A ISO 27018:2019 to ISO 27017:2015 crosswalk, built to order
The table above lists candidate mappings. A crosswalk answers the narrower question you are probably here for: which ISO 27017:2015 controls your existing ISO 27018:2019 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.

- 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 27% in the header counts how many ISO 27018:2019 controls carry at least one candidate mapping in the graph, before any review. The crosswalk percentage counts something stricter: how many ISO 27017:2015 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 27018:2019 and ISO 27017:2015?
ISO 27018:2019 has 84 controls across its framework, while ISO 27017:2015 covers 41 controls. Direct mapping analysis identifies 23 overlapping controls (27% coverage). The frameworks diverge most significantly in Access control – ISO 27018:2019, where 12 ISO 27018:2019 controls have no direct ISO 27017:2015 equivalent.
How many controls map between ISO 27018:2019 and ISO 27017:2015?
Of 84 total ISO 27018:2019 controls, 23 map directly to ISO 27017:2015 controls, representing 27% coverage. The remaining 61 controls represent compliance gaps requiring additional documentation or compensating controls to satisfy both frameworks simultaneously.
What are the compliance gaps when mapping ISO 27018:2019 to ISO 27017:2015?
61 ISO 27018:2019 controls have no direct equivalent in ISO 27017:2015. The highest concentration of gaps is in Access control – ISO 27018:2019 with 12 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 27018:2019 and ISO 27017:2015?
The domain with the highest gap count is Access control – ISO 27018:2019 (12 gaps). Export the full domain-by-domain gap breakdown via the Professional tier to generate a prioritised remediation roadmap.
