Coverage crosswalk

The NIST SP 800-171 Rev 3 to ISO 27001:2022 crosswalk

The table above lists candidate mappings. A crosswalk answers the narrower question you are probably here for: which ISO 27001:2022 controls your existing NIST SP 800-171 Rev 3 work already satisfies, which are real gaps, and the reasoning behind every claim so you can check it. One pair, $299, one time.

58.1%

54 of 93 ISO 27001:2022 controls are evidenced by work you have already done for NIST SP 800-171 Rev 3. 39 are genuine gaps.

Every claim shows its reasoning so you can check it. Ask and a practitioner will review this pair.

A sample of what the report says

Evidenced: 5.1 Policies for information security

Requires documented, disseminated and periodically reviewed security policy and procedures per control family.

Grounded in 03.15.01 Policy and Procedures. Confidence high, survived the refutation pass.

Gap: 5.12 Classification of information

Classify information by confidentiality, integrity, availability and interested-party requirements.

Every one of the 54 evidenced controls and 39 gaps in the report carries this much reasoning, so you can check the claim rather than take it on trust.

Why this page shows two different percentages. The 99% in the header counts how many NIST SP 800-171 Rev 3 controls carry at least one candidate mapping in the graph, before any review. The crosswalk percentage counts something stricter: how many ISO 27001:2022 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 800-171 Rev 3 and ISO 27001:2022?

NIST SP 800-171 Rev 3 has 97 controls across its framework, while ISO 27001:2022 covers 93 controls. Direct mapping analysis identifies 96 overlapping controls (99% coverage). The frameworks diverge most significantly in 03.13 SC (System and Communications Protection), where 1 NIST SP 800-171 Rev 3 controls have no direct ISO 27001:2022 equivalent.

How many controls map between NIST SP 800-171 Rev 3 and ISO 27001:2022?

Of 97 total NIST SP 800-171 Rev 3 controls, 96 map directly to ISO 27001:2022 controls, representing 99% coverage. The remaining 1 controls represent compliance gaps requiring additional documentation or compensating controls to satisfy both frameworks simultaneously.

What are the compliance gaps when mapping NIST SP 800-171 Rev 3 to ISO 27001:2022?

1 NIST SP 800-171 Rev 3 controls have no direct equivalent in ISO 27001:2022. The highest concentration of gaps is in 03.13 SC (System and Communications Protection) with 1 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 800-171 Rev 3 and ISO 27001:2022?

The domain with the highest gap count is 03.13 SC (System and Communications Protection) (1 gaps). Export the full domain-by-domain gap breakdown via the Professional tier to generate a prioritised remediation roadmap.
