ISO/SAE 21434vsNIST SP 800-137
See exactly how ISO/SAE 21434 controls map to NIST SP 800-137. 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:
ISO/SAE 21434 maps to NIST SP 800-137 with 10% coverage across 17 directly mapped controls. Analysis of 164 ISO/SAE 21434 controls identifies 147 compliance gaps, primarily concentrated in Superseded batch representation – ISO/SAE 21434.

A ISO/SAE 21434 to NIST SP 800-137 crosswalk, built to order
The table above lists candidate mappings. A crosswalk answers the narrower question you are probably here for: which NIST SP 800-137 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.
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 10% 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 NIST SP 800-137 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 NIST SP 800-137?
ISO/SAE 21434 has 164 controls across its framework, while NIST SP 800-137 covers 8 controls. Direct mapping analysis identifies 17 overlapping controls (10% coverage). The frameworks diverge most significantly in Superseded batch representation – ISO/SAE 21434, where 33 ISO/SAE 21434 controls have no direct NIST SP 800-137 equivalent.
How many controls map between ISO/SAE 21434 and NIST SP 800-137?
Of 164 total ISO/SAE 21434 controls, 17 map directly to NIST SP 800-137 controls, representing 10% coverage. The remaining 147 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 NIST SP 800-137?
147 ISO/SAE 21434 controls have no direct equivalent in NIST SP 800-137. The highest concentration of gaps is in Superseded batch representation – ISO/SAE 21434 with 33 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 NIST SP 800-137?
The domain with the highest gap count is Superseded batch representation – ISO/SAE 21434 (33 gaps). Export the full domain-by-domain gap breakdown via the Professional tier to generate a prioritised remediation roadmap.
