CISCO3825 Use Case
Branch Office WAN Aggregation and Secure Connectivity with Cisco 3825
In a mid-size enterprise, IT deploys the CISCO3825-3825 w/AC PWR, 2GE,1SFP, 2NME, 4HWIC, IP Base, 128F/512D at each branch to aggregate local LAN, encrypted VPN tunnels, and MPLS circuits. By leveraging its dual Gigabit Ethernet ports and SFP uplink, the router delivers high-throughput site-to-site encryption using NME crypto modules, while HWIC slots host voice and security appliances. Outcome: Centralized management reduces WAN costs by 30%, ensures end-to-end data privacy, and scales to 250+ remote sites without performance degradation.
DMZ Application Delivery and Network Segmentation
A financial institution implements the CISCO3825-3825 w/AC PWR, 2GE,1SFP, 2NME, 4HWIC, IP Base, 128F/512D to isolate public-facing services in a secure DMZ. Using its four HWIC slots for next-gen firewall and intrusion-prevention modules, alongside redundant power and SFP fiber links, the router enforces strict access control policies. Benefit: Achieves PCI-DSS compliance, reduces attack surface by 45%, and maintains sub-millisecond firewall throughput under peak load, ensuring uninterrupted customer transactions.
Industrial Automation and Remote Site Connectivity
A manufacturing plant integrates the CISCO3825-3825 w/AC PWR, 2GE,1SFP, 2NME, 4HWIC, IP Base, 128F/512D to connect PLCs, SCADA systems, and VoIP phones across remote substations. The router’s real-time QoS and mission-critical NME modules prioritize control-plane traffic over fiber and Ethernet links. Outcome: Delivers deterministic latency below 5 ms for control signals, boosts operational uptime to 99.99%, and simplifies firmware rollouts across 50+ remote nodes via Cisco IOS automation.
