CMMC 2.0vsNIST SP 800-218
See exactly how CMMC 2.0 controls map to NIST SP 800-218. 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 800-218 with 15% coverage across 16 directly mapped controls. Analysis of 110 CMMC 2.0 controls identifies 94 compliance gaps, primarily concentrated in Access Control.

The CMMC 2.0 to NIST SP 800-218 crosswalk
The table above lists candidate mappings. A crosswalk answers the narrower question you are probably here for: which NIST SP 800-218 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.
8 of 110 CMMC 2.0 controls are evidenced by work you have already done for NIST SP 800-218. 102 are genuine gaps.
A sample of what the report says
Role appropriate secure development training is delivered, tracked and refreshed.
Grounded in SP800-218-PO.2.2 Training and Skills Maintenance. 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 8 evidenced controls and 102 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 15% 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 800-218 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 800-218?
CMMC 2.0 has 110 controls across its framework, while NIST SP 800-218 covers 42 controls. Direct mapping analysis identifies 16 overlapping controls (15% coverage). The frameworks diverge most significantly in Access Control, where 21 CMMC 2.0 controls have no direct NIST SP 800-218 equivalent.
How many controls map between CMMC 2.0 and NIST SP 800-218?
Of 110 total CMMC 2.0 controls, 16 map directly to NIST SP 800-218 controls, representing 15% coverage. The remaining 94 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 800-218?
94 CMMC 2.0 controls have no direct equivalent in NIST SP 800-218. The highest concentration of gaps is in Access Control with 21 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 800-218?
The domain with the highest gap count is Access Control (21 gaps). Export the full domain-by-domain gap breakdown via the Professional tier to generate a prioritised remediation roadmap.
