Threats against computer systems are more than a quarter century old, yet new and complex attacks by hackers (blackhat) continue to wreak havoc on today’s connected corporations. For more than two decades, firewall technology—and more recently point solutions such as virus detection and prevention, encryption and patch management—have helped to protect corporate information assets from computer criminals.

Organisations therefore need a unified approach that protects their networks and business users from blended attacks and technology misuse while decreasing operating costs. This ever-changing landscape of security threats has created a demand for Unified Threat Management (UTM) appliances.
UTM refers to a security device that provides broad network protection by combining multiple security features—firewalling, anti-virus, intrusion detection and prevention, and content control and filtering—on a single hardware platform. (The UTM acronym was coined by IDC.)Read Full Story
