A ISO/IEC 27043:2015 to SLSA crosswalk, built to order
The table above lists candidate mappings. A crosswalk answers the narrower question you are probably here for: which SLSA controls your existing ISO/IEC 27043:2015 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 20% in the header counts how many ISO/IEC 27043:2015 controls carry at least one candidate mapping in the graph, before any review. The crosswalk percentage counts something stricter: how many SLSA 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/IEC 27043:2015 and SLSA?
ISO/IEC 27043:2015 has 89 controls across its framework, while SLSA covers 68 controls. Direct mapping analysis identifies 18 overlapping controls (20% coverage). The frameworks diverge most significantly in Superseded batch representation – ISO/IEC 27043:2015, where 34 ISO/IEC 27043:2015 controls have no direct SLSA equivalent.
How many controls map between ISO/IEC 27043:2015 and SLSA?
Of 89 total ISO/IEC 27043:2015 controls, 18 map directly to SLSA controls, representing 20% coverage. The remaining 82 controls represent compliance gaps requiring additional documentation or compensating controls to satisfy both frameworks simultaneously.
What are the compliance gaps when mapping ISO/IEC 27043:2015 to SLSA?
82 ISO/IEC 27043:2015 controls have no direct equivalent in SLSA. The highest concentration of gaps is in Superseded batch representation – ISO/IEC 27043:2015 with 34 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/IEC 27043:2015 and SLSA?
The domain with the highest gap count is Superseded batch representation – ISO/IEC 27043:2015 (34 gaps). Export the full domain-by-domain gap breakdown via the Professional tier to generate a prioritised remediation roadmap.
