ISO 27001:2022vsCMMC 2.0
See exactly how ISO 27001:2022 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:
ISO 27001:2022 maps to CMMC 2.0 with 82% coverage across 76 directly mapped controls. Analysis of 93 ISO 27001:2022 controls identifies 24 compliance gaps, primarily concentrated in Organizational controls – ISO 27001:2022.

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.
A sample of what the report says
Information access restriction enforces the authorised access decision.
Grounded in iso-27001-2022::8.3 Information access restriction. Confidence high, survived the refutation pass.
Authorize each wireless connection before it is permitted to attach to the system.
Every one of the 87 evidenced controls and 23 gaps in the report carries this much reasoning, so you can check the claim rather than take it on trust.
46 of 93 ISO 27001:2022 controls are evidenced by work you have already done for CMMC 2.0. 47 are genuine gaps.
A sample of what the report says
Personnel action safeguards require system related property to be retrieved on termination.
Grounded in PS.L2-3.9.2 Personnel Actions. Confidence high, survived the refutation pass.
Write, approve and publish a top-level security policy plus topic-specific policies, and review them on a set cadence and after major change.
Every one of the 46 evidenced controls and 47 gaps in the report carries this much reasoning, so you can check the claim rather than take it on trust.

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 24 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?
24 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.
