OT Cyber Security

Overview

As industrial systems become increasingly connected, the attack surface for operational technology (OT) environments continues to grow. Deftec provides comprehensive OT cybersecurity services designed specifically for the unique requirements of industrial control systems.

Our approach

We understand that OT security is fundamentally different from IT security. Availability and safety are paramount — our security measures are designed to protect without disrupting operations.

Assessment and auditing

We conduct thorough assessments of your OT environment, identifying vulnerabilities and providing actionable remediation plans aligned with frameworks such as IEC 62443 and the NIST Cybersecurity Framework.

Network segmentation

Proper network architecture is the foundation of OT security. We design and implement segmentation strategies that isolate critical control systems while maintaining necessary data flows.

Monitoring and response

Continuous monitoring of OT networks for anomalous behaviour, with incident response planning tailored to industrial environments where downtime has real-world safety and financial consequences.
