NIST SP 800-171 Rev 3vsCMMC 2.0
See exactly how NIST SP 800-171 Rev 3 controls map to CMMC 2.0. 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:
NIST SP 800-171 Rev 3 maps to CMMC 2.0 with 91% coverage across 88 directly mapped controls. Analysis of 97 NIST SP 800-171 Rev 3 controls identifies 9 compliance gaps, primarily concentrated in 03.17 SR (Supply Chain Risk Management).

The NIST SP 800-171 Rev 3 to CMMC 2.0 crosswalk
The table above lists candidate mappings. A crosswalk answers the narrower question you are probably here for: which CMMC 2.0 controls your existing NIST SP 800-171 Rev 3 work already satisfies, which are real gaps, and the reasoning behind every claim so you can check it. One pair, $299, one time.
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.
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.

Why this page shows two different percentages. The 91% in the header counts how many NIST SP 800-171 Rev 3 controls carry at least one candidate mapping in the graph, before any review. The crosswalk percentage counts something stricter: how many CMMC 2.0 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 NIST SP 800-171 Rev 3 and CMMC 2.0?
NIST SP 800-171 Rev 3 has 97 controls across its framework, while CMMC 2.0 covers 110 controls. Direct mapping analysis identifies 88 overlapping controls (91% coverage). The frameworks diverge most significantly in 03.17 SR (Supply Chain Risk Management), where 3 NIST SP 800-171 Rev 3 controls have no direct CMMC 2.0 equivalent.
How many controls map between NIST SP 800-171 Rev 3 and CMMC 2.0?
Of 97 total NIST SP 800-171 Rev 3 controls, 88 map directly to CMMC 2.0 controls, representing 91% coverage. The remaining 9 controls represent compliance gaps requiring additional documentation or compensating controls to satisfy both frameworks simultaneously.
What are the compliance gaps when mapping NIST SP 800-171 Rev 3 to CMMC 2.0?
9 NIST SP 800-171 Rev 3 controls have no direct equivalent in CMMC 2.0. The highest concentration of gaps is in 03.17 SR (Supply Chain Risk Management) with 3 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 NIST SP 800-171 Rev 3 and CMMC 2.0?
The domain with the highest gap count is 03.17 SR (Supply Chain Risk Management) (3 gaps). Export the full domain-by-domain gap breakdown via the Professional tier to generate a prioritised remediation roadmap.
