According to IDC, UTM security appliance products include multiple security features integrated into one device. To be included in this category, as opposed to other Threat Management appliance segments, UTM appliances must contain the ability to perform network firewalling, network intrusion detection and prevention, and gateway antivirus. All of the capabilities need not be utilized, but the functions must exist inherently in the appliance. In addition to the mandatory applications, UTM appliances may also host other security or networking features.
