What is the DORA ICT third-party register?

The DORA register of information is the record, required by Article 28 of Regulation (EU) 2022/2554, of all your contractual arrangements for the use of ICT services provided by third parties. Every financial entity must keep it current, maintain it at entity and, where relevant, sub-consolidated and consolidated group level, and make it available to its competent authority on request. It is the backbone of DORA's third-party risk regime: supervisors use it to see, across the financial sector, which providers the system depends on. The register is not a one-time inventory. It is a living record that has to reflect your ICT supply chain as it actually is, including which arrangements support critical or important functions, because those carry stricter contractual and oversight requirements. That distinction, critical-or-important versus the rest, drives much of what DORA asks of the relationship. The register documents each ICT contractual arrangement: the provider, the service, whether it supports a critical or important function, and the contractual terms DORA requires. The European Supervisory Authorities set the detailed template and fields through technical standards, so the precise columns are defined centrally rather than left to each entity. The register has to be complete and consistent enough that a supervisor can read your ICT dependency map from it. A register maintained as a spreadsheet, separate from the vendor relationships it describes, is accurate the day it is built and wrong the week a contract changes and nobody updates the file. That is the failure mode DORA's "keep it current" requirement is aimed at, and it is why the register cannot be a document you refresh before an inspection.
