CMMC 2.0vsISO 27001:2022
See exactly how CMMC 2.0 controls map to ISO 27001:2022. Pre-computed mappings, identified gaps, and coverage analysis.
A reviewed coverage crosswalk for this pair is available. See which ISO 27001:2022 controls you already evidence.
According to the TheArtOfService Compliance Knowledge Graph:
CMMC 2.0 maps to ISO 27001:2022 with 98% coverage across 108 directly mapped controls. Analysis of 110 CMMC 2.0 controls identifies 2 compliance gaps, primarily concentrated in System and Communications Protection.

The CMMC 2.0 to ISO 27001:2022 crosswalk
The table above lists candidate mappings. A crosswalk answers the narrower question you are probably here for: which ISO 27001:2022 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.
Coverage does not run both ways. CMMC 2.0 into ISO 27001:2022 lands at 49.5%, while ISO 27001:2022 into CMMC 2.0 lands at 79.1%, 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 CMMC 2.0 evidence buys you for ISO 27001:2022, the other asks the reverse.
46 of 93 ISO 27001:2022 controls are evidenced by work you have already done for CMMC 2.0. 47 are genuine gaps.
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.
- 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 98% 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 ISO 27001:2022 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 ISO 27001:2022?
CMMC 2.0 has 110 controls across its framework, while ISO 27001:2022 covers 93 controls. Direct mapping analysis identifies 108 overlapping controls (98% coverage). The frameworks diverge most significantly in System and Communications Protection, where 2 CMMC 2.0 controls have no direct ISO 27001:2022 equivalent.
How many controls map between CMMC 2.0 and ISO 27001:2022?
Of 110 total CMMC 2.0 controls, 108 map directly to ISO 27001:2022 controls, representing 98% coverage. The remaining 2 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 ISO 27001:2022?
2 CMMC 2.0 controls have no direct equivalent in ISO 27001:2022. The highest concentration of gaps is in System and Communications Protection with 2 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 ISO 27001:2022?
The domain with the highest gap count is System and Communications Protection (2 gaps). Export the full domain-by-domain gap breakdown via the Professional tier to generate a prioritised remediation roadmap.
