Need this as a report you can hand to an assessor? A coverage crosswalk for this pair can be built to order.
According to the TheArtOfService Compliance Knowledge Graph:
ISO/SAE 21434 maps to ISO 27018:2019 with 2% coverage across 4 directly mapped controls. Analysis of 164 ISO/SAE 21434 controls identifies 160 compliance gaps, primarily concentrated in Superseded batch representation – ISO/SAE 21434.

A ISO/SAE 21434 to ISO 27018:2019 crosswalk, built to order
The table above lists candidate mappings. A crosswalk answers the narrower question you are probably here for: which ISO 27018:2019 controls your existing ISO/SAE 21434 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.

- Its level of review stated plainly, not a bare number
Why this page shows two different percentages. The 2% in the header counts how many ISO/SAE 21434 controls carry at least one candidate mapping in the graph, before any review. The crosswalk percentage counts something stricter: how many ISO 27018:2019 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 ISO/SAE 21434 and ISO 27018:2019?
ISO/SAE 21434 has 164 controls across its framework, while ISO 27018:2019 covers 82 controls. Direct mapping analysis identifies 4 overlapping controls (2% coverage). The frameworks diverge most significantly in Superseded batch representation – ISO/SAE 21434, where 46 ISO/SAE 21434 controls have no direct ISO 27018:2019 equivalent.
How many controls map between ISO/SAE 21434 and ISO 27018:2019?
Of 164 total ISO/SAE 21434 controls, 4 map directly to ISO 27018:2019 controls, representing 2% coverage. The remaining 160 controls represent compliance gaps requiring additional documentation or compensating controls to satisfy both frameworks simultaneously.
What are the compliance gaps when mapping ISO/SAE 21434 to ISO 27018:2019?
160 ISO/SAE 21434 controls have no direct equivalent in ISO 27018:2019. The highest concentration of gaps is in Superseded batch representation – ISO/SAE 21434 with 46 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/SAE 21434 and ISO 27018:2019?
The domain with the highest gap count is Superseded batch representation – ISO/SAE 21434 (46 gaps). Export the full domain-by-domain gap breakdown via the Professional tier to generate a prioritised remediation roadmap.
