Corrent, of Tempe, Ariz.,\u00a0used to make just processors and security acceleration boards but now it has joined the roster of companies that sell Check Point firewall\/VPN software loaded onto dedicated hardware appliances.Called SR500 and SR600, Corrent's two devices come with Check Point VPN-1\/Firewall-1 software and the company claims the products pack enough processing power to keep them from being swamped during denial-of-service attacks.The company says the devices can block\u00a0denial-of-service attacks at 1G bit\/sec while allowing nearly the same amount (949M bit\/sec) of good traffic to pass through.Corrent's architecture breaks down security processing into separate operations that are handled by separate processors. A Corrent security processor handles IPSec, two Intel Xeon processors runs Check Point's Layer 7 Application Intelligence, and a network processor handles packet processing. The chassis is a rack-mounded IBM xSeries server running Linux.Corrent says it built its gear for speed, and that it supports 50,000 firewall connections per second and can handle up to 1 million simultaneously. The company also claims it can support up to 20,000 VPN tunnels.The SR600 costs between $39,900 and $45,000, depending on the number of ports. It supports up to nine accelerated 10\/100\/1000 Ethernet ports and comes with two non-accelerated ports for box-to-box communication and out of band management. SR500 costs between $35,900 and $40,000, and can come with up to five accelerated and two unaccelerated ports.Corrent is three years old, and in that time has developed security chips and a security-acceleration board that is sold by Check Point under the name Secure XL Turbocard.While you might not have heard of Corrent before, the fact that it has a track record in security hardware and is piecing together its appliances from known commodities make these devices something to consider if you are in the market for firewall\/VPN gear in this category.
