Unified threat management (UTM) or unified security management (USM), is the evolution of the traditional firewall into an all-inclusive security product able to perform multiple security functions within one single system: network firewalling, network intrusion detection/prevention (IDS/IPS), gateway antivirus (AV), gateway anti-spam, VPN, content filtering, load balancing, data loss prevention, and on-appliance reporting.

The worldwide UTM market was worth approximately $1.2 billion in 2007, with a forecast of 35–40% compounded annual growth rate through 2011. The primary market of UTM providers is small and medium-sized enterprises (SMEs), although a few providers are now offering UTM solutions for small offices/home offices
