50% of ACSC Essential Eight you already have
Open Banking Security already covers about 50% of ACSC Essential Eight, leaving
12 of 24 controls as genuinely new work.
Already covered 0
Likely covered 12
New work 12
No control in Open Banking Security
maps directly to one in ACSC Essential Eight. 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 Open Banking Security reaches these. This is the list to scope.

How this is calculated
Already covered means a mapping runs from a control in Open Banking Security 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.
