The FortiGuard Operational Technology Security Service provides specialized intrusion prevention system (IPS) signatures to detect and block malicious traffic targeting applications and devices in manufacturing, plant, safety, and other operational technology (OT) environments. Combined with a FortiGate NGFW, malicious network traffic is blocked before causing harm by threat actors seeking to control or disrupt operations. In addition, the service can act as a virtual patch to provide immediate security protection until a vendor patch can be developed and deployed.
