ISO 27001:2022 covers 55.8% of PCI DSS 4.0
139 of the 249 controls in PCI DSS 4.0 are already satisfied by evidence you collected for ISO 27001:2022. 110 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 PCI DSS 4.0 your ISO 27001:2022 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.
579 candidate mappings were examined and 415 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.
Policies for information security include the network security control policy.
Information security roles and responsibilities assigns ownership for network controls.
Configuration management defines network security control standards.
Change management reviews and approves changes to network controls.
Configuration management enumerates and justifies enabled services and ports.
Security of network services defines protections for insecure services.
Networks security requires rule sets be reviewed and kept current.
Configuration management protects and synchronises device configuration files.
Claims that did not hold
406 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.
Held back 2026-08-19. Generated by the retired metered path, refuted at 56 percent wherever re-judged. Pair pulled from sale pending a rebuild on the Max plan.
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.
