DORA Major ICT-Related Incident Report: [Incident reference]
A working file for classifying an ICT-related incident under the
Digital Operational Resilience Act (Regulation (EU) 2022/2554, DORA)
and for preparing the initial notification, intermediate report and
final report that Article 19 requires for major incidents. It follows
Commission Delegated Regulation (EU) 2024/1772 (classification criteria
and materiality thresholds), Commission Delegated Regulation (EU)
2025/301 (content and time limits) and Commission Implementing
Regulation (EU) 2025/302 (standard forms, with the data fields of its
Annex I and the glossary of Annex II). DORA applies from 17 January
2025; texts were checked on 2026-10-30, so check the consolidated texts
on EUR-Lex and your competent authority's reporting instructions before
use. Replace every [bracketed] value and every row marked Example.
This is a documentation format, not legal advice; check the current
official text and a qualified professional.

1. Scope and applicability
| Question | Answer | Source |
|---|
| Is the entity a financial entity under DORA Article 2(1)? | [Yes / No] | Authorisation or registration |
| Is the event an ICT-related incident (unplanned event that compromises the security of network and information systems and has an adverse impact)? | [Yes / No] | DORA Article 3(8) |
| Is it a payment-related operational or security incident for a credit institution, payment institution, account information service provider or electronic money institution? | [Yes / No] | DORA Article 23 |
| Does the incident originate at an ICT third-party provider? | [Yes / No, provider ID in the register of information] | Field 2.8 |
| Is the entity a microenterprise or subject to the simplified framework of Article 16? | [Yes / No] | Affects recurring incident rule (section 3.4) |
| Is the entity also an essential or important entity under NIS2? | [Yes / No] | Affects weekend rule (section 4.2) |
2. Roles, channels and authorisations
| Role | Person | Deputy | Responsibility |
|---|
| Incident commander | [@name] | [@name] | Runs the response, provides facts |
| Classification lead | [@name] | [@name] | Applies section 3, records the time of classification |
| Reporting lead | [@name] | [@name] | Drafts sections 5 to 8, tracks the clock |
| Authorised submitter | [@name] | [@name] | Submits through the authority's channel |
| Client communications lead | [@name] | [@name] | Section 9 |
| Data protection officer | [@name] | [@name] | GDPR breach assessment in parallel (section 12) |
Submit through the secure electronic channel the competent authority
provides. If that channel is unavailable, inform the authority through
other secure means agreed with it, and resubmit through the channel when
it is back if the authority asks (Implementing Regulation (EU) 2025/302,
Article 4). Significant credit institutions report to their national
competent authority, which passes the report to the ECB (DORA Article
19(1)). Member States may also require a copy to the NIS2 competent
authority or CSIRT.
3. Classification
3.1 Decision rule
Under Article 8(1) of Delegated Regulation (EU) 2024/1772, an incident is
major when it has affected critical services (Article 6) and
either:
- the data losses threshold for successful, malicious and unauthorised
access to network and information systems that may result in data
losses is met (Article 9(5)(b)), or
- two or more of the other materiality thresholds in Article 9 are met.
3.2 Criteria and thresholds
| Criterion (DORA Art. 18(1)) | How to assess (Delegated Reg. 2024/1772) | Materiality threshold (Art. 9) |
|---|
| Critical services affected | Art. 6: ICT services or systems supporting critical or important functions; authorised or supervised financial services; successful malicious unauthorised access | Gate condition for every major incident (Art. 8(1)) |
| Clients, financial counterparts and transactions | Art. 1: count clients and counterparts unable to use the service or adversely affected; transactions with at least one part carried out in the Union | Any of: clients over 10% of those using the service; over 100,000 clients; counterparts over 30%; transactions over 10% of the daily average number or over 10% of the daily average value; relevant clients or counterparts affected |
| Reputational impact | Art. 2: media coverage, repeated complaints, regulatory requirements likely not met, likely loss of clients or counterparts | Any one of the four conditions |
| Duration and service downtime | Art. 3: duration from occurrence to resolution; downtime from unavailability to restoration of the prior service level | Duration over 24 hours, or downtime over 2 hours for ICT services supporting critical or important functions |
| Geographical spread | Art. 4: impact on clients, counterparts, branches, group entities, market infrastructures or providers in other Member States | Impact in two or more Member States |
| Data losses | Art. 5: availability, authenticity, integrity, confidentiality | Adverse impact on business objectives or regulatory compliance (Art. 9(5)(a)), or malicious unauthorised access that may cause data losses (Art. 9(5)(b)) |
| Economic impact | Art. 7: direct and indirect costs and losses listed in Art. 7(1), gross of recoveries, excluding business-as-usual costs | Costs and losses exceed or are likely to exceed EUR 100,000 |
3.3 Classification worksheet
Example: Calderfield Payments S.A. card authorisation gateway, partial
outage after a failed certificate rotation at its hosting provider
(PROV-07 in the register of information). Figures for the affected
service: 48,000 merchant clients; daily average 1,250,000 transactions
worth EUR 61,500,000.
| Criterion | Evidence | Value | Threshold | Met at classification (2026-03-10 08:30) | Met at intermediate report |
|---|
| Critical services | Gateway supports a critical function (card acquiring) | Yes | Gate | Yes | Yes |
| Clients | 9,600 of 48,000 merchants (estimate, then actual) | 20% | Over 10% | Yes (estimate) | Yes (actual) |
| Transactions | 312,500 failed of 1,250,000 daily average; EUR 14,760,000 of EUR 61,500,000 | 25% by number, 24% by value | Over 10% | Counted with clients (same criterion) | Same |
| Reputational | National news coverage from 10:15, complaint surge | Media coverage | Any condition | No | Yes |
| Duration | Occurred 06:40 on 10 March, resolved 09:10 on 11 March | 26 h 30 min | Over 24 h | Not yet known | Yes |
| Service downtime | Unavailable 06:40 to 18:20 on 10 March | 11 h 40 min | Over 2 h | No (1 h 50 min elapsed) | Yes |
| Geographical spread | Merchants affected in LU, BE, FR, DE | 4 Member States | 2 or more | Yes | Yes |
| Data losses | No integrity or confidentiality impact found | None | Art. 9(5) | No | No |
| Economic impact | See section 8.3 | EUR 97,100 | Over EUR 100,000 | Not yet known | Not met |
| Result | | | Critical services plus 2 or more other thresholds | Major (clients and geographical spread) | Major (four criteria) |
Duration and downtime are one criterion, so meeting both counts once. The
same applies to clients and transactions.
3.4 Recurring incidents
Incidents that are not major on their own count as one major incident
when they occurred at least twice within 6 months, share the same
apparent root cause and together meet the Article 8(1) conditions
(Delegated Regulation (EU) 2024/1772, Article 8(2)). Assess this monthly.
The rule does not apply to microenterprises and to entities under the
simplified framework of DORA Article 16. Report recurring incidents in
aggregated form (Implementing Regulation (EU) 2025/302, Article 3).
| Month assessed | Candidate incidents | Same apparent root cause | Combined thresholds met | Result |
|---|
| [YYYY-MM] | [INC-IDs] | [Yes / No] | [List] | [Major / Not major] |
4. Reporting clock
4.1 Time limits (Delegated Regulation (EU) 2025/301, Article 5)
| Submission | Time limit | Trigger to update |
|---|
| Initial notification | As early as possible, within 4 hours of classification as major and no later than 24 hours after becoming aware of the incident | If classified as major more than 24 hours after awareness: within 4 hours of classification (Art. 5(2)) |
| Intermediate report | Within 72 hours of submitting the initial notification, even if nothing has changed | Updated intermediate report without undue delay when status or handling changes significantly, and in any case when regular activities have been recovered; also on request of the authority (DORA Art. 19(4)(b)) |
| Final report | No later than one month after the intermediate report or, where applicable, the latest updated intermediate report | When the root cause analysis is complete and actual figures replace estimates (DORA Art. 19(4)(c)) |
If you cannot meet a time limit, inform the competent authority without
undue delay and before the limit expires, with reasons (Art. 5(3)).
4.2 Weekends and bank holidays
Where a time limit falls on a weekend day or a bank holiday in the
reporting entity's Member State, the submission may be made by noon of
the next working day (Art. 5(4)). This relief does not apply to the
initial notification and intermediate report of credit institutions,
central counterparties, operators of trading venues and entities that are
essential or important under NIS2 (Art. 5(5)), and competent authorities
may remove it for other significant or systemic entities (Art. 5(6)).
Record which case applies: [Relief applies / Relief does not apply,
reason].
4.3 Worked timeline
| Event | Date and time (CET) | Deadline computed | Met |
|---|
| Incident occurs (field 3.2) (Example) | 2026-03-10 06:40, Tuesday | | |
| Detection and awareness (field 2.2) (Example) | 2026-03-10 06:52 | Initial notification no later than 2026-03-11 06:52 (24 hours after awareness) | |
| Classified as major (field 2.3) (Example) | 2026-03-10 08:30 | Initial notification by 2026-03-10 12:30 (the earlier of the two limits) | |
| Initial notification submitted (Example) | 2026-03-10 11:05 | Intermediate report by 2026-03-13 11:05 | Yes |
| Regular activities recovered (field 3.3) (Example) | 2026-03-10 18:20 | Updated intermediate report without undue delay | |
| Intermediate report submitted (Example) | 2026-03-11 15:00 | Final report one month later: 2026-04-11 15:00, a Saturday, so by noon on Monday 2026-04-13 under Art. 5(4) | Yes |
| Incident resolved (field 4.8) (Example) | 2026-03-11 09:10 | | |
| Root cause addressed (field 4.7) (Example) | 2026-03-20 17:00 | | |
| Final report submitted (Example) | 2026-04-08 10:00 | | Yes |
Calderfield Payments is a payment institution that is not an essential
or important entity under NIS2 in this example, so the weekend relief is
available; the team still planned the final report for a working day.

9. Informing clients
DORA Article 19(3) requires the financial entity, when a major incident
has an impact on the financial interests of clients, to inform them
without undue delay about the incident and the measures taken to
mitigate its effects. For a significant cyber threat, inform potentially
affected clients, where applicable, of protective measures they may
consider.
| Time | Channel | Audience | Message summary | Approved by |
|---|
| 2026-03-10 09:15 (Example) | Status page and email | Affected merchants | Outage, fallback options, next update time | [@comms-lead] |
| 2026-03-10 18:40 (Example) | Email | Affected merchants | Service restored, fee waiver for the day | [@comms-lead] |
| [Time] | [Channel] | [Audience] | [Summary] | [@name] |
10. Reclassification, joint and aggregated submissions
- Reclassification: if further assessment shows that a reported
incident never met the Article 8 conditions, notify the authority that
it is reclassified as non-major, using the "type of submission" and
"other information" fields (Implementing Regulation (EU) 2025/302,
Article 5).
- Joint submission: the initial, intermediate and final reports may
be submitted together where regular activities have recovered or the
root cause analysis is complete, provided each time limit is still met
(Article 2).
- Outsourced reporting: inform the authority of an outsourcing
arrangement before the first report (Article 6). The financial entity
remains fully responsible (DORA Article 19(5)).
- Aggregated reporting by a third-party provider: allowed only under
the conditions of Article 7, including that the incident originates at
the provider, affects entities in one Member State supervised by the
same authority, and the authority has permitted it. It is not available
to significant credit institutions, trading venues and central
counterparties.
11. Voluntary notification of significant cyber threats
A cyber threat is significant when all conditions of Article 10 of
Delegated Regulation (EU) 2024/1772 are met: it could affect critical or
important functions or other parties; it has a high probability of
materialising, considering vulnerabilities, threat actor capability and
intent, and persistence; and, if it materialised, it could meet the
critical services criterion or the clients or geographical spread
thresholds. The notification content follows Article 6 of Delegated
Regulation (EU) 2025/301 and the 20 fields of Annex III to Implementing
Regulation (EU) 2025/302.
| Annex III fields | Content |
|---|
| 1 to 11 | Submitting entity, financial entity, LEI, contacts |
| 12 | Date and time of detection |
| 13, 14 | Description and potential impact |
| 15 | Classification criteria that could be met |
| 16, 17 | Status and actions to prevent materialisation |
| 18 | Notification to other stakeholders |
| 19, 20 | Indicators of compromise, other information |
12. Other reporting regimes
| Regime | When it applies | Clock | Link |
|---|
| GDPR Articles 33 and 34 | Personal data breach | 72 hours to the supervisory authority where feasible; data subjects without undue delay if high risk | compliance/personal-data-breach-assessment |
| NIS2 | DORA is the sector-specific act for financial entities in its scope; Member States may require DORA reports to be shared with NIS2 authorities or CSIRTs (DORA Art. 19(1)) | As DORA | compliance/nis2-security-measures |
| Payment-related incidents | Credit institutions, payment institutions, account information service providers and e-money institutions report operational or security payment-related incidents under DORA (Art. 23) | As DORA | This template |
| Contracts and group policy | Client contracts, group reporting lines | [Contract terms] | [Reference] |
Check the consolidated texts for later amendments, including any change
to how and where incident reports are submitted.
13. Records, lessons learned and review
- Record every ICT-related incident and significant cyber threat in the
incident register required by DORA Article 17, whether or not it is
major.
- Keep copies of each submission, its acknowledgement and the evidence
behind each figure.
- Run a post-incident review and feed lessons into the ICT risk
management framework (DORA Article 13) and the business impact
analysis.
- Report major incidents and remediation status to the management body.
- Review this template and the classification worksheet after each major
incident and at least [annually].
