A OpenSSF Scorecard 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 OpenSSF Scorecard work already satisfies, which are real gaps, and the reasoning behind every claim so you can check it. One pair, $299, one time.

OpenSSF Scorecard into ISO/SAE 21434
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.

Why this page shows two different percentages. The 88% in the header counts how many OpenSSF Scorecard 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.
