C3845-H-VSEC/K9 Use Case
High-Throughput SSL VPN for Global Remote Workforce
In a multinational enterprise with 1,000+ teleworkers, the C3845-H-VSEC/K9 leverages AIM-VPN3/SSL and 1 Gbps forwarding to deliver secure, low-latency access to cloud and datacenter resources. Integrated AIS analytics ensure optimal application performance and threat detection, while 512 MB flash/1024 MB DRAM support concurrent sessions at scale. Outcome: seamless, enterprise-grade SSL VPN connectivity that boosts productivity, reduces support tickets, and strengthens corporate security posture.
Branch Voice Resiliency with CCME/SRST and PVDM2 DSP
A national retail chain deploys the C3845-H-VSEC/K9 at 200 branch locations to host Cisco CallManager Express and enable SRST via onboard PVDM2 modules. During WAN outages, local SRST routing sustains IP telephony services, preserving order-taking and customer support lines. Outcome: guaranteed voice continuity, minimized revenue loss, and centralized management with zero additional hardware.
Multi-Tenant Network Segmentation and Deep Packet Inspection
A service provider uses the C3845-H-VSEC/K9’s Performance VSEC virtualization to isolate five enterprise VPNs, enforce per-tenant security policies, and apply AIS-powered DPI for real-time threat intelligence. The modular platform scales to 512 MB flash/1024 MB DRAM for logging and rapid rule updates, ensuring SLA compliance. Outcome: secure multi-tenant architecture, enhanced visibility into application usage, and reduced breach risk.
