CMMC 2.0HIPAA Security Rule

CMMC 2.0 covers 49.3% of HIPAA Security Rule

33 of the 67 controls in HIPAA Security Rule are already satisfied by evidence you collected for CMMC 2.0. 34 are genuine gaps. Every claim below was judged against both control sets and then argued against; the ones that did not survive are published further down with the reason each failed.

This number is directional. It says how much of HIPAA Security Rule your CMMC 2.0 evidence satisfies. The reverse pair is a different number, often very different, because a security standard has enormous depth for access control and almost none for lawful basis or data subject rights.

109 candidate mappings were examined and 39 were removed. Signed off 2026-08-19, review level machine verified. Mappings were judged by Claude Code rather than read line by line by a practitioner. Every claim shows its reasoning so you can check it. Ask and a practitioner will review this pair.

Where the gaps are

Coverage is never evenly spread. A source standard usually satisfies one part of a target almost completely and barely touches another, and which part is which is the thing worth knowing before you plan the work.

Theme level, not control level, deliberately. The per-control list of what is evidenced and what is a gap is the report itself, so publishing it here would be publishing the thing being sold.

Claims that did not hold

38 proposed mappings for this pair were rejected. They are kept in the graph rather than deleted, so what was thrown out is as inspectable as what survived. A crosswalk that never rejects anything is not being judged.
