How to protect it with unified threat management

What is UTM?

The term "unified threat management" (UTM) was first used by IDC Analyst Charles Kolodgy in 2003. This new term reflected the consolidation of technologies which, up to that point in time, performed separate security functions. Firewall, intrusion detection and intrusion prevention (IDS/IDP), and gateway antivirus, were now combined in a single, integrated network security appliance.

According to the Gartner Magic Quadrant for Unified Threat Management:*

Gartner defines the UTM market as multifunction network security products used by small or midsize businesses (SMBs). Gartner defines midsize businesses as those with 100 to 1,000 employees, and with revenue ranging from $50 million to $1 billion. However, the majority of midsize businesses' annual revenue is in the range of $100 million to $500 million, with head count ranging from 20 to 1,000 employees. UTM products for this market need to provide the following functions as a minimum:

  • Standard network stateful firewall functions
  • Remote access and site-to-site virtual private network (VPN) support
  • Web security gateway functionality (anti-malware, URL and content filtering)
  • Network intrusion prevention focused on blocking attacks against unpatched Windows PCs and servers

While historically attractive to SMBs, UTM is lately gaining traction with very large companies with hundreds of sites, where each site can have 1,000 or more employees.

UTM empowers network administrators and the teams they manage to work more efficiently and productively. It means not having to manage and update multiple point protection solutions from different vendors with varying GUIs, interfaces and management consoles.

UTM delivers everything a security professional requires—firewall, antivirus, web content and mail filtering, application control and networking functions like routing and load balancing—in a single appliance. It offers simple set-up, improved troubleshooting and a unified view of an organization’s security policy, reducing management costs and downtime.
