Cisco Industrial Security Appliance 3000 4-Port Managed Switch

The Cisco ISA-3000-4C-K9 is an industrial security appliance that delivers full switch management while keeping operational technology safe from cyber threats. It gives plant engineers, system integrators, and IT teams a single device that can both direct traffic and enforce security policy at the network edge.

Four gigabit Ethernet ports provide the bandwidth needed for high-speed data exchange between PLCs, sensors, and supervisory systems. By supporting network segmentation and Layer 3 security features, the appliance lets you isolate production zones, limit broadcast traffic, and reduce the chance of lateral movement inside the plant network.

The unit runs on a DC power source and snaps onto a DIN rail, so it installs quickly inside control cabinets or compact enclosures. A housing built for industrial conditions helps the switch tolerate vibration, dust, and temperature swings that would challenge office-grade equipment, allowing continuous operation in manufacturing, oil and gas, utilities, or transportation environments.

TAA compliance means the appliance meets federal procurement requirements, making it an easy choice for government projects or regulated industries that need to verify supply-chain sources while maintaining strong security and reliability.
