  • •The Cyber Resilience Act mandates new reporting duties for EU businesses.
  • •Reporting triggers include actively exploited vulnerabilities and severe incidents.
  • •Multiple reporting requirements can be triggered by a single cyber incident.

The Cyber Resilience Act (CRA) took effect on September 11, 2026, imposing new reporting obligations on manufacturers of hardware and software in the EU. This regulation requires reporting of actively exploited vulnerabilities and severe incidents affecting product security, regardless of personal data involvement. Businesses must navigate multiple reporting requirements triggered by a single cyber incident, which can include personal data breaches and service disruptions. The CRA introduces two reporting triggers: evidence of an actively exploited vulnerability and incidents compromising product security. Manufacturers must notify national Computer Security Incident Response Teams (CSIRTs) and affected users through ENISA's Single Reporting Platform. The rules aim to enhance cybersecurity resilience across the EU, with further obligations for open-source software stewards starting December 1, 2026.
