The NIST SP 800-53 Rev 5 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 800-53 Rev 5 work already satisfies, which are real gaps, and the reasoning behind every claim so you can check it. One pair, $299, one time.
Coverage does not run both ways. NIST SP 800-53 Rev 5 into ISO 27001:2022 lands at 84.9%, while ISO 27001:2022 into NIST SP 800-53 Rev 5 lands at 54.3%, on the same two control sets. That is not a rounding difference. It is the whole reason these are two separate reports: one asks what your NIST SP 800-53 Rev 5 evidence buys you for ISO 27001:2022, the other asks the reverse.
79 of 93 ISO 27001:2022 controls are evidenced by work you have already done for NIST SP 800-53 Rev 5. 14 are genuine gaps.
A sample of what the report says
Organization-wide security program plan approved, disseminated and reviewed evidences the policy set.
Grounded in NIST800-PM-1 Information Security Program Plan. Develop and disseminate an organization-wide information security program plan that: Provides an overview of the requirements for the security program and a description of the security program management controls and. Confidence high, survived the refutation pass.
Label information consistently with the classification scheme so handling rules can follow it.
Every one of the 79 evidenced controls and 14 gaps in the report carries this much reasoning, so you can check the claim rather than take it on trust.
163 of 300 NIST SP 800-53 Rev 5 controls are evidenced by work you have already done for ISO 27001:2022. 137 are genuine gaps.
A sample of what the report says
Policies for information security include the access control policy required.
Grounded in iso-27001-2022::5.1 Policies for information security. Confidence high, survived the refutation pass.
Concurrent Session Control. Limit the number of concurrent sessions for each [organization-defined] to [organization-defined]
Every one of the 163 evidenced controls and 137 gaps in the report carries this much reasoning, so you can check the claim rather than take it on trust.
- 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 84% in the header counts how many NIST SP 800-53 Rev 5 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 800-53 Rev 5 and ISO 27001:2022?
NIST SP 800-53 Rev 5 has 300 controls across its framework, while ISO 27001:2022 covers 93 controls. Direct mapping analysis identifies 269 overlapping controls (84% coverage). The frameworks diverge most significantly in SC - System and Communications Protection, where 19 NIST SP 800-53 Rev 5 controls have no direct ISO 27001:2022 equivalent.
How many controls map between NIST SP 800-53 Rev 5 and ISO 27001:2022?
Of 300 total NIST SP 800-53 Rev 5 controls, 269 map directly to ISO 27001:2022 controls, representing 84% coverage. The remaining 51 controls represent compliance gaps requiring additional documentation or compensating controls to satisfy both frameworks simultaneously.
What are the compliance gaps when mapping NIST SP 800-53 Rev 5 to ISO 27001:2022?
51 NIST SP 800-53 Rev 5 controls have no direct equivalent in ISO 27001:2022. The highest concentration of gaps is in SC - System and Communications Protection with 19 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 800-53 Rev 5 and ISO 27001:2022?
The domain with the highest gap count is SC - System and Communications Protection (19 gaps). Export the full domain-by-domain gap breakdown via the Professional tier to generate a prioritised remediation roadmap.
