Cisco ISA 3000 2C2F-K9= Industrial Security Appliance | Firewall — ISA-3000-2C2F-K9=

Keep industrial operations protected without adding complexity to the edge. Cisco Industrial Security Appliance 3000 brings firewall control to OT networks that need tight segmentation, reliable inspection, and a hardware profile suited to industrial deployments. With 2 copper ports and 2 fiber ports, it fits mixed-media environments where plant-floor connectivity must stay stable and secure. This appliance is designed for teams that need to separate control systems, remote access paths, and business networks while preserving performance in demanding conditions. It is a strong fit for substations, manufacturing cells, utilities, and distributed industrial sites where downtime carries real cost. The compact form factor makes it easier to place close to the assets it protects, reducing exposure at the edge. For organizations standardizing on Cisco security, the ISA 3000 offers a purpose-built option for industrial segmentation rather than a general-purpose office firewall. That distinction matters when the network must support operational continuity, controlled access, and a smaller attack surface across critical infrastructure. Ideal For Protecting manufacturing cell networks at the industrial edge Segmenting utility and substation traffic between OT zones Securing remote access paths into plant-floor systems Deploying firewall control in distributed industrial sites Why This Product 1 Built for industrial edge deployments rather than office networks 2 Combines 2 copper ports with 2 fiber ports for mixed-media connectivity 3 Compact hardware footprint suits close-to-asset placement 4 Cisco platform aligns with standardized enterprise security environments
