Cybersecurity & Hardening

Cybersecurity in an operational technology (OT) environment is becoming increasingly important in view of growing digitalization and networking of production facilities and critical infrastructures. Automation Studio offers possibilities to increase resistance to cyberattacks and to secure operation.
