Sophos XGS 4500
Higher-capacity 1U firewall for assessing inspected traffic and availability.

Overview
The XGS 4500 uses a 1U rack form factor and provides 4 × 1 GbE + 4 × 2.5 GbE + 4 SFP+ 10 GbE as fixed network interfaces. Consider this model when the network requires greater capacity in the 1U range and planning for redundant components. The appliance has dual SSDs with software RAID-1 support; a second internal power supply remains an option to be specified. The specification must distinguish integrated ports, optional modules and transceivers, and define licensing and continuity requirements.
