ASA5505-50-BUN-K9 Overview
ASA5505-50-BUN-K9 is a desktop firewall appliance designed specifically for small business and branch office environments. Built as a hardware appliance, it features eight integrated 10/100 RJ-45 interfaces that can be configured as LAN ports along with a dedicated WAN port. The device delivers a firewall throughput of approximately 150 Mbps (0.15 Gbps) and VPN throughput around 50 Mbps (0.05 Gbps), making it well-suited for secure remote access and site-to-site VPN applications.
ASA5505-50-BUN-K9 supports core security services such as stateful firewall inspection, NAT, and VPN functionality while relying on Cisco’s ASDM and optional Cisco Security Manager for centralized configuration and monitoring. With a fixed capacity designed to support up to 50 users and with a desktop form factor powered by an external AC adapter (without redundant power supply), this appliance is optimized for small-scale deployments where simplicity, cost-effectiveness, and essential network protection are the primary requirements.
