NIST SP 800-53 Rev 5 covers 68.6% of NIST SP 800-172
24 of the 35 controls in NIST SP 800-172 are already satisfied by evidence you collected for NIST SP 800-53 Rev 5. 11 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 800-172 has 35 controls. Holding NIST SP 800-53 Rev 5 already evidences 24 of them, so the work in front of you is 11 controls, not 35, which is 31% 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 24 controls of NIST SP 800-172 you do not have to implement again, which is $12.46 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 24 already evidenced are | 96 hours | 192 hours | 384 hours |
| and the 11 remaining are | 44 hours | 88 hours | 176 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 800-172 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.
48 candidate mappings were examined and 5 were removed. Signed off 2026-08-19.
Claims that did not hold
5 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.
