The classification decision should be reviewable after the incident. Keep the operational evidence beside the legal conclusion so a later reviewer can see why the incident was reported, not reported, updated, aggregated, or reclassified.
The strongest record is a single evidence pack that links the SOC timeline, service-management timestamps, business-impact evidence, customer and counterparty counts, transaction baselines, loss estimates, communications, recovery measures, and competent-authority submissions.
When should a DORA incident classification form become a major-incident report?
When the incident affects critical services and meets the Article 8 test in Delegated Regulation (EU) 2024/1772: either successful malicious unauthorised access with possible data losses, or at least two other materiality thresholds. Recurring non-major incidents can also aggregate into one major incident when the regulation's recurrence conditions are met.
What fields should be ready for the first DORA initial notification?
At minimum, the form should hold the entity and contact fields, incident reference code, detection time, classification time, incident description, triggered classification criteria, impacted Member States, discovery route, available origin information, business-continuity activation status, and any other relevant information.
Can estimated numbers be used in a DORA incident classification form?
Yes. Delegated Regulation (EU) 2024/1772 allows estimates from comparable reference periods when affected clients, financial counterparts, transactions, or amounts cannot be determined, and Implementing Regulation (EU) 2025/302 allows estimated values where accurate data are not available for initial or intermediate reporting.
