Unified Threat Management (UTM) is a comprehensive solution that has recently emerged in the network security industry, and since 2004 it has gained widespread currency as a primary network gateway defense solution for organizations. In theory, UTM is the evolution of the traditional firewall into an all-inclusive security product able to perform multiple security functions within one single appliance: network firewalling, network intrusion prevention and gateway antivirus (AV), gateway anti-spam, VPN, content filtering, load balancing, data leak prevention and on-appliance reporting.
The worldwide UTM market was approximately worth $1.2 billion in 2007, with a forecast of 35-40% compounded annual growth rate through 2011. The primary market of UTM providers is the SMB and Enterprise segment, although a few providers are now providing UTM solutions for small offices/remote offices.
The term UTM was originally coined by market research firm IDC. The advantages of unified security lie in the fact that rather than administering multiple systems that individually handle anti virus, content filtering, intrusion prevention and spam filtering functions, organizations now have the flexibility to deploy a single UTM appliance that takes over all their functionality into a single rack mountable network appliance.

Famous quotes containing the words unified, threat and/or management:
“The man who knows governments most completely is he who troubles himself least about a definition which shall give their essence. Enjoying an intimate acquaintance with all their particularities in turn, he would naturally regard an abstract conception in which these were unified as a thing more misleading than enlightening.”

“An ill-trained doctor is a threat to life, an ill-trained priest a threat to faith.”

“The Management Area of Cherokee
National Forest, interested in fish,
Has mapped Tellico and Bald Rivers
And North River, with the tributaries
Brookshire Branch and Sugar Cove Creed:
A fishy map for facile fishery....”
