NIST SP 800-53 Rev 5 covers 83.5% of Azure Security Benchmark
71 of the 85 controls in Azure Security Benchmark are already satisfied by evidence you collected for NIST SP 800-53 Rev 5. 14 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 Azure Security Benchmark your NIST SP 800-53 Rev 5 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.
148 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.
An accurate component inventory kept current at the needed granularity with owner attributes matches.
Prohibiting or restricting the software and services not essential to the mission is service approval.
Least privilege limits who may change the management plane, which is asset management access.
Prohibiting unauthorized software and restricting execution is application allow listing.
Backups of user and system level information at a defined frequency with protection matches.
Backups must have their confidentiality, integrity and availability protected.
Backup obligations require the backup process to run and be confirmed against the defined policy.
Contingency plan testing at a defined frequency establishes that recovery actually works.
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.
