A IEC 62443 to ISO 27019 crosswalk, built to order
The table above lists candidate mappings. A crosswalk answers the narrower question you are probably here for: which ISO 27019 controls your existing IEC 62443 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 21% in the header counts how many IEC 62443 controls carry at least one candidate mapping in the graph, before any review. The crosswalk percentage counts something stricter: how many ISO 27019 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 IEC 62443 and ISO 27019?
IEC 62443 has 81 controls across its framework, while ISO 27019 covers 46 controls. Direct mapping analysis identifies 17 overlapping controls (21% coverage). The frameworks diverge most significantly in 62443-3-3 System Security Requirements, where 24 IEC 62443 controls have no direct ISO 27019 equivalent.
How many controls map between IEC 62443 and ISO 27019?
Of 81 total IEC 62443 controls, 17 map directly to ISO 27019 controls, representing 21% coverage. The remaining 64 controls represent compliance gaps requiring additional documentation or compensating controls to satisfy both frameworks simultaneously.
What are the compliance gaps when mapping IEC 62443 to ISO 27019?
64 IEC 62443 controls have no direct equivalent in ISO 27019. The highest concentration of gaps is in 62443-3-3 System Security Requirements with 24 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 IEC 62443 and ISO 27019?
The domain with the highest gap count is 62443-3-3 System Security Requirements (24 gaps). Export the full domain-by-domain gap breakdown via the Professional tier to generate a prioritised remediation roadmap.
