SLSAvsISO/SAE 21434
See exactly how SLSA controls map to ISO/SAE 21434. 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:
SLSA maps to ISO/SAE 21434 with 4% coverage across 3 directly mapped controls. Analysis of 68 SLSA controls identifies 65 compliance gaps, primarily concentrated in Superseded batch representation – SLSA.

A SLSA to ISO/SAE 21434 crosswalk, built to order
The table above lists candidate mappings. A crosswalk answers the narrower question you are probably here for: which ISO/SAE 21434 controls your existing SLSA 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 gap, with what it requires
- Its level of review stated plainly, not a bare number
Why this page shows two different percentages. The 4% in the header counts how many SLSA controls carry at least one candidate mapping in the graph, before any review. The crosswalk percentage counts something stricter: how many ISO/SAE 21434 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 SLSA and ISO/SAE 21434?
SLSA has 68 controls across its framework, while ISO/SAE 21434 covers 164 controls. Direct mapping analysis identifies 3 overlapping controls (4% coverage). The frameworks diverge most significantly in Superseded batch representation – SLSA, where 21 SLSA controls have no direct ISO/SAE 21434 equivalent.
How many controls map between SLSA and ISO/SAE 21434?
Of 68 total SLSA controls, 3 map directly to ISO/SAE 21434 controls, representing 4% coverage. The remaining 65 controls represent compliance gaps requiring additional documentation or compensating controls to satisfy both frameworks simultaneously.
What are the compliance gaps when mapping SLSA to ISO/SAE 21434?
65 SLSA controls have no direct equivalent in ISO/SAE 21434. The highest concentration of gaps is in Superseded batch representation – SLSA with 21 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 SLSA and ISO/SAE 21434?
The domain with the highest gap count is Superseded batch representation – SLSA (21 gaps). Export the full domain-by-domain gap breakdown via the Professional tier to generate a prioritised remediation roadmap.
