ClearSight Gigabit Analyzer Chosen Over Competition for Its

Superior Network and Application Analysis

and Troubleshooting Capabilities

ClearSight Networks, the first company to offer network analysis tools for troubleshooting at the application layer, today announced that CMP Media LLC's Network Computing has selected ClearSight Analyzer Gigabit as a winner for the 10th Annual Well-Connected Awards in the Network Diagnostic Tool category. The awards profile the best networking products tested in Network Computing's Real World Labs in 2003.

"The Well-Connected Awards are the only industry awards given by technologists based on real-world product testing and evaluation. We view all products, technologies and services from the same perspective as our readers -- our peers -- do," said Fritz Nelson, VP and Group Publisher of Network Computing Enterprise Architecture Group. "This is an important distinction from any other award program -- the products selected in the Well-Connected Awards are unique because they have been tested over an enterprise by our editors themselves. They are truly innovative solutions that work."

ClearSight Gigabit Analyzer enables application and network professionals to visualize network problems as the user sees them, eliminating the need for complicated packet decodes. By delivering a tool that does not require the technical expertise of traditional analyzers, ClearSight enables multiple departments across an enterprise -- from network administrators to database administrators -- to quickly pinpoint network problems in real-time, leading to more effective use of resources and high-availability business critical applications.

"Being named a winner of the prestigious Network Computing Well-Connected Award validates ClearSight's leadership within the network analysis market," said Tom Orr, president of ClearSight Networks. "We're committed to delivering unprecedented application and network troubleshooting capabilities to our customers and we're working tirelessly to push for innovative solutions in the marketplace."

The ClearSight product line includes: ClearSight Analyzer, ClearSight Analyzer 10/100 Full Duplex, ClearSight Analyzer Gigabit and ClearSight Analyzer 10 Gigabit. These network and application troubleshooting tools support the same breadth and depth of networking protocols as traditional analyzers, yet the intuitive depiction of the application conversations, along with the comprehensive flow analysis, goes far beyond the capabilities of historic analyzers. Using ClearSight's products, network and application professionals can see exactly what the user experienced when encountering network and application problems, enabling personnel across disciplines to quickly pinpoint problems in real-time, leading to more effective use of resources and high availability of business critical applications.

Network Computing revealed its Well-Connected Award winners in a special ceremony prior to the 2004 NetWorld+Interop event in Las Vegas. All finalists and winners will be highlighted in the May 13 issue of the publication.
