Description
The Cisco ISA-3000-4C Industrial Security Appliance is a ruggedized, enterprise-grade firewall purpose-built for securing industrial and operational technology (OT) environments. Designed to operate reliably in harsh conditions, it delivers advanced threat protection, deep visibility into industrial protocols, and secure segmentation between industrial zones.
Equipped with four Gigabit Ethernet copper ports, the ISA-3000-4C supports flexible deployment at the network edge, in industrial DMZs, and across distributed facilities. It enables stateful firewalling, intrusion prevention, application visibility, and secure VPN connectivity while maintaining deterministic performance for critical control systems.
With fanless operation, extended temperature tolerance, and DIN-rail mounting support, the Cisco ISA-3000-4C is ideal for utilities, manufacturing, transportation, oil and gas, and other industrial environments requiring uncompromising security and resilience.
