Cisco ISR 4351 3GE, 3NIM, 2SM, 4 GB Flash | Enterprise Router — CON-SSSW-C14351K9

Keep critical branch traffic moving with a router designed for enterprise WAN edge deployments. The Cisco ISR 4351 combines 3 Gigabit Ethernet ports with 3 network interface module slots and 2 service module slots, giving teams the flexibility to adapt connectivity, add services, and support changing site requirements without replacing the platform. Its 4 GB flash and 4 GB DRAM provide the memory foundation needed for routing services, configuration storage, and operational stability in business-critical environments. That matters when the router sits at the center of a branch, where uptime, policy control, and service continuity directly affect users and applications. This platform is a strong fit for organizations that need more than basic connectivity. It is built for sites that may require integrated services, future expansion, and a cleaner path to standardizing branch infrastructure across multiple locations. Compared with entry-level routers, the ISR 4351 offers more room for growth and a more durable fit for environments where network changes are routine and downtime is expensive.
