CMMC 2.0 covers 31.5% of ISO 27701:2019
34 of the 108 controls in ISO 27701:2019 are already satisfied by evidence you collected for CMMC 2.0. 74 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 ISO 27701:2019 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.
95 candidate mappings were examined and 15 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 held
A sample. Each one names the control whose evidence does the work, the control it satisfies, and why.
Both require the system boundary and operating environment to be determined and documented.
Both require risks assessed so that actions to address them can be chosen.
Both require personnel competent for the security duties assigned to them.
Both require personnel made aware of security risks and the policies governing them.
Both require periodic assessment of risk to systems and the information they hold.
Both require identified risks treated in the priority order the assessment sets.
Both require control effectiveness monitored on an ongoing basis.
Both require corrective action plans against identified deficiencies.
Claims that did not hold
15 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.
Generated by the retired metered path, which was refuted at 56 percent wherever it was re-judged. Held back so an unreleased pair cannot be signed off on unreviewed mappings. Re-judge on the Max plan to revive.
Claimed at high confidence before it was rejected.
retired metered-API path. 56 percent of its output was refuted wherever it was re-judged, so its residue is not trusted evidence. Superseded by judgement on the Claude Max plan 2026-08-19.
Claimed at medium confidence before it was rejected.
