ÏFortinets latest FortiGate firmware, FortiOS 4.0, with newly-added features such as application control, WAN optimization, data leakage prevention and SSL inspection raised the competitive bar and has been met with enthusiasm and adoption from our customers across all segments, fueling further demand for our industry-leading FortiGate appliances, said Ken Xie, founder, president and CEO of Fortinet. ÏAs evidenced by IDC's latest numbers, Fortinet maintains its position at the leading edge of network security industry and is continuing to meet the needs of its rapidly growing global customer base.

According to IDC, UTM security appliance products include multiple security features integrated into one device. To be included in this category, as opposed to other Threat Management appliance segments, UTM appliances must contain the ability to perform network firewalling, network intrusion detection and prevention, and gateway antivirus. All of the capabilities need not be utilized, but the functions must exist inherently in the appliance. In addition to the mandatory applications, UTM appliances may also host other security or networking features.
