CIS Controls v8 covers 34% of NIST SP 800-53 Rev 5
102 of the 300 controls in NIST SP 800-53 Rev 5 are already satisfied by evidence you collected for CIS Controls v8. 198 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 CIS Controls v8 already evidences 102 of them, so the work in front of you is 198 controls, not 300, which is 66% 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 102 controls of NIST SP 800-53 Rev 5 you do not have to implement again, which is $2.93 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 102 already evidenced are | 408 hours | 816 hours | 1,632 hours |
| and the 198 remaining are | 792 hours | 1,584 hours | 3,168 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 CIS Controls v8 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.
515 candidate mappings were examined and 306 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.
Automatic device lockout applies device lock to portable endpoints.
Automatic session locking is device lock as this control defines it.
Requiring VPN for remote devices controls and monitors remote access.
Managing access control for remote assets governs remote connections.
Multi-factor authentication for remote access authorises remote sessions.
Enforced remote wipe is a mobile device access control requirement.
Separating enterprise workspaces controls mobile device access to data.
Encrypting end user devices protects data on mobile devices.
Claims that did not hold
302 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.
Held back 2026-08-19. Generated by the retired metered path, refuted at 56 percent wherever re-judged. Pair pulled from sale pending a rebuild on the Max plan.
Claimed at high confidence before it was rejected.
retired metered-API path. 56 percent of its output was refuted wherever it was re-judged, so its residue is not trusted evidence. Superseded by judgement on the Claude Max plan 2026-08-19.
Claimed at medium confidence before it was rejected.
