DORA requires a register of information for contractual arrangements on ICT services, and the register must distinguish arrangements that support critical or important functions from those that do not. The register is not only a reporting file; it is evidence for internal ICT risk management, supervision, and critical-provider oversight.
The register ITS turns the contract into structured data. For a contract supporting a critical or important function, the evidence package should include the contractual reference number, parties and identifiers, function identifier, ICT service type, direct provider, relevant subcontractors, service supply chain rank, substitutability assessment, last audit date, exit-plan status, reintegration possibility, discontinuation impact, and alternatives.
