The NIS2 Directive represents the most significant overhaul of EU cybersecurity legislation in a decade. With stricter requirements, broader scope, and substantial penalties, understanding its impact on your business is no longer optional—it’s essential.
EU Member States have transposed NIS2 into national law. Deadlines are now in effect across the EU. This guide reflects the latest implementations and official guidance.
What is the NIS2 Directive?
The Network and Information Systems Directive (NIS2) – Directive (EU) 2022/2555 is the EU’s flagship cybersecurity legislation. It replaced the original NIS Directive (NIS1) on October 18, 2024, with Member States required to transpose it into national law by that date.
Key Objectives
Harmonize cybersecurity requirements across EU Member States, improve incident response, and ensure management accountability for cyber risks.
Scope Expansion
From 7 to 18 sectors, including manufacturing, food, digital providers, and public administration. Medium-sized enterprises are now explicitly covered.
Enhanced Penalties
Essential entities: €10M or 2% global turnover. Important entities: €7M or 1.4% global turnover. Management faces personal liability.
Your NIS2 Compliance Journey
Does NIS2 Apply to Your Company?
Even if your company is below the size thresholds, you may still be in scope if you operate in critical sectors or are part of the supply chain of essential entities.
Essential vs. Important Entities
NIS2 introduces a two-tier classification system with different requirements and penalties:
| Category | Essential Entities | Important Entities |
|---|---|---|
| Sectors | Energy, Transport, Banking, Financial Markets, Health, Drinking Water, Digital Infrastructure | Postal, Waste Management, Chemical, Food, Manufacturing, Digital Providers |
| Size Threshold | 250+ employees OR €50M+ turnover | 50-249 employees OR €10M-€50M turnover |
| Maximum Fine | €10,000,000 or 2% global turnover | €7,000,000 or 1.4% global turnover |
| Supervision | Ex-ante (proactive) supervision | Ex-post (reactive) supervision |
| Inspection Frequency | Regular, mandatory audits | Risk-based, less frequent |
