A NIST SP 800-171A Rev 3 - Assessing CUI Security Requirements to ISO 27005 crosswalk, built to order
The table above lists candidate mappings. A crosswalk answers the narrower question you are probably here for: which ISO 27005 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 26% 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 ISO 27005 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 NIST SP 800-171A Rev 3 - Assessing CUI Security Requirements and ISO 27005?
NIST SP 800-171A Rev 3 - Assessing CUI Security Requirements has 35 controls across its framework, while ISO 27005 covers 26 controls. Direct mapping analysis identifies 9 overlapping controls (26% coverage). The frameworks diverge most significantly in System Protection and Communications, where 12 NIST SP 800-171A Rev 3 - Assessing CUI Security Requirements controls have no direct ISO 27005 equivalent.
How many controls map between NIST SP 800-171A Rev 3 - Assessing CUI Security Requirements and ISO 27005?
Of 35 total NIST SP 800-171A Rev 3 - Assessing CUI Security Requirements controls, 9 map directly to ISO 27005 controls, representing 26% coverage. The remaining 26 controls represent compliance gaps requiring additional documentation or compensating controls to satisfy both frameworks simultaneously.
What are the compliance gaps when mapping NIST SP 800-171A Rev 3 - Assessing CUI Security Requirements to ISO 27005?
26 NIST SP 800-171A Rev 3 - Assessing CUI Security Requirements controls have no direct equivalent in ISO 27005. The highest concentration of gaps is in System Protection and Communications with 12 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 NIST SP 800-171A Rev 3 - Assessing CUI Security Requirements and ISO 27005?
