The CMMC 2.0 to ISO 27701:2019 crosswalk
The table above lists candidate mappings. A crosswalk answers the narrower question you are probably here for: which ISO 27701:2019 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.
34 of 108 ISO 27701:2019 controls are evidenced by work you have already done for CMMC 2.0. 74 are genuine gaps.
A sample of what the report says
Both require the system boundary and operating environment to be determined and documented.
Grounded in CA.L2-3.12.4 System Security Plan. Confidence high, survived the refutation pass.
Every requirement of ISO/IEC 27001 that speaks of information security must be read as extending to the protection of privacy as it may be affected by the processing of personally identifiable information, so the management system is...
Every one of the 34 evidenced controls and 74 gaps in the report carries this much reasoning, so you can check the claim rather than take it on trust.
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.

- Every gap, with what it requires
- Its level of review stated plainly, not a bare number
Why this page shows two different percentages. The 73% 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 27701:2019 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 27701:2019?
CMMC 2.0 has 110 controls across its framework, while ISO 27701:2019 covers 108 controls. Direct mapping analysis identifies 80 overlapping controls (73% coverage). The frameworks diverge most significantly in System and Communications Protection, where 6 CMMC 2.0 controls have no direct ISO 27701:2019 equivalent.
How many controls map between CMMC 2.0 and ISO 27701:2019?
Of 110 total CMMC 2.0 controls, 80 map directly to ISO 27701:2019 controls, representing 73% coverage. The remaining 30 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 27701:2019?
30 CMMC 2.0 controls have no direct equivalent in ISO 27701:2019. The highest concentration of gaps is in System and Communications Protection with 6 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 27701:2019?
The domain with the highest gap count is System and Communications Protection (6 gaps). Export the full domain-by-domain gap breakdown via the Professional tier to generate a prioritised remediation roadmap.
