The ISO 27001:2022 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 ISO 27001:2022 work already satisfies, which are real gaps, and the reasoning behind every claim so you can check it. One pair, $299, one time.
Coverage does not run both ways. ISO 27001:2022 into CMMC 2.0 lands at 79.1%, while CMMC 2.0 into ISO 27001:2022 lands at 49.5%, on the same two control sets. That is not a rounding difference. It is the whole reason these are two separate reports: one asks what your ISO 27001:2022 evidence buys you for CMMC 2.0, the other asks the reverse.
87 of 110 CMMC 2.0 controls are evidenced by work you have already done for ISO 27001:2022. 23 are genuine gaps.
46 of 93 ISO 27001:2022 controls are evidenced by work you have already done for CMMC 2.0. 47 are genuine gaps.

- Every gap, with what it requires
- Its level of review stated plainly, not a bare number
Why this page shows two different percentages. The 82% in the header counts how many ISO 27001:2022 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 ISO 27001:2022 and CMMC 2.0?
ISO 27001:2022 has 93 controls across its framework, while CMMC 2.0 covers 110 controls. Direct mapping analysis identifies 76 overlapping controls (82% coverage). The frameworks diverge most significantly in Organizational controls – ISO 27001:2022, where 7 ISO 27001:2022 controls have no direct CMMC 2.0 equivalent.
How many controls map between ISO 27001:2022 and CMMC 2.0?
Of 93 total ISO 27001:2022 controls, 76 map directly to CMMC 2.0 controls, representing 82% coverage. The remaining 17 controls represent compliance gaps requiring additional documentation or compensating controls to satisfy both frameworks simultaneously.
What are the compliance gaps when mapping ISO 27001:2022 to CMMC 2.0?
17 ISO 27001:2022 controls have no direct equivalent in CMMC 2.0. The highest concentration of gaps is in Organizational controls – ISO 27001:2022 with 7 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 ISO 27001:2022 and CMMC 2.0?
The domain with the highest gap count is Organizational controls – ISO 27001:2022 (7 gaps). Export the full domain-by-domain gap breakdown via the Professional tier to generate a prioritised remediation roadmap.
