The FedRAMP Moderate to NIST SP 800-218 crosswalk
The table above lists candidate mappings. A crosswalk answers the narrower question you are probably here for: which NIST SP 800-218 controls your existing FedRAMP Moderate 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. FedRAMP Moderate into NIST SP 800-218 lands at 42.9%, while NIST SP 800-218 into FedRAMP Moderate lands at 6.8%, 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 FedRAMP Moderate evidence buys you for NIST SP 800-218, the other asks the reverse.
18 of 42 NIST SP 800-218 controls are evidenced by work you have already done for FedRAMP Moderate. 24 are genuine gaps.
22 of 323 FedRAMP Moderate controls are evidenced by work you have already done for NIST SP 800-218. 301 are genuine gaps.

Why this page shows two different percentages. The 15% in the header counts how many FedRAMP Moderate controls carry at least one candidate mapping in the graph, before any review. The crosswalk percentage counts something stricter: how many NIST SP 800-218 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 FedRAMP Moderate and NIST SP 800-218?
FedRAMP Moderate has 323 controls across its framework, while NIST SP 800-218 covers 42 controls. Direct mapping analysis identifies 50 overlapping controls (15% coverage). The frameworks diverge most significantly in AC - Access Control, where 43 FedRAMP Moderate controls have no direct NIST SP 800-218 equivalent.
How many controls map between FedRAMP Moderate and NIST SP 800-218?
Of 323 total FedRAMP Moderate controls, 50 map directly to NIST SP 800-218 controls, representing 15% coverage. The remaining 273 controls represent compliance gaps requiring additional documentation or compensating controls to satisfy both frameworks simultaneously.
What are the compliance gaps when mapping FedRAMP Moderate to NIST SP 800-218?
273 FedRAMP Moderate controls have no direct equivalent in NIST SP 800-218. The highest concentration of gaps is in AC - Access Control with 43 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 FedRAMP Moderate and NIST SP 800-218?
The domain with the highest gap count is AC - Access Control (43 gaps). Export the full domain-by-domain gap breakdown via the Professional tier to generate a prioritised remediation roadmap.
