The ISO 27701:2019 to NIST SP 800-171 Rev 3 crosswalk
The table above lists candidate mappings. A crosswalk answers the narrower question you are probably here for: which NIST SP 800-171 Rev 3 controls your existing ISO 27701:2019 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.
32 of 108 ISO 27701:2019 controls are evidenced by work you have already done for NIST SP 800-171 Rev 3. 76 are genuine gaps.
- 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 42% in the header counts how many ISO 27701:2019 controls carry at least one candidate mapping in the graph, before any review. The crosswalk percentage counts something stricter: how many NIST SP 800-171 Rev 3 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 27701:2019 and NIST SP 800-171 Rev 3?
ISO 27701:2019 has 108 controls across its framework, while NIST SP 800-171 Rev 3 covers 97 controls. Direct mapping analysis identifies 45 overlapping controls (42% coverage). The frameworks diverge most significantly in Additional ISO/IEC 27002 guidance for PII controllers, ISO 27701:2019, where 28 ISO 27701:2019 controls have no direct NIST SP 800-171 Rev 3 equivalent.
How many controls map between ISO 27701:2019 and NIST SP 800-171 Rev 3?
Of 108 total ISO 27701:2019 controls, 45 map directly to NIST SP 800-171 Rev 3 controls, representing 42% coverage. The remaining 63 controls represent compliance gaps requiring additional documentation or compensating controls to satisfy both frameworks simultaneously.
What are the compliance gaps when mapping ISO 27701:2019 to NIST SP 800-171 Rev 3?
63 ISO 27701:2019 controls have no direct equivalent in NIST SP 800-171 Rev 3. The highest concentration of gaps is in Additional ISO/IEC 27002 guidance for PII controllers, ISO 27701:2019 with 28 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 27701:2019 and NIST SP 800-171 Rev 3?
The domain with the highest gap count is Additional ISO/IEC 27002 guidance for PII controllers, ISO 27701:2019 (28 gaps). Export the full domain-by-domain gap breakdown via the Professional tier to generate a prioritised remediation roadmap.
