What is NIS2?

The EU NIS2 Directive (Network and Information Security 2) is a strengthened cybersecurity framework that broadens the scope of organizations required to implement security measures, report incidents, and ensure resilience. It introduces clearer accountability for management and tighter oversight from national authorities, with strict deadlines for compliance.

Why NIS2 Compliance Matters

  • €10M+ penalties for essential entities, €7M+ for important entities
  • Personal liability for senior management and board members
  • Mandatory incident reporting within 24 hours of detection
  • Supply chain security requirements for all vendors
  • Regular audits and continuous monitoring obligations

If your organization operates in critical sectors such as energy, finance, healthcare, telecom, or digital infrastructure, NIS2 likely applies to you. Compliance is more than a checklistit's a continuous program that reduces risk and safeguards essential services.

Why NIS2 Matters for Your Organization
