What is Unified Threat Management

Unified Threat Management refers to a security solution that provides multiple security systems and functions in a single appliance. Components of UTM include firewalls, IDS and IPS systems, antivirus protection, gateways, VPNs, spam filters, and content filters.

What is Unified Threat Management (UTM)?

Security solutions can be differentiated between Specialized Security Appliances (SSA) and Unified Threat Management Appliances (UTMA). While Specialized Security Appliances are designed for specific security tasks, Unified Threat Management Appliances combine several security functions in a common platform.

UTM is thus able to provide security in a network through a single system in a central location. Different technologies are consolidated into one appliance and managed together. The operation of separate security products such as firewalls or IDS and IPS systems is no longer necessary.

Components of a UTM appliance include, for example, antivirus functions, spam filters, content filters, firewall functions, VPN functions, or intrusion detection and intrusion prevention functions. The advantage for administrators is that only one system needs to be installed and maintained.

UTM solutions from well-known manufacturers such as Check Point, Cisco, Fortinet, Juniper Networks, and Sophos are available on the market. If a powerful Unified Threat Management system is installed in the corporate network, company-specific security strategies or concepts can be implemented more quickly and with less administrative effort. The security architecture becomes integrative and bundles a multitude of functions under a common interface.

Common components of a UTM system

The architecture of Unified Threat Management solutions is service-oriented and provides comprehensive security functions that can be integrated into various applications and services. In addition to the network itself, the UTM system protects e-mail services, data transfers, databases, web servers, application servers or messenger, and short message services.

In order to perform all these tasks, the UTM appliance combines a wide variety of security solutions in a common, functionally combined solution. Components of a Unified Threat Management system can include the following individual functions and components:

  • Firewalls
  • Intrusion Detection Systems (IDS)
  • Intrusion Prevention Systems (IPS)
  • Anti-virus gateways, scanners, and protection systems
  • Internet gateways
  • VPN gateways (Virtual Private Network gateways)
  • Spam filters
  • Content filters
  • Proxy functions
  • Network Address Translation (NAT)
  • Authentication systems
  • Encryption systems
  • Quality of Service (QoS) functions
  • Reporting functions

Benefits of Unified Threat Management (UTM)

Unified Threat Management systems are becoming more and more important due to increasingly complex threat scenarios. Basically, different parts of the network and the IT environment can be attacked simultaneously with combinations of malware and different attack patterns.

If many different individual security systems are used in such attacks, which are managed and updated separately, the defense measures are only marginally effective. Especially when it comes to protection against new forms of malware, it is often almost impossible to bring systems from different manufacturers up to common current status.

Unified Threat Management offers the advantage of creating a central point for the defense against threats, which allows the uniform administration of all individual functions. Complex attacks can be defended more easily and the overall system is supplied with the latest defense strategies much more quickly.

The main advantage of the UTM solution is its ease of installation and use. Administrators can keep all security functions up to date at the same time and do not have to deal with hardware and software from different manufacturers. Another advantage is a lower investment and operating costs. The high costs caused by a complex security landscape can be avoided with a single UTM system, which is one reason why UTM systems are generally used primarily by smaller companies.
