Welotec’s IEC 61850-3-certified Rugged Substation Automation Computer (RSAPC) offers a hardened edge-server that consolidates HMI, gateway and engineering functions. Through Fortinet’s Fabric-Ready ecosystem, the RSAPC hosts a virtual FortiGate next-generation firewall alongside those workloads, adding deep-packet inspection for grid protocols such as IEC 61850 MMS/GOOSE and IEC 60870-5-104 without extra hardware.
Why utilities appreciate the joint solution
Both RSAPC and FortiGate Rugged models carry IEC 61850-3 / IEEE 1613 certifications, surviving –40 °C to +75 °C, vibration and surge events that would stop regular IT gear.
Spinning up FortiGate-VM on the RSAPC lets operators scale CPU, RAM or licence levels exactly to site needs while eliminating separate firewall boxes—cutting CapEx and truck rolls.
FortiGate’s industrial DPI engine recognises more than 1 700 OT protocols and commands. Utilities can, for instance, allow IEC 104 read operations but block remote-switching commands, or “virtually patch” legacy IEDs that can’t be updated.
FortiManager templates and Welotec’s device management services push rules, firmware and compliance checks to hundreds of dispersed substations from a central SOC.
Accelerating the energy transition—securely
Together, Welotec and Fortinet give grid operators a ready-made path to secure, virtualised substations: a hardened compute platform plus the industry’s most widely deployed OT cybersecurity stack. The result is faster commissioning, lower total cost of ownership and, above all, the confidence that critical power infrastructure is defended against evolving cyber threats.
As digital-substation roll-outs gather pace worldwide, Welotec and Fortinet will keep co-innovating—bringing AI-driven threat detection, zero-trust remote access and 5G connectivity to the edge of the grid.
