NIST SP 800-53 Rev 5vsCMMC 2.0
See exactly how NIST SP 800-53 Rev 5 controls map to CMMC 2.0. Pre-computed mappings, identified gaps, and coverage analysis.
A reviewed coverage crosswalk for this pair is available. See which CMMC 2.0 controls you already evidence.
According to the TheArtOfService Compliance Knowledge Graph:
NIST SP 800-53 Rev 5 maps to CMMC 2.0 with 14% coverage across 140 directly mapped controls. Analysis of 1,014 NIST SP 800-53 Rev 5 controls identifies 874 compliance gaps, primarily concentrated in SC - System and Communications Protection.

The NIST SP 800-53 Rev 5 to CMMC 2.0 crosswalk
The table above lists candidate mappings. A crosswalk answers the narrower question you are probably here for: which CMMC 2.0 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 CMMC 2.0 lands at 85.5%, while CMMC 2.0 into NIST SP 800-53 Rev 5 lands at 8.5%, 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 CMMC 2.0, the other asks the reverse.
94 of 110 CMMC 2.0 controls are evidenced by work you have already done for NIST SP 800-53 Rev 5. 16 are genuine gaps.
86 of 1014 NIST SP 800-53 Rev 5 controls are evidenced by work you have already done for CMMC 2.0. 928 are genuine gaps.

- Its level of review stated plainly, not a bare number
Why this page shows two different percentages. The 14% 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 CMMC 2.0 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 CMMC 2.0?
NIST SP 800-53 Rev 5 has 1,014 controls across its framework, while CMMC 2.0 covers 110 controls. Direct mapping analysis identifies 140 overlapping controls (14% coverage). The frameworks diverge most significantly in SC - System and Communications Protection, where 120 NIST SP 800-53 Rev 5 controls have no direct CMMC 2.0 equivalent.
How many controls map between NIST SP 800-53 Rev 5 and CMMC 2.0?
Of 1,014 total NIST SP 800-53 Rev 5 controls, 140 map directly to CMMC 2.0 controls, representing 14% coverage. The remaining 874 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 CMMC 2.0?
874 NIST SP 800-53 Rev 5 controls have no direct equivalent in CMMC 2.0. The highest concentration of gaps is in SC - System and Communications Protection with 120 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 CMMC 2.0?
The domain with the highest gap count is SC - System and Communications Protection (120 gaps). Export the full domain-by-domain gap breakdown via the Professional tier to generate a prioritised remediation roadmap.
