NIS2 Directive — Mandatory since 17 October 2024

The EU NIS2 Directive (2022/2505/EU) significantly expanded the scope of affected companies and tightened security requirements. Mandatory measures include: risk management, incident reporting, supply chain security, and executive accountability. Cortexa helps you achieve full compliance.

Methodology

Security Program in 4 Steps

1
Identify
Asset inventory, network topology mapping, threat modeling (STRIDE). Business risk prioritization, critical system identification, and security gap definition.
2
Protect
Deploying security controls: access management, encryption, patch management, network segmentation, and endpoint protection. Policy and procedure development.
3
Detect & Respond
Continuous monitoring, anomaly detection, and incident management. SIEM deployment, playbooks, forensics capability, and post-incident review.
4
Recover & Improve
Business continuity plan, disaster recovery, regular security reviews, and continuous improvement of the protection program based on the evolving threat landscape.
