A NIST SP 800-171A Rev 3 - Assessing CUI Security Requirements to SSAE 18 - Attestation Standards (SOC Reporting) crosswalk, built to order
The table above lists candidate mappings. A crosswalk answers the narrower question you are probably here for: which SSAE 18 - Attestation Standards (SOC Reporting) controls your existing NIST SP 800-171A Rev 3 - Assessing CUI Security Requirements 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 31% in the header counts how many NIST SP 800-171A Rev 3 - Assessing CUI Security Requirements controls carry at least one candidate mapping in the graph, before any review. The crosswalk percentage counts something stricter: how many SSAE 18 - Attestation Standards (SOC Reporting) 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.
