EU & UK References

Regulatory context (EU CRA / NIS2 / DORA / UK NIS Regulations)

NIS2 incident reporting (active exploitation)

Active exploitation triggers mandatory incident-reporting obligations under NIS2 Article 23 for EU operators of essential and important entities (24-hour early warning, 72-hour update, 1-month final report). UK NIS Regulations 2018 impose equivalent timelines on designated operators of essential services.

EU Cyber Resilience Act — coordinated disclosure

Critical and high-severity vulnerabilities in products with digital elements may trigger coordinated-disclosure obligations under the EU Cyber Resilience Act (CRA, Regulation 2024/2847). Manufacturers placing products on the EU market must notify ENISA and the relevant CSIRTs without undue delay once active exploitation is known.
