Description
The Cisco Secure Firewall ISA3000 Industrial Security Appliance (ISA-3000-4C-K9) is a ruggedized, DIN-rail-mount firewall engineered to protect critical industrial and operational technology (OT) networks. Designed for harsh environments, it delivers enterprise-grade firewall and intrusion protection while supporting deep visibility into industrial protocols and applications.
Equipped with four Gigabit Ethernet copper ports, the ISA3000 enables secure segmentation of industrial zones, DMZ protection, and safe convergence of IT and OT networks. Its fanless, solid-state design ensures reliable operation in extreme temperatures, vibration-prone locations, and electrically noisy environments.
Built for utilities, manufacturing, transportation, oil and gas, and other industrial sectors, the ISA3000 supports advanced firewall inspection, VPN connectivity, industrial protocol awareness, and centralized or local management—making it an ideal foundation for industrial cybersecurity and compliance-driven deployments.
