ISO 27002:2022 covers 36.7% of NIST SP 800-53 Rev 5
110 of the 300 controls in NIST SP 800-53 Rev 5 are already satisfied by evidence you collected for ISO 27002:2022. 190 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.
What this leaves you to do
NIST SP 800-53 Rev 5 has 300 controls. Holding ISO 27002:2022 already evidences 110 of them, so the work in front of you is 190 controls, not 300, which is 63% of the standard rather than all of it.
That is the whole claim. Every number in that sentence comes from the two counts above it and can be re-derived from the free tools without taking our word for any of it.
In money, using only our numbers. The full report is $299 and names 110 controls of NIST SP 800-53 Rev 5 you do not have to implement again, which is $2.72 per control identified. That arithmetic uses our price and our count and assumes nothing about you.
In your hours, using your assumption. We do not know what a control costs you to implement, so pick the column that looks like your organisation. These are your figures, not our claim.
| If a control takes you | 4 hours | 8 hours | 16 hours |
|---|---|---|---|
| the 110 already evidenced are | 440 hours | 880 hours | 1,760 hours |
| and the 190 remaining are | 760 hours | 1,520 hours | 3,040 hours |
Multiply by your own rate. We publish no rate because we have not measured yours, and a number built on an invented rate is the kind of claim this platform exists to argue against.
This number is directional. It says how much of NIST SP 800-53 Rev 5 your ISO 27002:2022 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.
489 candidate mappings were examined and 253 were removed. Signed off 2026-08-19.
Claims that did not hold
253 proposed mappings for this pair were rejected. They are kept in the graph rather than deleted, so what was thrown out is as inspectable as what survived. A crosswalk that never rejects anything is not being judged.

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.
