The EU's Software Security Clock Is Running: A 48-Day CRA Plan for Founders

01Executive summary

• CRA reporting begins on 11 September 2026, before the regulation's main product requirements apply in December 2027.
• The reporting duty covers affected products already available in the EU, not only products launched after the deadline.
• Downloadable software and connected hardware can be in scope. Standalone SaaS is generally outside it, but essential remote processing attached to a covered product may be included.
• Founders need one operating chain from detection to product scope, evidence, decision, regulatory notification, customer communication, and remediation.
• The immediate goal is not a large compliance programme. It is the smallest tested system that can make a defensible decision inside 24 hours.

02What changes on 11 September

The European Commission's CRA reporting guidance sets three stages. Manufacturers submit an early warning within 24 hours, then a main notification within 72 hours. A final report is due no later than 14 days after a corrective measure becomes available for an actively exploited vulnerability, or within one month of the 72-hour notification for a severe incident.

Reports go once through ENISA's Single Reporting Platform, which is scheduled to become operational with the obligation. The 24-hour report is an early warning, not a finished investigation. The business still needs enough reliable information to identify the product, affected markets, apparent severity, and immediate mitigation.

Importantly, the Commission says this reporting phase applies to products already made available in the EU. Waiting for the broader December 2027 compliance date creates a real gap.

03First decide whether your product is in scope

The CRA applies to "products with digital elements" made available on the EU market. That can include connected devices, desktop software, downloadable mobile apps, operating systems, plugins, and software components sold separately. A company does not escape the question because it is based outside the EU.

SaaS needs care. The Commission's implementation FAQ, updated in July, explains that standalone software-as-a-service is not itself a product with digital elements. But remote processing can fall in scope when the manufacturer is responsible for it and the covered product cannot perform a function without it.

Consider a smart access controller with a companion app and vendor-operated cloud service. The device, downloadable app, and essential remote processing may form one product-security boundary. A browser-only project-management service may reach a different conclusion. Product architecture, contracts, and distribution model matter, so obtain legal advice on the final scope.

04Why this is an engineering and operations problem

A regulatory form is the final step. The difficult work happens earlier: connecting a security signal to a shipped product and customer impact.

Log4Shell is a useful real-world example. A vulnerability in one widely embedded open-source component forced companies to ask which products contained it, which versions were deployed, and whether exploitation had occurred. Teams with a software bill of materials, release inventory, centralized logs, and clear product ownership could answer faster. Teams without them searched repositories and supplier emails while the risk evolved.

The same dependency problem appears in mobile SDKs, device firmware, authentication libraries, and white-label components. If the supplier sees exploitation first, your contract must support notification and evidence transfer quickly enough for your own reporting clock.

05The risks founders should manage

• Unknown product boundaries. Nobody can say whether a cloud service, app, firmware, and device are one reporting scope.
• Dependency blindness. The team knows a package is vulnerable but cannot map it to released versions and EU customers.
• Slow decision rights. Security, legal, product, and leadership all advise, but nobody is authorized to file the early warning.
• Conflicting communications. Engineering, support, customers, insurers, and regulators receive different facts because there is no shared incident record.
• Supplier delay. Contracts do not require timely vulnerability notices, logs, remediation details, or a named incident contact.

Article 64 allows fines for breaches of core manufacturer and reporting duties of up to €15 million or 2.5% of worldwide annual turnover, whichever is higher. The more immediate commercial risk is often loss of buyer confidence or delayed EU market access.

06A practical 48-day readiness plan

1. Map the portfolio. List every EU-available software product, connected device, component, companion app, and essential remote service. Record the manufacturer and distribution model.
2. Assign one accountable owner. Name the person who can start the CRA process, assemble security and legal input, and authorize the early warning.
3. Connect components to releases. Build or clean up the inventory that links dependencies, versions, deployment dates, customers, and support periods.
4. Create one incident record. Capture awareness time, evidence, affected product versions, EU availability, exploitation signals, severity, mitigations, decisions, and customer messages.
5. Repair supplier contracts. Require fast notification, evidence access, remediation cooperation, and named contacts for critical components and services.
6. Run a timed exercise. Simulate an exploited library in a released product. Demand a 24-hour warning packet, a 72-hour update, a customer notice, and a remediation owner.

Measure the drill in business terms: time to establish scope, percentage of affected customers identified, time to approve a mitigation, and unresolved evidence gaps. The result should become a funded product-security backlog, not a compliance slide deck.

07The opportunity: make security visible to buyers

CRA readiness can improve more than reporting. Enterprise buyers increasingly ask how quickly a supplier can identify affected versions, notify customers, and ship a fix. A tested response process, accurate component inventory, and explicit support commitments shorten security reviews and reduce avoidable sales friction.

Treat the work as product infrastructure. The same release and dependency data can support customer trust pages, procurement answers, incident response, support prioritization, and the full CRA requirements arriving in 2027.
