LAS VEGAS--(BUSINESS WIRE)--May 7, 2001

Enhanced CaptIO-G with Two Gigabit Ports Is Unique in Providing the

Throughput to Protect High-Speed Distribution Switches and Routers

Captus Networks today announced important enhancements to its CaptIO-G(TM) network security device that make it the first security solution capable of stopping Denial of Service (DoS) attacks against high-volume Internet networks. In a design implementing high-bandwidth bus architecture, the newest CaptIO-G model achieves the multi-Gigabit throughput necessary to protect the high-speed distribution switches and routers in service provider and enterprise networks.

The CaptIO-G device now provides two high-performance Gigabit Ethernet interfaces that utilize 66 MHz PCI technology -- representing a significant throughput upgrade to the current single-Gigabit model -- in a space-saving 1U rack-mountable format. Unique in the network security device marketplace, the CaptIO-G device integrates a policy-based Traffic Limiting Intrusion Detection System (TLIDS(TM)) and firewall technology to provide unprecedented control in managing all traffic, including potentially devastating Denial of Service (DoS) and Distributed DoS (DDoS) attacks that attempt to overwhelm Web servers with a flood of bogus network packets.

"As we become an increasingly digital economy, business models become wholly reliant on their networks. But often network service providers and e-businesses have had to choose speed over safety. The CaptIO-G network security device makes this tradeoff a thing of the past," said Richard G. Helgeson, CEO and president of Captus Networks.

DoS and DDoS Attack Protection

The CaptIO-G device uses proprietary and patent-pending technology to identify and stop DoS attacks within seconds of detection, without disrupting legitimate network traffic. The device enforces security policies regardless of whether the abusive activity originates from outside or inside the network. Many network security breaches occur within networks and the CaptIO-G device provides a higher level of security than systems that focus only on blocking hostile external activity. This capability is valuable to service providers and data center managers by preventing their networks from being used as the source of outbound DDoS attacks.

The CaptIO-G includes two Gigabit Ethernet (1000BASE-SX) interfaces, four Fast Ethernet (10/100BASE-TX) interfaces, and one Fast Ethernet management interface in a low-power, 1U rack-mountable chassis. Each individual interface on the CaptIO-G device can have its own set of firewall rules and TLIDS policies. This capability allows service providers offering managed security services to offer complete security solutions to multiple customers using only a single device.

CaptIO-G device management is through a Command Line Interface (CLI) or a Web Management Interface (WMI) that is secure and encrypted across the entire network to ensure that malicious users cannot "sniff" critical data.
