The Cisco ISA-3000-2C2F-K9 from Cisco is a DIN rail-mount industrial firewall in compact form factor. It features two 1 Gigabit RJ45 and two 1 Gigabit SFP fiber interfaces, with switching capacity of up to 2 Gbps—minimum performance varies down to 22 Mbps depending on traffic type and security actions.

This model supports DC power input and includes four total data ports (two copper, two SFP). Designed for use in operational technology networks or industrial settings requiring Layer 3 routing capabilities alongside stateful packet inspection. The MAC address table holds up to 1,000 entries using its default TCAM template. Compatible with standard cybersecurity policies via integration within the Firepower Threat Defense architecture or IOS Firewall feature sets—it allows wall mount alternatives where DIN rails are not used.
