Cisco NGIPSv IPS and Apps on ISR 4451-120 Fixed SMS-1K | Security Licensing — FP4451A-TA-SMS-1K

Keep branch traffic under control with Cisco NGIPSv IPS and Apps licensing for the ISR 4451-120. This fixed SMS-1K package is designed for teams that need intrusion prevention and application-aware policy enforcement on an existing Cisco routing platform, without adding separate security appliances at every site. By extending security services directly on the ISR 4451-120, this license helps reduce hardware sprawl while preserving visibility into traffic patterns and application behavior. That matters in distributed environments where branch uptime, policy consistency, and operational simplicity all carry real cost. The fixed SMS-1K format supports a straightforward procurement and deployment model for standardized rollouts. It is a practical fit for organizations that want to align security capabilities with the router already in place, rather than funding a separate stack for every location. For IT teams managing remote offices, retail sites, or smaller regional hubs, this licensing option helps maintain a tighter security posture while keeping the network architecture predictable. It is the kind of purchase that makes sense when the goal is to protect critical traffic, simplify administration, and extend the value of the ISR platform already in service.
