DORA Requirements 2025: The 5 Pillars of Digital Operational Resilience

The five pillars are ICT risk management (Art. 5‑16), ICT-related incident reporting (Art. 17‑23), digital operational resilience testing (Art. 24‑27), ICT third-party risk management (Art. 28‑44), and information sharing on cyber threats (Art. 45). Each pillar carries its own obligations, deadlines, and documentation requirements, but they interlock, for example findings from resilience testing feed directly back into the risk management framework.

DORA applies to nearly all regulated financial entities in the EU, from credit institutions to insurers to crypto-asset service providers, as well as their critical ICT third-party providers. The scope is deliberately broad; the extent of obligations actually owed scales through proportionality rules based on size, business model, and risk profile.

ISO 27001 provides a general framework for information security management, while DORA is sector-specific and legally mandates concrete obligations for financial entities, such as fixed reporting deadlines for ICT incidents or a mandatory third-party register. An existing ISO 27001 ISMS covers a substantial share of DORA requirements already, but doesn't replace DORA-specific obligations like the information register or the mandated third-party contract clauses.

Required documentation includes a documented ICT risk management framework, a continuously updated register of all ICT third-party contracts, and evidence of completed resilience tests and their results. This documentation needs to be verifiable and traceable for supervisory review; statements of intent without concrete evidence of measures actually taken generally don't hold up under review.

It's usually more effective to embed DORA requirements into existing risk management and IT governance processes rather than treating DORA as an isolated compliance project, for example by tracking ICT risk as its own category within the existing risk inventory instead of building a parallel structure. That reduces duplicate maintenance and keeps DORA reporting consistent with the rest of risk reporting.

Where requirements overlap substantively, for example on core risk management principles or incident reporting, processes and documentation can be reused rather than built separately, and an ISO 27001-certified ISMS or a NIS2 implementation project often delivers directly reusable building blocks for DORA. The key is applying whichever requirement is stricter or more specific as the standard, rather than defaulting to the lowest common denominator.
