Fortinet :

fortinet’s award-winning FortiGate™ series of ASIC-accelerated Antivirus Firewalls are the new generation of real-time network protection systems. They detect and eliminate the most damaging, content-based threats from email and Web traffic such as viruses, worms, intrusions, inappropriate Web content and more in real time — without degrading network performance. The FortiGate systems deliver a full range of network-level services — firewall, VPN, intrusion detection and traffic shaping — as well as application-level services such as antivirus and content filtering, in dedicated, easily managed platforms.

A growing percentage of so-called "content-based" network attacks, such as viruses, worms and Trojans, are being introduced into organizations via seemingly innocuous activities such as Web browsing. This trend is expected to continue as organizations turn increasingly to real-time communications, like Web applications and instant messaging, as the means to remain responsive and competitive. Unfortunately, conventional network protection systems, such as firewalls and host-based antivirus software, lack the dedicated hardware required to perform the deep packet analysis, content reassembly, and application-level screening necessary to detect these threats without imposing unacceptable delays on real-time network applications. As a result, most organizations are dangerously exposed to content-based attacks from real-time traffic.

Fortinet’s FortiGate series of Antivirus Firewalls for the first time provides cost-effective systems that deliver complete network-level and content-level protection at the network edge with real-time performance. Each member of the scalable, flexible FortiGate family is a dedicated, easily managed device that delivers a full suite of capabilities, which include ICSA-certified virus protection and content filtering, along with network-level services including firewall, intrusion detection, intrusion prevention, VPN and traffic shaping functions.
