This free DORA incident reporting checklist is for the compliance, operational risk and ICT teams of EU financial entities. One run covers one ICT-related incident: logging it, classifying it against the criteria and materiality thresholds of Delegated Regulation (EU) 2024/1772, telling senior management, deciding whether clients and personal data are affected, the initial notification, the intermediate report and its updates, the root cause and actual figures, the final report and its sign-off, and a post-incident review approved by the management body. Every due date counts from the date of detection. Tasks appear for an incident that is not major, a client notice, a possible personal data breach, a report sent by other means, a reclassification and a sign-off that asks for changes.

The Reporting Clock for One Incident

The Cybersecurity Incident Response Checklist runs the technical response, and the DORA ICT Risk Management Checklist reviews the whole framework every quarter. This checklist runs beside the response for one incident: the classification, the three reports to the competent authority, the client notice and the review, owned by the compliance or risk function. The Data Breach Response Checklist keeps the GDPR notice, which may run at the same time on its own clock.

The response

Incident response

Covers: containment, eradication, recovery and evidence for a security incident, in the Cybersecurity Incident Response Checklist.

Feeds: the timeline, impact figures and root cause that these reports need.

This checklist

DORA incident reporting

Covers: classification under Delegated Regulation (EU) 2024/1772, senior management, the initial notification, intermediate and final reports under Delegated Regulation (EU) 2025/301 in the template of Implementing Regulation (EU) 2025/302, the client notice and the post-incident review.

Ends: with the final report submitted and the improvements checked.

What the DORA Major ICT Incident Reporting Checklist Covers

Eight phases take one incident from detection to the final report, about four weeks later, and the review that follows. The first three phases are set out for the day of detection and the day after. The checklist halts at the management body’s approval in Phase 7, after every report to the authority has gone. Answers on the way add tasks for an incident that is not major, a client notice, a possible personal data breach, a report sent by other means, a reclassification and a final report that needs changes.

  1. Phase 1

    Phase 1: Detect, Log & Classify

    6 tasks

    Start the run as soon as an ICT-related incident is detected. The first task records the incident, the entity, the competent authority, the date of detection that every due date counts from, and the six people. Classification decides whether the reporting clock runs.

    • Open the incident record and name the people — the entity’s incident reference code, the financial entity and its LEI, the competent authority, the date and time of detection (every due date counts from the date), whether the weekend and bank holiday rule applies to you, and the six people; later tasks are assigned from these fields
    • Log the incident and start the timeline — what happened, when it occurred if known, when it was detected, how it was discovered, the services and systems affected, and whether it comes from an ICT third-party provider
    • Check whether critical services are affected — ICT services or systems that support critical or important functions, financial services that need authorisation or are supervised, or a successful, malicious and unauthorised access to your systems (Article 6 of Delegated Regulation (EU) 2024/1772)
    • Test the materiality thresholds — clients, financial counterparts and transactions, reputational impact, duration and service downtime, geographical spread, data losses and economic impact, each against its threshold in Article 9, using estimates where actual figures are not yet known
    • Record the classification decision and its time — major or not major, the date and time of the decision, who decided and why; the four-hour limit for the initial notification starts here when the incident is major
    • Record why the incident is not major and keep it under watch — the criteria and thresholds not met, the date to look again as the facts change, and the monthly check for recurring incidents that together may count as one major incident
  2. Phase 2

    Phase 2: Escalate & Check Who Else Must Know

    7 tasks

    On the day of detection or the next. Senior management hears of the major incident, the client and data protection questions are answered, and any other report or copy the law asks for is listed.

    • Report the incident to senior management — what happened, the classification, the reporting time limits and the response so far
    • Decide whether clients’ financial interests are affected — for example payments that failed or were delayed, funds that could not be reached, or costs clients may bear
    • Tell affected clients about the incident and the measures taken — without undue delay, the incident and the measures taken to limit its effects, through the channels in your crisis communication plan
    • Check whether personal data is involved — whether personal data was lost, altered, disclosed or made unavailable; the data protection officer decides whether a GDPR breach assessment starts
    • Run the GDPR breach assessment on its own clock — the GDPR notice is separate from the DORA reports, with its own authority and time limit; use your data breach response process and record the link to this incident
    • Brief the management body — a short first briefing now; the full account of impact, response and additional controls goes to it in Phase 7
    • List the other reports and copies that are due — copies your Member State asks for under NIS2, payment-related incident rules for credit, payment and e-money institutions, group or ECB routes, insurers and any contract that requires notice
  3. Phase 3

    Phase 3: Initial Notification

    5 tasks

    On the day the incident is classified as major: within four hours of classifying it and no later than 24 hours after becoming aware of it. Use the authority’s template and its secure channel.

    • Confirm the time limits and the weekend rule for this incident — the latest time for the initial notification, and for the intermediate report once it is sent, and whether a limit that falls on a weekend or bank holiday moves to noon of the next working day for you
    • Complete the initial notification in the authority’s template — the general information and the initial fields: reference code, detection and classification times, description, the criteria met, Member States affected, how it was discovered, its origin and whether a business continuity plan was activated
    • Submit the initial notification — through the secure electronic channel your authority provides, or, if that is not possible, by other secure means agreed with the authority
    • Record the authority’s reference code — the incident reference code the authority gives, quoted in field 3.1 of the intermediate and final reports, and the confirmation of receipt
    • Resubmit through the authority’s channel if it asks — once the channel works again, send the same notification through it so it is linked to the later reports
  4. Phase 4

    Phase 4: Intermediate Report & Updates

    7 tasks

    Within 72 hours of the initial notification, even if nothing has changed, then an updated report when regular activities recover and whenever the status changes significantly.

    • Update the impact figures — clients, counterparts and transactions affected, duration and service downtime, Member States, data losses and the functions and infrastructure affected, marked as actual or estimated
    • Complete the intermediate report — the intermediate fields of the same template: occurrence and recovery times, how the criteria were met, type of incident, threats and techniques, areas and infrastructure affected, impact on clients’ financial interests, other authorities told, temporary measures and indicators of compromise
    • Submit the intermediate report — at the latest 72 hours after the initial notification was submitted, linked to it in the authority’s channel; you may combine it with the initial notification if regular activities had already recovered and the time limits are met
    • Send an updated intermediate report when regular activities recover — without undue delay, and in any case when regular activities have been recovered, with the recovery time
    • Send further intermediate updates while the incident is open — an updated report each time the status changes significantly or the authority asks, and at least one a month until the final report; a correction goes in as a new version of the latest report
    • Review the classification with the facts now known — if the incident at no time met the criteria and thresholds for a major incident, it is reclassified as non-major and the authority told in the template
    • Submit the reclassification as non-major — the template with the type of submission “major incident reclassified as non-major” and the reasons in field 2.10; then mark the final report tasks not applicable
  5. Phase 5

    Phase 5: Root Cause & Actual Figures

    6 tasks

    The final report is due when the root cause analysis is complete and the actual impact figures replace the estimates, whether or not every fix is in place.

    • Complete the root cause analysis — the high-level, detailed and any additional root cause classification and the sequence of events that led to the incident
    • Record when the root cause was addressed and the incident resolved — both dates and times, the actions taken, and the permanent resolution date if it differs
    • Replace the estimates with actual impact figures — clients, counterparts, transactions, duration, downtime and data losses as finally measured
    • Total the costs, losses and financial recoveries — the direct and indirect costs and losses listed in Article 7 of Delegated Regulation (EU) 2024/1772, leaving out day-to-day costs, upgrades and insurance premiums, and the recoveries shown separately
    • Assess the information for resolution authorities — only for entities within Article 1(1) of Directive 2014/59/EU (for example credit institutions and investment firms): whether the incident posed a risk to critical functions or affected the resolvability of the entity or group; leave fields 4.10 and 4.11 blank if not, or if your entity is outside that Directive
    • Check for linked recurring incidents — other incidents in the last six months with the same apparent root cause that together meet the major incident criteria, reported in aggregated form
  6. Phase 6

    Phase 6: Final Report

    6 tasks

    No later than one month after the latest intermediate report. The senior manager signs off the report before it goes, but a sign-off never holds a report past its time limit.

    • Draft the final report in the authority’s template — the root causes, when they were addressed and the incident resolved, the resolution, information for resolution authorities, costs, losses and recoveries, and any recurring incidents, with every earlier field brought up to date
    • Check the final report against the earlier reports — identifiers unchanged, estimates replaced, amounts in thousands, the authority’s reference code in field 3.1 and the type of submission set to final report
    • Sign off the final report — the senior manager confirms the report is complete and accurate, or says what to change
    • Revise the final report and return it for sign-off — make the changes asked for, then ask the senior manager to change the decision to Approved; if the time limit is close, submit and send a correction later, or tell the authority before the limit
    • Submit the final report — through the authority’s channel, linked to the earlier reports, no later than one month after the latest intermediate report
    • Answer the authority’s questions and requests — questions on the reports, requests for an individual report, and, on request, the changes made after the post-incident review
  7. Phase 7

    Phase 7: Post-Incident Review & Approval

    5 tasks

    The review of what happened and what changes, reported to the management body. The checklist halts at the approval in this phase; every report to the authority comes before it.

    • Hold the post-incident review — whether procedures were followed and actions worked: the speed of the response and of judging severity, forensic analysis, escalation, and internal and external communication
    • Agree the improvements, owners and dates — changes to ICT operations, the business continuity policy, controls, the incident process and the reporting itself
    • Report the impact, response and additional controls to the management body — the incident, the reports made, the root cause, the costs and the improvements proposed
    • Approve the post-incident review and improvement plan — the management body member named on task 1 approves the review and the plan, or sends it back; the reports to the authority are already made
    • Rework the review and plan and return them for approval — address the reasons given, then ask the approver to change the decision to Approved, or to un-complete and complete the approval again
  8. Phase 8

    Phase 8: Lessons Learned & Close

    5 tasks

    The lessons go into the ICT risk assessment and the incident process, and the incident closes when the improvements are done and checked.

    • Feed the lessons into the ICT risk assessment — findings from this incident and from activating the continuity and recovery plans, as the basis for reviewing the ICT risk management framework
    • Update the incident process and reporting playbook — classification steps, contact lists, template guidance, channel access and the people who can submit
    • Track the improvements to completion — each action in the plan done, or moved with a reason recorded
    • Check the improvements worked — a test, an exercise or monitoring evidence that each fix closes the root cause
    • Close the incident record — reports, sign-offs, client notices, the review and the evidence kept together, and the incident marked closed in the log

Major Incident Thresholds and Reporting Time Limits

Under Article 8 of Delegated Regulation (EU) 2024/1772, an incident is major where it has affected critical services (Article 6) and either meets the unauthorised access threshold in Article 9(5)(b) or meets two or more of the other thresholds. The thresholds below are as Article 9 states them, read on EUR-Lex on 2 November 2026. This is a summary, not legal advice: the regulations and your authority’s instructions are the sources.

Criterion Threshold met when Article 9
Clients, financial counterparts and transactionsMore than 10% of clients using the service, or more than 100,000 clients; more than 30% of financial counterparts; more than 10% of the daily average number or value of transactions; or clients or counterparts identified as relevant are affected9(1)
Reputational impactThe incident is reflected in the media, causes repetitive complaints, means you will or are likely to miss regulatory requirements, or will or is likely to lose clients or counterparts with a material impact9(2)
Duration and service downtimeThe incident lasts more than 24 hours, or service downtime exceeds 2 hours for ICT services that support critical or important functions9(3)
Geographical spreadAn impact in two or more Member States9(4)
Data lossesAn impact on the availability, authenticity, integrity or confidentiality of data that harms the business objectives or regulatory compliance, or any successful, malicious and unauthorised access that may result in data losses9(5)
Economic impactCosts and losses exceed, or are likely to exceed, EUR 100,0009(6)

The reports and their time limits, as the sources say them:

Report Time limit Source
Initial notificationAs early as possible, within four hours of classifying the incident as major and no later than 24 hours after becoming aware of it; if it is classified as major later, within four hours of that classificationDelegated Regulation (EU) 2025/301, Article 5(1)(a) and 5(2)
Intermediate reportAt the latest 72 hours after the initial notification was submitted, even if nothing has changed; an updated report without undue delay, and in any case when regular activities recoverArticle 5(1)(b)
Final reportNo later than one month after the intermediate report or the latest updated intermediate report, once the root cause analysis is complete and actual figures replace estimatesArticle 5(1)(c); DORA, Article 19(4)(c)
A limit you cannot meetTell the competent authority without undue delay, and no later than the time limit, with the reasonsArticle 5(3)
Weekends and bank holidaysA limit on a weekend day or bank holiday may move to noon of the next working day, except for initial and intermediate reports by credit institutions, central counterparties, trading venues, NIS2 essential or important entities, and other significant or systemic entities their authority has toldArticle 5(4) to (6)
ClientsWithout undue delay, where the incident affects clients’ financial interests: the incident and the measures takenDORA, Article 19(3)
Form and channelThe template in Annex I with the glossary in Annex II, through the secure electronic channel the authority providesImplementing Regulation (EU) 2025/302, Articles 1 and 4

No amendment to these rules has been adopted: EUR-Lex lists no amending act for DORA, Delegated Regulation (EU) 2024/1772, Delegated Regulation (EU) 2025/301 or Implementing Regulation (EU) 2025/302 (only language corrections). The Commission’s Digital Omnibus proposal of 19 November 2025 (COM(2025) 837) would send these reports through a single entry point run by ENISA, without changing the time limits; on 2 November 2026 it was still before the European Parliament’s committees. The ESAs’ operational instructions of 16 September 2026 add reporting practice, and authorities publish their own: the Central Bank of Ireland’s page (updated 29 January 2026) links its template and its portal guide.

Why Run DORA Incident Reporting in CheckFlow?

1

Every report has an owner and a date

The classification, each report and the client notice go to the people named on the first task, with due dates counted from the date of detection. Each person sees their work in the Tasks Grid, and every incident sits in the Reports Grid with its progress.

2

The halt never holds a report

The senior manager signs off the final report without stopping the clock, and the checklist halts only at the management body’s approval of the review, after the last report has gone. Not approved adds a rework task. See how approvals that halt a checklist work.

3

The branches the law creates

Clients’ financial interests, personal data, a report sent by other means, a reclassification and a sign-off with changes each add their own task through conditional logic, and the weekend rule note matches your entity type.

CheckFlow runs the work around the reports: who does what and by when, the checks, the sign-offs and the evidence. It does not classify the incident for you, fill in the authority’s template or submit it; your team and your authority’s portal do that. The DORA Register of Information Checklist covers the yearly register, and CheckFlow for financial services shows other compliance workflows.

Frequently Asked Questions

When is an ICT-related incident major under DORA?

Under Article 8 of Delegated Regulation (EU) 2024/1772, an incident is major when it has affected critical services and either involves a successful, malicious and unauthorised access that may cause data losses, or meets two or more of the other materiality thresholds in Article 9. Those cover clients and transactions, reputation, duration and downtime, spread across Member States, data losses and costs over EUR 100,000. Recurring incidents with the same apparent root cause can together count as one.

When does the clock for the initial notification start?

Two limits run at once. The initial notification is due within four hours of classifying the incident as major, and no later than 24 hours after the entity became aware of it (Delegated Regulation (EU) 2025/301, Article 5(1)(a)). If the incident is classified as major more than 24 hours after awareness, the four hours run from that later classification. This template records both times on the first phase’s tasks.

What goes in the final report on a major ICT-related incident?

Article 4 of Delegated Regulation (EU) 2025/301 lists it: the root causes, when they were addressed and the incident resolved, how it was resolved, information for resolution authorities where it applies, direct and indirect costs and losses with any financial recoveries, and any recurring incidents. DORA says it is due once the root cause analysis is complete and actual figures replace estimates, even if fixes are still in progress.

Can a major incident be reclassified as non-major?

Yes, where further assessment shows it at no time met the criteria and thresholds for a major incident. Article 5 of Implementing Regulation (EU) 2025/302 says to notify the authority in the reporting template, choosing “major incident reclassified as non-major” as the type of submission and giving the reasons in the other information field. This template adds that task when the review in Phase 4 says so.

Do weekends and bank holidays extend the DORA reporting time limits?

Sometimes. A limit that falls on a weekend day or a bank holiday in your Member State may move to noon of the next working day. That does not apply to initial notifications or intermediate reports by credit institutions, central counterparties, operators of trading venues or NIS2 essential or important entities, and an authority may decide it does not apply to those two reports from other significant or systemic entities. Final reports can always use it.

When must clients be told about a major ICT-related incident?

Article 19(3) of DORA says that where a major incident affects the financial interests of clients, the entity informs them without undue delay as soon as it becomes aware of it, covering the incident and the measures taken to limit its effects. This template asks the question on the day of detection and adds the client notice task when the answer is yes.

Does a DORA incident report replace the GDPR breach notification?

No. If personal data is involved, Article 33 of the GDPR asks the controller to notify its data protection supervisory authority without undue delay and, where feasible, within 72 hours, unless the breach is unlikely to result in a risk to people. That is a separate notice to a separate authority. This template asks the data protection officer on day one and links the breach record.

Has the Digital Omnibus changed DORA incident reporting?

Not yet. The Commission’s Digital Omnibus proposal of 19 November 2025 would have financial entities send these reports through a single entry point run by ENISA, and would also change the GDPR breach notice. On 2 November 2026 it was still with the European Parliament’s committees, and EUR-Lex listed no amendment to DORA’s reporting rules. Check its progress before relying on this answer.
