Framework overlap

Does ACSC Essential Eight cover BSI IT-Grundschutz?

You hold ACSC Essential Eight and have been told to do BSI IT-Grundschutz. Here is how much overlaps, control by control.

16% of BSI IT-Grundschutz you already have

ACSC Essential Eight already covers about 16% of BSI IT-Grundschutz, leaving 46 of 55 controls as genuinely new work.

Already covered 0 Likely covered 9 New work 46

No control in ACSC Essential Eight maps directly to one in BSI IT-Grundschutz. 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.

How this is calculated

Already covered means a mapping runs from a control in ACSC Essential Eight 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.
