Cisco NGFWv IPS and Apps on ISR 4351 | SMS-1K Security License — FTD4351-T-SMS-1K

Strengthen branch perimeter control without adding platform complexity. This Cisco entitlement enables NGFW, IPS, and application services on the ISR 4351, giving infrastructure teams a practical way to consolidate security functions on an existing router platform while maintaining policy consistency. The fixed SMS-1K designation points to a managed security model sized for 1,000 endpoints under Cisco security management. That makes it a fit for distributed sites that need centralized oversight, predictable licensing, and clear operational boundaries. Instead of layering separate appliances into every branch, teams can extend inspection and application control where the traffic already flows. For organizations standardizing on Cisco networking, this license helps align security procurement with the installed base. It supports a cleaner architecture for branch deployments, reduces the number of moving parts at the edge, and preserves the control plane discipline that matters when security policy must be enforced uniformly across sites. Ideal For Branch office perimeter security on ISR 4351 Centralized inspection and app control for distributed sites Managed security licensing for 1,000-endpoint environments Consolidating firewall and IPS functions into existing Cisco routing Why This Product 1 Adds security services to an existing ISR 4351 deployment 2 Combines NGFW, IPS, and app control in one entitlement 3 Fixed SMS-1K model supports 1,000 managed endpoints 4 Reduces the need for separate branch security appliances
