Framework overlap

Does GDPR cover Open Banking Security?

You hold GDPR and have been told to do Open Banking Security. Here is how much overlaps, control by control.

63% of Open Banking Security you already have

GDPR already covers about 63% of Open Banking Security, leaving 3 of 8 controls as genuinely new work.

Already covered 0 Likely covered 5 New work 3

No control in GDPR maps directly to one in Open Banking Security. 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 GDPR reaches these. This is the list to scope.

OPENBANK-1
FAPI 2.0 Security Profile and OpenID Foundation Conformance
OPENBANK-5
Data Minimisation, Scope Enforcement, Localisation, Cross-Border Transfers
OPENBANK-6
Fraud Detection, Transaction Risk Analysis, Rate Limiting, Sandbox
Show the 5 you already have
OPENBANK-2
Strong Customer Authentication (SCA), Consent Lifecycle, and Customer UX
OPENBANK-3
Mutual TLS, Token Binding, Request Signing (JWS), Key Management
OPENBANK-4
Third Party Provider (TPP) Onboarding, Directory Integration, Due Diligence
OPENBANK-7
Logging, Monitoring, Regulatory Reporting, SLA, Availability
OPENBANK-8
Incident Detection, Response, Customer Notification, Post-Incident Review, BCM

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.
