Severe incidents

What should the CRA severe-incident final report establish?

The final report needs the incident’s severity and impact, threat type or likely root cause, and mitigation details. Its one-month limit runs from the actual incident notification.

Prepared by CRA Operations · Updated 2026-09-13 · Hypothetical worked examples

The situation

A manufacturer has notified a severe incident and restored service. Its case file includes timing and mitigation, but the threat type or likely root cause has not been recorded. A recovery status should not hide that final-report gap.

Facts that change the answer

  • What was the actual timestamp of the incident notification?
  • What is known about threat type or likely root cause?
  • Are severity, impact and applied or ongoing measures documented?

Evaluated on 2026-09-13 using EU Cyber Resilience Act severe security incident notification record, version 2026.09.04. A completed example is not a customer Record or a declaration of conformity.

Evidence to keep

  • Actual incident-notification receipt
  • Investigation findings, including remaining uncertainty
  • Mitigation record, final report and user communications

Keep source artifacts in their controlled systems and record their references, responsible owner and review date with the decision.

Your next step

Prepare the report from the actual notification date and the available investigation findings. Keep the severe-incident sequence separate from vulnerability final-report timing.

Choose your real product or vulnerability case in the workspace. The selected assessment will be highlighted; example answers are not copied into your record.

Sources and application dates

Manufacturer reporting applies from 11 September 2026. Broader product requirements apply from 11 December 2027; these product-readiness examples support preparation. Open-source-steward obligations have their own application date.

These examples structure a decision and do not replace the Regulation, official guidance or product-specific professional advice. Not lawyer-reviewed.
