ACSC Essential Eight covers 19% of CIS Controls v8
29 of the 153 controls in CIS Controls v8 are already satisfied by evidence you collected for ACSC Essential Eight. 124 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 CIS Controls v8 your ACSC Essential Eight 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.
51 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.
ASD hardening guidance for browsers and Office mandates the anti exploitation settings CIS lists.
Backups performed and retained against business criticality and continuity requirements, with restoration scope defined.
Backups of data, applications and settings are performed and synchronised to a common point.
Restoration from backups is tested as part of disaster recovery exercises.
Network device operating systems patched within defined windows and only current or previous releases used.
Secure Admin Workstations and jump servers are dedicated computing resources for administrative work.
Applications no longer supported by vendors are removed, which is the supported software requirement.
Blocklist plus allowlist on servers and workstations prevents unauthorised software running, with annual ruleset validation.
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.
