CIS Controls v8 covers 25% of ISO 27701:2019
27 of the 108 controls in ISO 27701:2019 are already satisfied by evidence you collected for CIS Controls v8. 81 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 CIS Controls v8 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.
200 candidate mappings were examined and 84 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.
Secure network architecture addressing segmentation is the network control limb.
Traffic filtering between segments is segregation in networks.
A maintained secure network architecture is network security management.
Filtering between segments delivers segregation in networks.
Encrypting sensitive data in transit is the technical core of information transfer.
A secure application development process with design standards is this clause.
Applying secure design principles in architectures is security and privacy by design.
Secure application design standards are the security requirements specification.
Claims that did not hold
84 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.
