A NIST SP 800-53 Rev 5 LOW to NIST SP 800-66 Rev 2 crosswalk, built to order
The table above lists candidate mappings. A crosswalk answers the narrower question you are probably here for: which NIST SP 800-66 Rev 2 controls your existing NIST SP 800-53 Rev 5 LOW 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 47% in the header counts how many NIST SP 800-53 Rev 5 LOW controls carry at least one candidate mapping in the graph, before any review. The crosswalk percentage counts something stricter: how many NIST SP 800-66 Rev 2 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 LOW and NIST SP 800-66 Rev 2?
NIST SP 800-53 Rev 5 LOW has 173 controls across its framework, while NIST SP 800-66 Rev 2 covers 65 controls. Direct mapping analysis identifies 81 overlapping controls (47% coverage). The frameworks diverge most significantly in PM Program Management, where 32 NIST SP 800-53 Rev 5 LOW controls have no direct NIST SP 800-66 Rev 2 equivalent.
How many controls map between NIST SP 800-53 Rev 5 LOW and NIST SP 800-66 Rev 2?
Of 173 total NIST SP 800-53 Rev 5 LOW controls, 81 map directly to NIST SP 800-66 Rev 2 controls, representing 47% coverage. The remaining 92 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 LOW to NIST SP 800-66 Rev 2?
92 NIST SP 800-53 Rev 5 LOW controls have no direct equivalent in NIST SP 800-66 Rev 2. The highest concentration of gaps is in PM Program Management with 32 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 LOW and NIST SP 800-66 Rev 2?
The domain with the highest gap count is PM Program Management (32 gaps). Export the full domain-by-domain gap breakdown via the Professional tier to generate a prioritised remediation roadmap.
