NIST SP 800-53 Rev 5 covers 47.5% of PCI DSS 4.0
133 of the 280 controls in PCI DSS 4.0 are already satisfied by evidence you collected for NIST SP 800-53 Rev 5. 147 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
PCI DSS 4.0 has 280 controls. Holding NIST SP 800-53 Rev 5 already evidences 133 of them, so the work in front of you is 147 controls, not 280, which is 53% 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 133 controls of PCI DSS 4.0 you do not have to implement again, which is $2.25 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 133 already evidenced are | 532 hours | 1,064 hours | 2,128 hours |
| and the 147 remaining are | 588 hours | 1,176 hours | 2,352 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 PCI DSS 4.0 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.
705 candidate mappings were examined and 449 were removed. Signed off 2026-08-19.
Claims that did not hold
449 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.
