NIS2 Directive
The NIS2 Directive (EU 2022/2555) is an EU directive — the successor to the original NIS1 of 2016 — that entered into force on 16 January 2023 with a transposition deadline of 17 October 2024, meaning each EU Member State was required to adopt it into national law by that date and enforce it from 18 October 2024 onward. NIS2 is issued by the European Parliament and Council; as a directive (not a regulation), its exact requirements vary by Member State, but the baseline obligations are binding. It applies to medium and large organizations (50+ employees or €10M+ annual turnover) operating in 18 critical sectors including energy, transport, health, banking, digital infrastructure, ICT service management, public administration, and manufacturing. Entities are classified as essential (proactive supervision, fines up to €10M or 2 % of global turnover) or important (reactive supervision, fines up to €7M or 1.4 % of turnover). Compliance is mandatory — management bodies are personally liable for overseeing cybersecurity risk management. Key obligations include implementing proportionate technical and organizational security measures, conducting supply chain risk assessments, reporting significant incidents to the national CSIRT within 24 hours (early warning), 72 hours (full notification), and one month (final report), and cooperating with national cybersecurity authorities. Member States were required to publish their lists of essential and important entities by 17 April 2025.
