What is NIS2?
EU Directive 2022/2555 on cybersecurity - the most significant overhaul of EU-wide cybersecurity regulation since 2016.
Overview
The NIS2 Directive (Directive (EU) 2022/2555) is the European Union's updated framework for achieving a high common level of cybersecurity across all Member States. It replaces the original NIS Directive from 2016.
NIS2 dramatically expands the scope of EU cybersecurity regulation - from approximately 10,000 entities under NIS1 to an estimated 160,000 across Europe. In Germany alone, roughly 29,500 companies are affected.
The directive mandates harmonized risk management measures, incident reporting obligations, and supply chain security requirements. It introduces personal liability for management and significantly higher penalties for non-compliance.
