PCI DSS 4.0vsCMMC 2.0
See exactly how PCI DSS 4.0 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:
PCI DSS 4.0 maps to CMMC 2.0 with 80% coverage across 199 directly mapped controls. Analysis of 249 PCI DSS 4.0 controls identifies 50 compliance gaps, primarily concentrated in Req 3: Protect Stored Account Data.

The PCI DSS 4.0 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 PCI DSS 4.0 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. PCI DSS 4.0 into CMMC 2.0 lands at 61.8%, while CMMC 2.0 into PCI DSS 4.0 lands at 37.3%, 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 PCI DSS 4.0 evidence buys you for CMMC 2.0, the other asks the reverse.
68 of 110 CMMC 2.0 controls are evidenced by work you have already done for PCI DSS 4.0. 42 are genuine gaps.
A sample of what the report says
PCI assigns a unique ID to every user before any system access is allowed
Grounded in 8.2.1 All users are assigned a unique ID before access to system components or cardholder data is allowed. Confidence high, survived the refutation pass.
Automatically end a user session once a defined condition, such as an inactivity period or maximum session duration, is met.
Every one of the 68 evidenced controls and 42 gaps in the report carries this much reasoning, so you can check the claim rather than take it on trust.
93 of 249 PCI DSS 4.0 controls are evidenced by work you have already done for CMMC 2.0. 156 are genuine gaps.
A sample of what the report says
Establishing and enforcing security configuration settings is the configuration standard for network controls.
Grounded in CM.L2-3.4.2 Security Configuration Enforcement. Confidence high, survived the refutation pass.
All security policies and operational procedures for Requirement 1 are documented, kept current, in use, and known to affected parties.
Every one of the 93 evidenced controls and 156 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 80% in the header counts how many PCI DSS 4.0 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 PCI DSS 4.0 and CMMC 2.0?
PCI DSS 4.0 has 249 controls across its framework, while CMMC 2.0 covers 110 controls. Direct mapping analysis identifies 199 overlapping controls (80% coverage). The frameworks diverge most significantly in Req 3: Protect Stored Account Data, where 14 PCI DSS 4.0 controls have no direct CMMC 2.0 equivalent.
How many controls map between PCI DSS 4.0 and CMMC 2.0?
Of 249 total PCI DSS 4.0 controls, 199 map directly to CMMC 2.0 controls, representing 80% coverage. The remaining 50 controls represent compliance gaps requiring additional documentation or compensating controls to satisfy both frameworks simultaneously.
What are the compliance gaps when mapping PCI DSS 4.0 to CMMC 2.0?
50 PCI DSS 4.0 controls have no direct equivalent in CMMC 2.0. The highest concentration of gaps is in Req 3: Protect Stored Account Data with 14 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 PCI DSS 4.0 and CMMC 2.0?
The domain with the highest gap count is Req 3: Protect Stored Account Data (14 gaps). Export the full domain-by-domain gap breakdown via the Professional tier to generate a prioritised remediation roadmap.
