U.K.-based Sophos acquired Astaro in 2011 and phased out its name this year, calling the product Unified. Sophos UTM ships to the midmarket. The Security Gateway appliance can support from 45 Mbps to 575 Mbps of throughput. In addition to firewall capabilities, it includes Web filtering, endpoint protection and email security. It is available in a hardware or software version and as a virtual appliance. The company also sells a remote Ethernet device called Sophos RED, which extends the UTM capabilities to branch offices.
