CMMC 2.0vsNIST SP 800-53 Rev 5
See exactly how CMMC 2.0 controls map to NIST SP 800-53 Rev 5. Pre-computed mappings, identified gaps, and coverage analysis.
A reviewed coverage crosswalk for this pair is available. See which NIST SP 800-53 Rev 5 controls you already evidence.
According to the TheArtOfService Compliance Knowledge Graph:
CMMC 2.0 maps to NIST SP 800-53 Rev 5 with 100% coverage across 110 directly mapped controls. Analysis of 110 CMMC 2.0 controls identifies 0 compliance gaps, primarily concentrated in System and Information Integrity.

The CMMC 2.0 to NIST SP 800-53 Rev 5 crosswalk
The table above lists candidate mappings. A crosswalk answers the narrower question you are probably here for: which NIST SP 800-53 Rev 5 controls your existing CMMC 2.0 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. CMMC 2.0 into NIST SP 800-53 Rev 5 lands at 28.7%, while NIST SP 800-53 Rev 5 into CMMC 2.0 lands at 85.5%, 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 CMMC 2.0 evidence buys you for NIST SP 800-53 Rev 5, the other asks the reverse.
86 of 300 NIST SP 800-53 Rev 5 controls are evidenced by work you have already done for CMMC 2.0. 214 are genuine gaps.
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.
A sample of what the report says
AC-2 governs which users and devices hold accounts and therefore system access.
Grounded in NIST800-AC-2 Account management. Confidence high, survived the refutation pass.
Monitor and control remote access sessions so each remote connection is authorized, visible to the organization and subject to enforcement.
Every one of the 94 evidenced controls and 16 gaps in the report carries this much reasoning, so you can check the claim rather than take it on trust.
- 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 100% in the header counts how many CMMC 2.0 controls carry at least one candidate mapping in the graph, before any review. The crosswalk percentage counts something stricter: how many NIST SP 800-53 Rev 5 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 CMMC 2.0 and NIST SP 800-53 Rev 5?
CMMC 2.0 has 110 controls across its framework, while NIST SP 800-53 Rev 5 covers 300 controls. Direct mapping analysis identifies 110 overlapping controls (100% coverage). The frameworks diverge most significantly in System and Information Integrity, where 0 CMMC 2.0 controls have no direct NIST SP 800-53 Rev 5 equivalent.
How many controls map between CMMC 2.0 and NIST SP 800-53 Rev 5?
Of 110 total CMMC 2.0 controls, 110 map directly to NIST SP 800-53 Rev 5 controls, representing 100% coverage. The remaining 0 controls represent compliance gaps requiring additional documentation or compensating controls to satisfy both frameworks simultaneously.
What are the compliance gaps when mapping CMMC 2.0 to NIST SP 800-53 Rev 5?
0 CMMC 2.0 controls have no direct equivalent in NIST SP 800-53 Rev 5. The highest concentration of gaps is in System and Information Integrity with 0 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 CMMC 2.0 and NIST SP 800-53 Rev 5?
The domain with the highest gap count is System and Information Integrity (0 gaps). Export the full domain-by-domain gap breakdown via the Professional tier to generate a prioritised remediation roadmap.
