See exactly how NIST SP 800-53A Rev. 5 controls map to FedRAMP High. Pre-computed mappings, identified gaps, and coverage analysis.
Need this as a report you can hand to an assessor? A coverage crosswalk for this pair can be built to order.
According to the TheArtOfService Compliance Knowledge Graph:
NIST SP 800-53A Rev. 5 maps to FedRAMP High with 47% coverage across 14 directly mapped controls. Analysis of 30 NIST SP 800-53A Rev. 5 controls identifies 16 compliance gaps, primarily concentrated in Chapter Three: The Assessment Process.

A NIST SP 800-53A Rev. 5 to FedRAMP High crosswalk, built to order
The table above lists candidate mappings. A crosswalk answers the narrower question you are probably here for: which FedRAMP High controls your existing NIST SP 800-53A 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.
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 800-53A Rev. 5 controls carry at least one candidate mapping in the graph, before any review. The crosswalk percentage counts something stricter: how many FedRAMP High 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 800-53A Rev. 5 and FedRAMP High?
NIST SP 800-53A Rev. 5 has 30 controls across its framework, while FedRAMP High covers 410 controls. Direct mapping analysis identifies 14 overlapping controls (47% coverage). The frameworks diverge most significantly in Chapter Three: The Assessment Process, where 9 NIST SP 800-53A Rev. 5 controls have no direct FedRAMP High equivalent.
How many controls map between NIST SP 800-53A Rev. 5 and FedRAMP High?
Of 30 total NIST SP 800-53A Rev. 5 controls, 14 map directly to FedRAMP High controls, representing 47% coverage. The remaining 16 controls represent compliance gaps requiring additional documentation or compensating controls to satisfy both frameworks simultaneously.
What are the compliance gaps when mapping NIST SP 800-53A Rev. 5 to FedRAMP High?
16 NIST SP 800-53A Rev. 5 controls have no direct equivalent in FedRAMP High. The highest concentration of gaps is in Chapter Three: The Assessment Process with 9 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 800-53A Rev. 5 and FedRAMP High?
The domain with the highest gap count is Chapter Three: The Assessment Process (9 gaps). Export the full domain-by-domain gap breakdown via the Professional tier to generate a prioritised remediation roadmap.
