Cisco ISR 4431 4GE 3NIM 8G Flash 4G DRAM IPB | Enterprise Router — CON-SSSNE-38024SK9

Keep critical branch traffic flowing with the Cisco ISR 4431, a platform designed for secure WAN aggregation and service-rich edge deployments. Four Gigabit Ethernet interfaces provide the base connectivity needed for branch uplinks and LAN handoff, while three NIM slots give you room to add the interfaces and services your site requires. With 8 GB of flash and 4 GB of DRAM, this ISR is sized for enterprise routing tasks that need dependable local storage and memory headroom. It fits environments where network teams need more than simple connectivity: policy enforcement, segmentation, and room to grow without replacing the platform too early. The ISR 4431 is a strong fit for organizations standardizing on Cisco branch infrastructure and looking for a router that can support operational consistency across distributed sites. It is built for teams that value predictable deployment, long service life, and a platform that can absorb changing branch requirements without forcing a redesign. Ideal For Branch office WAN aggregation and routing Distributed enterprise edge connectivity Sites requiring modular interface expansion Cisco-standardized remote network deployments Why This Product 1 More expansion flexibility than fixed-port branch routers 2 Better suited for service-rich edge sites than entry routers 3 Cisco platform consistency for standardized branch rollouts 4 Memory and storage headroom for enterprise routing tasks
