CMMC 2.0vsNIST SP 800-172
See exactly how CMMC 2.0 controls map to NIST SP 800-172. 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 800-172 with 45% coverage across 50 directly mapped controls. Analysis of 110 CMMC 2.0 controls identifies 60 compliance gaps, primarily concentrated in Access Control.

The CMMC 2.0 to NIST SP 800-172 crosswalk
The table above lists candidate mappings. A crosswalk answers the narrower question you are probably here for: which NIST SP 800-172 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.
20 of 110 CMMC 2.0 controls are evidenced by work you have already done for NIST SP 800-172. 90 are genuine gaps.
A sample of what the report says
Restricting access to only organization owned, provisioned or issued resources controls external system connections.
Grounded in 3.1.2e Restrict Access to Organization-Owned, Provisioned, or Issued Information Resources. Confidence high, survived the refutation pass.
Restrict system access so only identified, authorized users, the processes running on their behalf, and approved devices including other connected systems can connect.
Every one of the 20 evidenced controls and 90 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 45% 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 800-172 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 800-172?
CMMC 2.0 has 110 controls across its framework, while NIST SP 800-172 covers 35 controls. Direct mapping analysis identifies 50 overlapping controls (45% coverage). The frameworks diverge most significantly in Access Control, where 14 CMMC 2.0 controls have no direct NIST SP 800-172 equivalent.
How many controls map between CMMC 2.0 and NIST SP 800-172?
Of 110 total CMMC 2.0 controls, 50 map directly to NIST SP 800-172 controls, representing 45% coverage. The remaining 60 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 800-172?
60 CMMC 2.0 controls have no direct equivalent in NIST SP 800-172. The highest concentration of gaps is in Access Control with 14 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 800-172?
The domain with the highest gap count is Access Control (14 gaps). Export the full domain-by-domain gap breakdown via the Professional tier to generate a prioritised remediation roadmap.
