Why OT needs its own firewall layer
While IT security focuses on protecting data, OT security prioritizes uptime, safety, and reliability. Firewalls secure OT environments by ensuring controlled data flow, enabling visibility, and enforcing strict access controls — and work best paired with network monitoring and a segmentation strategy.
IT/OT separation
Create strong separation between IT and OT networks, restricting access based on role, device, or protocol.
Threat containment
If an IT network is breached, an OT firewall prevents malware, ransomware, or unauthorized users from spreading into critical industrial systems.
OT-specific protection
Solutions like the Fortinet Rugged Firewall are built for harsh environments and include thousands of malware signatures tailored to OT-specific threats.
Protocol filtering
Enforce security policy at the protocol level — controlling industrial protocols, blocking unauthorized commands, and preventing lateral movement.
Firewalls at the IT/OT boundary
Firewalls at the DMZ and between ICS network zones inspect traffic with IPS signatures — virtually patching unpatched, vulnerable assets in controller and field networks.
