Coverage crosswalk

A ISO/SAE 21434 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/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.

ISO/SAE 21434 into SLSA
Not published yet

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 34% 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 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/SAE 21434 and SLSA?

ISO/SAE 21434 has 50 controls across its framework, while SLSA covers 24 controls. Direct mapping analysis identifies 17 overlapping controls (34% coverage). The frameworks diverge most significantly in TARA, where 5 ISO/SAE 21434 controls have no direct SLSA equivalent.

How many controls map between ISO/SAE 21434 and SLSA?

Of 50 total ISO/SAE 21434 controls, 17 map directly to SLSA controls, representing 34% coverage. The remaining 33 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 SLSA?

33 ISO/SAE 21434 controls have no direct equivalent in SLSA. The highest concentration of gaps is in TARA with 5 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 SLSA?

The domain with the highest gap count is TARA (5 gaps). Export the full domain-by-domain gap breakdown via the Professional tier to generate a prioritised remediation roadmap.
