This tool from ZyXEL is an appliance-based offering, which runs on a 1U rack-mounted device. It provides seven Ethernet gigabit interfaces, which can be separately addressed and configured. The ZyWALL USG300 is a stateful inspection firewall, which allows for deep packet inspection beyond the traditional packet filtering capability. The product is feature rich with built-in anti-virus and intrusion detection and intrusion prevention features. The unit's additional features include web caching, user authentication, content filtering and event alerting. The product offers many different types of failover, and even includes expansion ports so users can add a card for cellular backup of the primary WAN interface.
