DORA Details
What It Is
Digital Operational Resilience Act (DORA), formally Regulation (EU) 2022/2554, is an EU-wide regulation enhancing digital resilience of financial entities against ICT disruptions like cyberattacks and system failures. Applicable since January 17, 2025, it adopts a risk-based, proactive approach to harmonize rules across 27 member states, covering 20 financial entity types and critical third-party providers (CTPPs).
Key Components
- ICT Risk Management Frameworks: Identification, mitigation, and annual reviews.
- Incident Reporting: 4-hour notifications, 72-hour updates for major incidents.
- Resilience Testing: Annual basic tests, triennial TLPT for critical entities.
- Third-Party Oversight: Due diligence, monitoring, and ESAs supervision of CTPPs. Built on proportionality principle; enforced via RTS/ITS standards, no formal certification but authority audits.
Why Organizations Use It
- Legal mandate avoids fines up to 2% global turnover.
- Mitigates systemic risks (74% firms hit by ransomware).
- Boosts resilience, stakeholder trust, and cross-border efficiency.
- Drives cybersecurity investments amid threats like CrowdStrike outage.
Implementation Overview
Conduct gap analyses against ESAs RTS; develop frameworks, testing plans, vendor contracts. Tailored by entity size/complexity; key for EU financial sector. Preparation since 2023 involves training, tools, and simulations, with oversight fees up to €1M for CTPPs. (178 words)
