As digital innovation initiatives dissolve the operational technology (OT) network boundaries, from IT networks (also known as the “air gap”), OT networks have become a target of a growing number of attacks. Application control and intrusion prevention (IPS) technologies that are integrated into every FortiGate Next-Generation Firewall (NGFW) can uniquely identify traffic from 55 different OT applications and protocols with more than 1,850 unique application control signatures to protect against advanced threats. In addition, IPS signatures can also virtually patch OT applications and protocols.
