In this scenario, a national retail chain deploys the Cisco 1900 Engine Module ISM-SRE-300-K9 in branch routers to enable encrypted SD-WAN overlay, dynamic path selection and real-time WAN optimization. By offloading VPN and firewall workloads to ISM-SRE-300-K9, the retailer achieves up to 3 Gbps of secure throughput per location, 40% lower latency on cloud POS transactions and a 25% reduction in MPLS costs, ensuring seamless customer experience and centralized policy enforcement.
A regional telecom operator integrates the ISM-SRE-300-K9 Cisco 1900 Engine Module into its edge routers to host virtual network functions—firewall, DPI, and load balancer—without additional hardware. This deployment cuts service rollout from weeks to hours, scales to thousands of concurrent sessions at 5 Gbps aggregate throughput and reduces CapEx by 30%. The outcome is rapid, on-demand delivery of premium edge services with end-to-end orchestration and simplified operations.
In a smart factory environment, the Cisco ISM-SRE-300-K9 module is used to partition and inspect traffic between IT networks and operational technology (OT) segments. Leveraging built-in DPI and micro-segmentation, the plant enforces zero-trust policies on connected robots, sensors and controllers. The result is a 50% decrease in lateral threat exposure, compliance with industry security standards and uninterrupted production uptime through automated anomaly detection.
