Framework overlap

Does CISA Zero Trust Maturity Model cover NIST SP 800-172?

You hold CISA Zero Trust Maturity Model and have been told to do NIST SP 800-172. Here is how much overlaps, control by control.

47% of NIST SP 800-172 you already have

CISA Zero Trust Maturity Model already covers about 47% of NIST SP 800-172, leaving 19 of 36 controls as genuinely new work.

Already covered 0 Likely covered 17 New work 19

No control in CISA Zero Trust Maturity Model maps directly to one in NIST SP 800-172. Everything counted as covered is covered because both map to the same third standard, which is what a crosswalk is, but it is an inference rather than a lookup.

What is genuinely new work

Nothing in CISA Zero Trust Maturity Model reaches these. This is the list to scope.

How this is calculated

Already covered means a mapping runs from a control in CISA Zero Trust Maturity Model to that control. Likely covered means no direct mapping exists but both frameworks map to the same control in a third standard. New work means neither. We keep those separate rather than adding them into one friendlier number, because blending them would present a two-hop inference as a verified fact.

Coverage is not symmetric. Run it the other way and you will get a different number; both are correct.

From 332,959 cross-framework control mappings across 723 frameworks, 531 of them verified against their source documents. It does not tell you that you are compliant: a mapped control means the two standards ask for the same thing, not that you have done it.
