PCI DSS 4.0 covers 76.2% of ANSSI Guide d'hygiene informatique (42 mesures, v2.0)
32 of the 42 controls in ANSSI Guide d'hygiene informatique (42 mesures, v2.0) are already satisfied by evidence you collected for PCI DSS 4.0. 10 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 ANSSI Guide d'hygiene informatique (42 mesures, v2.0) your PCI DSS 4.0 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.
117 candidate mappings were examined and 0 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.
Annual training of software development personnel covers the developer limb directly.
Minimum password length and complexity requirements are the selection and sizing rules.
Rendering all authentication factors unreadable with strong cryptography is this measure.
Managing vendor default accounts before use is exactly the measure.
Changing wireless vendor defaults before installation covers the wireless case.
MFA for all remote access from outside the network is the external access limb.
MFA for all non console access strengthens authentication broadly within the CDE.
MFA for administrative access into the environment is the privileged access limb.
Claims that did not hold
Nothing proposed for this pair was rejected in review. That is unusual and worth knowing rather than hiding: it means the candidate set was small and every candidate held.
