Alarm clock glowing red representing the CRA reporting obligations 24-hour deadline

Since 11 September 2026, manufacturers selling products with digital elements in the EU must act fast. They must send an early warning within 24 hours of becoming aware of an actively exploited vulnerability or a severe incident. A notification follows within 72 hours. The final report is due no later than 14 days after a fix or mitigation is available for a vulnerability, or within one month after the notification for an incident. Reports go through ENISA’s Single Reporting Platform.

That makes the EU Cyber Resilience Act a stopwatch, not a design conversation. Most teams prepare the reporting half: templates, owners, escalation paths. Few work on the four words that start the clock: “of becoming aware of it”.

What Do the CRA Reporting Obligations Require Since 11 September 2026?

The Cyber Resilience Act entered into force on 10 December 2024. Most of its requirements apply from 11 December 2027. Article 14, the reporting article, applied early.

It applies to every product that falls in scope, including products placed on the market before December 2027. Manufacturers carry three separate duties, and they run on different timetables.

Track one: an actively exploited vulnerability

An actively exploited vulnerability is one where there is reliable evidence that a malicious actor has exploited it without the system owner’s permission. When a manufacturer becomes aware of one in its product, it files an early warning within 24 hours.

A vulnerability notification follows within 72 hours. It carries the general nature of the exploit and any corrective or mitigating measures. The final report is due no later than 14 days after a corrective or mitigating measure is available.

Track two: a severe security incident

A severe incident affecting the security of the product triggers the same 24 hour early warning and the same 72 hour notification. The closing report has a different anchor. It is due within one month after the incident notification is submitted, not one month after the incident.

Track three: the people using the product

Separately from the regulator, the manufacturer must inform affected users, together with the corrective or mitigating measures they can apply. This duty has no fixed hour count attached to it, which makes it the one most likely to be handled last. If a manufacturer fails to inform users in time, the CSIRTs may do it for them.

How Does Reporting Work Since 11 September?

All regulatory reporting goes through one route. ENISA runs the CRA Single Reporting Platform, and it went live on 11 September 2026 as an initial operating capability. ENISA says it will expand the functions over the coming months.

The manufacturer reports once. The notification goes to the CSIRT of the member state where it has its main establishment, and ENISA gets access at the same time. A manufacturer with no main establishment in the EU is routed by the location of its authorised representative, importer, distributor or users, in that order.

The receiving CSIRT then shares the notification without delay with the CSIRTs of the other member states where the product is available. In exceptional cases, on justified cybersecurity grounds, a CSIRT may delay that onward sharing. The Commission adopted a delegated act on 11 December 2025 that sets the terms for those grounds.

The receiving CSIRT may also ask for an intermediate report with status updates. Open-source software stewards must report too, but only from 11 December 2027.

CRA Reporting Obligations Hinge on One Phrase: Becoming Aware

Read Article 14 closely and the trigger is not the exploitation, the disclosure or the patch. It is awareness.

Definition: Becoming awareThe 24 hours run from the moment the manufacturer becomes aware, which means the regulation measures something the manufacturer controls only indirectly.

This produces an uncomfortable asymmetry. A manufacturer with good external visibility learns about exploitation early, starts its clock early, and reports on a timeline that looks responsive.

A manufacturer with poor visibility may learn about the same exploitation weeks later from a customer, a journalist or a national CSIRT. Its clock technically starts on time, because it started when awareness arrived. But the exploitation has been running for weeks, other CSIRTs have not been warned, and users have not been told.

Article 14 starts the clock at awareness and says nothing about how fast a manufacturer should find out. That gap is a detection problem, and no reporting template closes it.

Why Is Awareness the Hard Part?

The gap between exploitation starting and a manufacturer noticing is not a paperwork problem. The window is narrow.

The exploitation window closes before most reporting windows open

Exploitation often comes before a fix exists. Then the ordinary disclosure process cannot warn the manufacturer, by definition.

Who Must Report, and What Does a Miss Cost?

Coverage follows the market, not the head office. The obligation attaches to manufacturers who make products with digital elements available on the EU market, wherever the company is established.

A vendor headquartered anywhere in the world that sells connected products into Europe is in scope. So is a company that sees itself as a software business, if what it ships is a product with digital elements.

The exposure sits in the highest penalty tier. Breaching Article 14 can bring administrative fines of up to EUR 15,000,000 or 2.5% of total worldwide annual turnover for the preceding financial year, whichever is higher. That tier covers the essential cybersecurity requirements too, so reporting is not a lesser duty. It makes CRA reporting obligations a board-level risk item, not a documentation task.

What Should You Do in the First 24 Hours?

Once someone inside the company suspects active exploitation, work through these steps in order.

  1. Record the time, the person and the evidence at the moment of awareness.
  2. Check the evidence against the legal test: reliable proof that a malicious actor exploited the weakness without permission.
  3. Send the early warning through the Single Reporting Platform, listing the member states where the product is available.
  4. Prepare the 72-hour notification: affected product, nature of the exploit, and measures taken or advised.
  5. Tell affected users what they can do, and plan the final report.

How Can You Close the Awareness Gap?

The reporting workflow is the easy half. The awareness half needs work that looks nothing like compliance work, and meeting CRA reporting obligations depends on solving it first.

Know what you actually shipped

The 24 hour clock applies to products already on the market, including versions shipped years ago and still deployed. An inventory of what you support is not an inventory of what is running, and Article 14 cares about the second one.

Watch the product from the outside

Internal telemetry covers the instances you operate. It says nothing about the customer deployments that make up most of your installed base. Finding exposed instances of your own product from the outside, including versions you no longer support, is the most direct way to shorten the gap.

Monitor where exploitation is discussed before it is disclosed

Exploit code, access listings and target lists circulate in closed forums and marketplaces well before a coordinated disclosure lands in your inbox. Where exploitation precedes disclosure, this is often the only channel through which awareness can arrive in time.

Decide now who is allowed to say the word aware

Awareness is a legal state with a 24 hour consequence. The moment it is reached should be a named decision by a named role, recorded with a timestamp. Left undefined, it becomes a question a regulator answers after the fact, which is the worst time to answer it.

Frequently Asked Questions.

When do the CRA reporting obligations start?

They have applied since 11 September 2026. The main requirements of the Act apply later, from 11 December 2027.

How fast must a manufacturer report an actively exploited vulnerability?

An early warning is due within 24 hours of becoming aware and a full notification within 72 hours. The final report is due no later than 14 days after a corrective measure is available.

Where do manufacturers send CRA reports?

They report once through the CRA Single Reporting Platform. The CSIRT of the member state where the manufacturer has its main establishment receives it, and ENISA gets it at the same time.

Do the rules cover manufacturers outside the EU?

Yes. The Act covers products made available on the Union market, whatever the location of the manufacturer.

What must a CRA early warning contain?

It must be sent within 24 hours of becoming aware. It lists the member states where the manufacturer knows the product is available. For a severe incident, it also says whether unlawful or malicious acts are suspected.

What is the CRA final report deadline?

For an actively exploited vulnerability, no later than 14 days after a corrective or mitigating measure is available. For a severe incident, within one month after the 72-hour notification is submitted.

Do open-source projects have to report under the CRA?

Open-source software stewards must report from 11 December 2027, to the extent they are involved in developing products with digital elements. Manufacturers' own reporting duties have applied since 11 September 2026.

What counts as an actively exploited vulnerability?

The Act defines it as a vulnerability for which there is reliable evidence that a malicious actor has exploited it in a system without the permission of the system owner.
