Lancope® PRESS RELEASE

Lancope Granted New U.S. Patent for Network Port Profiling

~Second Patent in 2007 for StealthWatch, the Most Widely Deployed Network Behavior Analysis System~

Atlanta, December 3, 2007 - Lancope®, Inc., the provider of the StealthWatch™ System, the most widely used network behavior analysis (NBA) and response system, today announced that U.S. Patent No. 7,290,283 has been issued for the company’s groundbreaking network port profiling invention, which delivers a more accurate and reliable method of detecting unauthorized network usage. Instead of relying upon signature databases of known attacks, which require ongoing maintenance to keep current, StealthWatch inspects all inbound and outbound activity and identifies new services not in compliance with host profiles. This innovative approach also enables StealthWatch to operate at much higher speeds than other detection systems.

This seminal patent covers StealthWatch’s pioneering port profiling system, which analyzes network communication traffic for unauthorized network activity. For example, StealthWatch can collect flow data from packet headers between two hosts or Internet Protocol (IP) addresses to verify that monitored flows are valid connections. StealthWatch then analyzes the collected flow data to determine the associated service provided and identify which network hosts act as a client and server for each valid connection. This revolutionary use of flow data provides unprecedented speed, accuracy and reliability for detecting and responding to network intrusions and abuse.

Earlier this year, Lancope was granted U.S. Patent No. 7,185,368 for its innovative flow-based detection of network intrusions.  A recognized provider of innovative technologies, Lancope has several pending patent applications that further expand on the use of flow-based analysis for network security monitoring and optimizing of network operations.

“Lancope remains committed to rapidly identifying and quickly responding to potential threats by developing innovative capabilities within StealthWatch,” said Harland LaVigne, president and CEO of Lancope. “This newly granted patent demonstrates Lancope’s continued leadership of the NBA market and exemplifies its pioneering efforts to provide customers with the accuracy, reliability and speed they need to protect and optimize their networks.

StealthWatch is the first and only flow-based solution to combine powerful network performance monitoring with real-time behavior-based anomaly detection to deliver total network visibility, ensuring security, optimal performance and availability. Unlike traditional perimeter-based security technologies, this patented flow-based approach enables cost-effective protection of hosts and networks without requiring probes, agents or continuous signature updates. A proven solution, StealthWatch now protects more than 30 million hosts worldwide and is deployed at hundreds of enterprise organizations across a variety of industry verticals, including Financial Services, Manufacturing, Federal Government, Healthcare, Energy and Higher Education. Notable customer acquisitions include AirTran Airways, OfficeMax, Cancer Research UK and the Internal Revenue Service.
