Our Competencies in Regulatory Compliance Management
Choose the area that fits your requirements
The NIS2 Directive requires effective cross-border cooperation mechanisms for critical infrastructures. We support you in the strategic implementation of coordinated security measures and incident response procedures at the EU level.
Important entities under NIS2 must meet the same cybersecurity requirements as essential entities under Article 21 — with reactive supervision and fines up to EUR 7 million. We guide you through classification, registration, and cost-effective compliance implementation.
The NIS2 Directive requires essential and important entities to report significant cybersecurity incidents in three stages. We help you build legally compliant incident reporting processes with clear 24h and 72h deadline management.
