Case Study: Herzog Technologies secures dispersed OT, boosts WAN reliability, and cuts network staff by 50% with Fortinet

Fortinet Protects Widely Dispersed OT Equipment for Railroad Service Provider

Herzog Technologies (HTI), the communications and technology division of Herzog, manages mission‑critical OT and dispatch systems for railroads across the U.S. With equipment spread across data centers, dispatch centers and trackside base radio sites, HTI faced aging security appliances, an unreliable VPN and limited visibility — risks that could disrupt signaling, messaging and the safe movement of passengers and freight.

In partnership with Liquid Networx, HTI deployed Fortinet’s Security Fabric — including FortiGate NGFWs with Secure SD‑WAN, FortiManager, FortiAnalyzer, FortiSwitch, FortiExtender, FortiClient, FortiAP and FortiGuard services — using a standardized template for dispersed sites. The solution improved WAN reliability while lowering costs, delivered granular visibility and centralized management, reduced staff needs by about 50%, sped engineer onboarding 5x, and cut log‑analysis from hours to minutes.
