Framework overlap

Does GDPR cover ISO/IEC 29134:2023?

You hold GDPR and have been told to do ISO/IEC 29134:2023. Here is how much overlaps, control by control.

10% of ISO/IEC 29134:2023 you already have

GDPR already covers about 10% of ISO/IEC 29134:2023, leaving 35 of 39 controls as genuinely new work.

What is genuinely new work

Nothing in GDPR reaches these. This is the list to scope.

How this is calculated

Already covered means a mapping runs from a control in GDPR 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.
