According to the TheArtOfService Compliance Knowledge Graph:
ISO 27018:2019 maps to ISO/SAE 21434 with 14% coverage across 12 directly mapped controls. Analysis of 84 ISO 27018:2019 controls identifies 72 compliance gaps, primarily concentrated in Access control – ISO 27018:2019.

A ISO 27018:2019 to ISO/SAE 21434 crosswalk, built to order
The table above lists candidate mappings. A crosswalk answers the narrower question you are probably here for: which ISO/SAE 21434 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 14% 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/SAE 21434 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/SAE 21434?
ISO 27018:2019 has 84 controls across its framework, while ISO/SAE 21434 covers 50 controls. Direct mapping analysis identifies 12 overlapping controls (14% coverage). The frameworks diverge most significantly in Access control – ISO 27018:2019, where 13 ISO 27018:2019 controls have no direct ISO/SAE 21434 equivalent.
How many controls map between ISO 27018:2019 and ISO/SAE 21434?
Of 84 total ISO 27018:2019 controls, 12 map directly to ISO/SAE 21434 controls, representing 14% coverage. The remaining 72 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/SAE 21434?
72 ISO 27018:2019 controls have no direct equivalent in ISO/SAE 21434. The highest concentration of gaps is in Access control – ISO 27018:2019 with 13 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/SAE 21434?
The domain with the highest gap count is Access control – ISO 27018:2019 (13 gaps). Export the full domain-by-domain gap breakdown via the Professional tier to generate a prioritised remediation roadmap.
