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.
Traditional point solutions, which were installed to
solve major threat and productivity issues, are often difficult to deploy, manage, and update, which increases operational complexities and overhead costs. The traditional point solution approach led to disadvantages, such as the deployment of reduced security and inferior policies at remote locations. UTMs can help overcome such problems. Instead, organizations of today may rely on an integrated approach to network security and productivity that combines the management of traditionally disparate point technologies.
