Commission Delegated Regulation (EU) 2025/301
Digital Operational Resilience Act (DORA)
Objective: This RTS defines the precise content and timelines for notification of major ICT incidents to supervisory authorities, as well as the voluntary notification process for significant cyber threats.
Key Principle: Fast, progressive and structured notification in 3 stages:
Incident Reporting Flow: from Detection to Final Report
All three reports submitted via national competent authority channel (EIOPA/EBA/ESMA depending on entity type). Times are maxima: earlier is always permitted.
Work through each question. One "YES" to Q1–Q6 makes the incident major and triggers the T+4h notification obligation.
Failure to meet deadlines constitutes a DORA violation subject to administrative penalties set by national law under Article 50.
Deadline: Maximum 4 hours after classifying the incident as "major"
Objective: Alert the supervisor that a major incident is ongoing
Minimum mandatory content:
⚠ Information NOT required at this stage:
Tip: Prepare a pre-filled template with static information (entity identification, contacts, etc.) to save time during emergency notification.
Deadline: Maximum 72 hours (3 days) after initial detection
Objective: Provide a detailed update on the situation and impact
Mandatory content:
Important note: If the incident is not resolved at T+72h, the interim report must include an action plan with expected timeline.
Deadline: Maximum 1 month (30 calendar days) after initial detection
Objective: Provide comprehensive post-incident analysis and preventive measures

At T+72h (Interim Report):
At T+1 month (Final Report):
Principle: In addition to the obligation to notify major incidents, financial entities MAY voluntarily notify significant cyber threats they detect, even if no incident has (yet) occurred.
| Information | Description |
|---|---|
| Threat type | Malware, phishing, DDoS, intrusion, vulnerability, etc. |
| Technical indicators |
• Malicious file hashes (MD5, SHA256) • Source IP addresses • C2 (Command & Control) domains • Malicious URLs • Attack patterns |
| Attack vector | Email, web, API, VPN, supply chain, etc. |
| Targeted systems | Targeted applications, OS, network equipment |
| Sophistication level | Low / Medium / High / APT |
| Defensive actions taken | Blocks, isolations, patches, enhanced monitoring |
⏰ Voluntary notification timeline:
No strict deadline imposed, but notification recommended as soon as possible to maximize the usefulness of the information for the sector.
Best practice: Notify within 24h of threat detection, even if analysis is not complete.
