NIS2 is no longer just for large enterprises

NIS2 extends to companies with 50+ employees in essential and important sectors.

Key obligations

  • Cybersecurity risk management policy
  • Technical security measures
  • Incident notification within 24h (alert) and 72h (report)
  • Management liability
  • Supply chain security
  • Key Takeaways
