NIST SP 800-53 Rev 5vsISO 27001:2022
See exactly how NIST SP 800-53 Rev 5 controls map to ISO 27001:2022. Pre-computed mappings, identified gaps, and coverage analysis.
A reviewed coverage crosswalk for this pair is available. See which ISO 27001:2022 controls you already evidence.
According to the TheArtOfService Compliance Knowledge Graph:
NIST SP 800-53 Rev 5 maps to ISO 27001:2022 with 25% coverage across 269 directly mapped controls. Analysis of 1,014 NIST SP 800-53 Rev 5 controls identifies 768 compliance gaps, primarily concentrated in AC - Access Control.

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 16.1%, 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.
163 of 1014 NIST SP 800-53 Rev 5 controls are evidenced by work you have already done for ISO 27001:2022. 851 are genuine gaps.

Why this page shows two different percentages. The 25% 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 1,014 controls across its framework, while ISO 27001:2022 covers 93 controls. Direct mapping analysis identifies 269 overlapping controls (25% coverage). The frameworks diverge most significantly in AC - Access Control, where 111 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 1,014 total NIST SP 800-53 Rev 5 controls, 269 map directly to ISO 27001:2022 controls, representing 25% coverage. The remaining 768 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?
768 NIST SP 800-53 Rev 5 controls have no direct equivalent in ISO 27001:2022. The highest concentration of gaps is in AC - Access Control with 111 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 AC - Access Control (111 gaps). Export the full domain-by-domain gap breakdown via the Professional tier to generate a prioritised remediation roadmap.
