Fortinet has launched a new FortiGate unified threat management device aimed at mid-sized businesses.

FortiGate-620B is part of a refresh of the hardware used in Fortinet's line of multi-function security platforms and will eventually replace FortiGate-1000A, said the company.

The new UTM has a faster firewall than the older box -- 16Gbit/s vs. 4Gbit/s - and faster anti-virus screening at 250Mbit/s as opposed to 100Mbit/s for the older device. At US$16,000 (£9,820), the price of FortiGate-620B is $1,000 more than for FortiGate-1000A.

A feature of higher-end FortiGate boxes, network segmentation with unique policies, is included on the FortiGate 620-B

The devices can support antivirus, intrusion prevention (IPS), spyware prevention, antispam, web content filtering, traffic shaping, VPN and firewall. They compete against products by Juniper, Cisco, SonicWall, Watchguard and others.

The new FortiGate device has 20 Gigabit Ethernet ports, with an AMC expansion slot for four SFP firewall ports. The slot can also be used for a supplemental hard-drive module.
