Framework overlap

Does ISO 27019 cover PSD2 SCA?

You hold ISO 27019 and have been told to do PSD2 SCA. Here is how much overlaps, control by control.

67% of PSD2 SCA you already have

ISO 27019 already covers about 67% of PSD2 SCA, leaving 2 of 6 controls as genuinely new work.

Already covered 4 Likely covered 0 New work 2

What is genuinely new work

Nothing in ISO 27019 reaches these. This is the list to scope.

PSDTWO-5
Customer Authentication Methods, Biometric Controls, Device Binding
PSDTWO-6
Governance, Risk Management, Compliance Monitoring
Show the 4 you already have
PSDTWO-1
Strong Customer Authentication (SCA) Core Requirements
PSDTWO-2
SCA Exemptions and Risk-Based Authentication
PSDTWO-3
Common and Secure Communication, API Access for AISPs and PISPs
PSDTWO-4
Fraud Reporting and Incident Management

How this is calculated

Already covered means a mapping runs from a control in ISO 27019 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.
