Framework overlap

Does ISO 27043 cover ISO 55001?

You hold ISO 27043 and have been told to do ISO 55001. Here is how much overlaps, control by control.

5% of ISO 55001 you already have

ISO 27043 already covers about 5% of ISO 55001, leaving 38 of 40 controls as genuinely new work.

Already covered 0 Likely covered 2 New work 38

No control in ISO 27043 maps directly to one in ISO 55001. 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 ISO 27043 reaches these. This is the list to scope.

How this is calculated

Already covered means a mapping runs from a control in ISO 27043 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.
