protection, where 2 CMMC 2.0 controls have no direct NIST SP 800-171 Rev 3 equivalent.
How many controls map between CMMC 2.0 and NIST SP 800-171 Rev 3?
Of 110 total CMMC 2.0 controls, 107 map directly to NIST SP 800-171 Rev 3 controls, representing 97% coverage. The remaining 3 controls represent compliance gaps requiring additional documentation or compensating controls to satisfy both frameworks simultaneously.
What are the compliance gaps when mapping CMMC 2.0 to NIST SP 800-171 Rev 3?
3 CMMC 2.0 controls have no direct equivalent in NIST SP 800-171 Rev 3. The highest concentration of gaps is in System and Communications Protection with 2 unmapped controls. These gaps represent areas where additional controls, policies, or documentation must be created to achieve compliance with both frameworks.
Which control domains have the most gaps between CMMC 2.0 and NIST SP 800-171 Rev 3?
The domain with the highest gap count is System and Communications Protection (2 gaps). Export the full domain-by-domain gap breakdown via the Professional tier to generate a prioritised remediation roadmap.
