UTM (Unified thread management system) is a network security solution that evolved from traditional firewalls. It allows organizations to deploy a single appliance that performs multiple security functions like network firewalling, intrusion prevention, antivirus, anti-spam, VPN, content filtering, and reporting. The worldwide UTM market was worth $1.2 billion in 2007 and is forecasted to grow 35-40% annually through 2011. Purchasing criteria for UTM appliances include functionality requirements, pricing, flexibility in selecting features, and ongoing subscription costs.

1. UTM
(Unified thread management system)
Unified threat management (UTM) is a solution in the network
security industry, and since 2004 it has gained currency as a
primary network gateway defense solution for organizations.
[1] 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 segments, although a few providers are now
providing UTM solutions for small offices/remote offices.
[2] 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
antivirus, content filtering, intrusion prevention and spam filtering
functions, organizations now have the flexibility to deploy a single

rack mountable network appliance.
Purchasing Criteria
When it comes to making a purchasing decision, any UTM
appliances you consider will obviously have to tick the right boxes
in terms of offering the specific security functionality you require.
Beyond that, pricing and flexibility is a key differentiator. For a
given UTM, it is important to establish whether you will have to
pay for functionality such as email security even if you don't need
it, or whether you can select the security features you need. Don't
forget to look at the ongoing subscription costs (for anti-virus
signature updates, URL blacklists, support, and so on) as well as
the upfront cost.
