security appliance

In order to meet the increased security requirements in terms of defense against viruses, spam or worms, or to secure Internet telephony, specially equipped security appliances are used.

This is an appliance that, equipped with the appropriate software, can ward off certain threats. If the security appliance is equipped in such a way that it is only designed for a specific threat and performs a task within an overall system, it is referred to as a Specialized Security Appliance( SSA). In contrast, the Unified Threat Management Appliance( UTMA) handles all security solutions that can be caused by a wide variety of threats.
