UK Cyber Essentials covers 28.6% of ANSSI Guide d'hygiene informatique (42 mesures, v2.0)
12 of the 42 controls in ANSSI Guide d'hygiene informatique (42 mesures, v2.0) are already satisfied by evidence you collected for UK Cyber Essentials. 30 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 UK Cyber Essentials 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.
42 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.
Both set password length and quality rules and require they be enforced.
Both require vendor default passwords changed or removed before deployment.
Both require default administrative credentials on network equipment to be changed.
Recognised passwordless methods such as FIDO2 are the strong authentication ANSSI asks for.
Both mandate strong authentication for privileged administrative accounts.
Both require multi-factor authentication for externally reachable cloud service accounts.
Both require unnecessary accounts, software and services removed to set a baseline.
Both require the host-based software firewall enabled and configured on workstations.
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.
