SOC 2vsISO/IEC 27018:2019
See exactly how SOC 2 controls map to ISO/IEC 27018:2019. Pre-computed mappings, identified gaps, and coverage analysis.
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:
SOC 2 maps to ISO/IEC 27018:2019 with 11% coverage across 7 directly mapped controls. Analysis of 61 SOC 2 controls identifies 54 compliance gaps, primarily concentrated in CC - Common Criteria (Security).

A SOC 2 to ISO/IEC 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/IEC 27018:2019 controls your existing SOC 2 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 11% in the header counts how many SOC 2 controls carry at least one candidate mapping in the graph, before any review. The crosswalk percentage counts something stricter: how many ISO/IEC 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 SOC 2 and ISO/IEC 27018:2019?
SOC 2 has 61 controls across its framework, while ISO/IEC 27018:2019 covers 30 controls. Direct mapping analysis identifies 7 overlapping controls (11% coverage). The frameworks diverge most significantly in CC - Common Criteria (Security), where 30 SOC 2 controls have no direct ISO/IEC 27018:2019 equivalent.
How many controls map between SOC 2 and ISO/IEC 27018:2019?
Of 61 total SOC 2 controls, 7 map directly to ISO/IEC 27018:2019 controls, representing 11% coverage. The remaining 54 controls represent compliance gaps requiring additional documentation or compensating controls to satisfy both frameworks simultaneously.
What are the compliance gaps when mapping SOC 2 to ISO/IEC 27018:2019?
54 SOC 2 controls have no direct equivalent in ISO/IEC 27018:2019. The highest concentration of gaps is in CC - Common Criteria (Security) with 30 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 SOC 2 and ISO/IEC 27018:2019?
The domain with the highest gap count is CC - Common Criteria (Security) (30 gaps). Export the full domain-by-domain gap breakdown via the Professional tier to generate a prioritised remediation roadmap.
