ISR4461-SEC/K9 Use Case

Branch-Office Secure Connectivity and Threat Prevention with ISR4461-SEC/K9

A global manufacturing company with 50+ remote sites deploys Cisco ISR 4461 Security Bundles (ISR4461-SEC/K9) at each branch to consolidate WAN routing, VPN, next-generation firewall, IPS and URL filtering onto a single platform. Using DMVPN and IPsec tunnels, branch offices achieve secure, high-performance connectivity to headquarters and the Internet while deep-packet inspection and Cisco Advanced Malware Protection (AMP) prevent advanced threats. The integrated solution reduces hardware sprawl, enforces consistent security policies, and delivers up to 10 Gbps of encrypted throughput—cutting TCO by 30% and improving compliance with corporate security mandates.

Data-Center Edge Segmentation and Compliance Enforcement

A mid-sized financial services firm installs Cisco ISR 4461-SEC/K9 at its primary data-center edge to enforce PCI-DSS segmentation between payment processing, customer data stores, and corporate services. The ISR 4461 Security Bundle leverages zone-based firewalls, intrusion prevention, and next-gen threat intelligence to isolate sensitive workloads and monitor east-west traffic in real time. This high-throughput solution streamlines audit reporting, automates threat remediation, and ensures measurable security posture—helping the firm pass regulatory audits without deploying multiple point-products.

Secure Cloud On-Ramp and Hybrid-WAN Orchestration

A multinational retail chain uses Cisco ISR 4461 Security Bundles at regional hubs to extend secure, optimized connectivity to AWS and Azure as well as to branch locations. The ISR 4461-SEC/K9 delivers DMVPN-based hybrid-WAN orchestration, site-to-site IPsec, and per-flow application visibility with Cisco TrustSec identity enforcement. By inspecting cloud-bound traffic with NGFW, AMP, and SSL decryption, the retailer achieves unified security posture across on-premises and public-cloud environments, accelerates new store rollouts by 40%, and gains centralized policy control through Cisco DNA Center.
