ISO 27001:2022 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 ISO 27001:2022. 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 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.
64 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.
Information security awareness, education and training covers operational teams by role.
Authentication information management covers password choice and length rules.
Authentication information must be protected, which covers stored password form.
Secure authentication is where strong authentication for privileged and external access sits.
Configuration management with secure baselines is the minimum estate security level.
Storage media handling covers use, transfer and inspection of removable media.
Network security includes host level filtering of unnecessary inbound connections.
Use of cryptography covers encrypting sensitive data sent over the internet.
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.
The full report
Everything above is a sample. The report is every evidenced control and every gap, with the reasoning and the source document behind each one, in a form you can hand to an assessor. $299, emailed immediately.
