CRA 24-hour reporting: are your incident controls ready?

TL;DR: The EU Cyber Resilience Act will force covered manufacturers to report actively exploited vulnerabilities and severe incidents within 24 hours of awareness, shifting the challenge from fixing issues to proving rapid recognition, escalation and defensible reporting under pressure, according to ThreatLocker. The hard part is governance: teams must decide who can declare reportability before the clock starts.

Editorial analysis by NHI Mgmt Group, based on content published by ThreatLocker: “EU Cyber Resilience Act 24-hour vulnerability reporting begins Sept. 11”.

By the numbers:

• The first CRA reporting deadline arrives within 24 hours of awareness.
• Most other CRA obligations generally apply from Dec. 11, 2027.

Key questions

Q: What breaks when organisations do not define CRA reportability before an incident starts?

A: Teams lose time deciding whether an event is reportable, who owns the decision and what evidence is enough to act.

Q: Why does the EU Cyber Resilience Act create pressure for faster vulnerability triage?

A: Because the first notification deadline starts when the manufacturer becomes aware of a potentially reportable event, not when every investigation step is complete.

Q: How do security teams know whether CRA response is actually working?

A: They know it is working when they can identify an affected product, name an accountable owner, draft the notification, and prove corrective action inside a realistic tabletop window.

Practitioner guidance

• Build a 24-hour reportability decision path Assign named decision-makers, alternates and deadlines so an early warning can be issued without waiting for ordinary business hours.
• Document the awareness threshold for reportable events Define the evidence required for an initial assessment of actively exploited vulnerabilities and severe incidents, and record who can make the threshold call.
• Refresh product and component inventories Track covered products, legacy products, support status, software components and supplier contacts so teams can route notifications quickly.

Bottom line: The CRA turns vulnerability reporting into a time-bound governance test, with decision quality depending on how quickly teams can determine reportability.
