Framework overlap

Does ISO 27018 cover ISO 22318?

You hold ISO 27018 and have been told to do ISO 22318. Here is how much overlaps, control by control.

14% of ISO 22318 you already have

ISO 27018 already covers about 14% of ISO 22318, leaving 31 of 36 controls as genuinely new work.

How this is calculated

Already covered means a mapping runs from a control in ISO 27018 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.
