The company launched Version 7 of its RealSecure Network Sensor product for enterprise customers, and a new product called RealSecure Server Sensor for Microsoft's Internet Security and Acceleration (ISA) Server 2000, aimed at small to medium-sized businesses.
Version 7 of RealSecure Network Sensor has been developed to deal with the high-speed networks of today's enterprise customers, an ISS spokesman said.
The acquisition of Network Ice last year and integration of its BlackIce technology with RealSecure has created a product that can deal with the networks that today's customers are using, he said. "We've been able to do so in the past, but only through partnerships with other vendors," he said.
With its new enhanced drivers, RealSecure Network Sensor is capable of covering line speeds of 100Mbps and most Gigabit networks, the company said in a statement.
Seven layers of anomaly detection and attack pattern matching are used to interpret network activity, the statement said. The product can also use most of the rules from Snort, an open source intrusion detection system, it said.
RealSecure for ISA Server is designed to protect smaller businesses using Microsoft's ISA firewall and Web cache server. While the ISA server itself guards the network, controlling what traffic is allowed to pass, RealSecure for ISA Server continuously detects and responds to unauthorised or suspicious network behaviour, the statement said.
There is no need to run a separate server, because it resides on the ISA server, the statement added.
