NIST SP 800-171 Rev 3 covers 41.8% of CIS Controls v8
64 of the 153 controls in CIS Controls v8 are already satisfied by evidence you collected for NIST SP 800-171 Rev 3. 89 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
CIS Controls v8 has 153 controls. Holding NIST SP 800-171 Rev 3 already evidences 64 of them, so the work in front of you is 89 controls, not 153, which is 58% 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 64 controls of CIS Controls v8 you do not have to implement again, which is $4.67 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 64 already evidenced are | 256 hours | 512 hours | 1,024 hours |
| and the 89 remaining are | 356 hours | 712 hours | 1,424 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 CIS Controls v8 your NIST SP 800-171 Rev 3 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.
119 candidate mappings were examined and 0 were removed. Signed off 2026-08-19.
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.
