WESTFORD, Mass., Feb. 24 /PRNewswire-FirstCall/ -- NetScout Systems, Inc. (Nasdaq: NTCT), a leading provider of network performance management solutions, today announced several new premier U.S. companies that are deploying the nGenius(R) Performance Management System to assure the performance and availability of their mission-critical networks and applications. Among these new customers are:

    -- Coors Brewing Company, the third largest brewer in the U.S. and one
       of the top 10 brewers in the world;
    -- Borders Group, Inc., a leading book, music and movie retailer, with
       over 1,200 stores and 32,000 employees world-wide; and

Companies like these are using nGenius to proactively assure their network and application infrastructures perform optimally in support of their unique business needs. nGenius helps enterprises assure success for their individual business priorities such as:

    -- Gaining proactive control over performance and costs, network-wide.
       nGenius assures visibility into the performance of all standard and
       proprietary applications being delivered -- from the Web, to the front
       office, to the back office;
    -- Proactively mitigating performance faults on the network before they
       compromise internal or customer-facing services.  For example, assuring
       the performance of credit card transactions with round-the-clock,
       continuous monitoring;
    -- Monitoring, understanding and assuring the impact and success of new
       network services such as Voice-over-IP; and
    -- Lowering network costs by using the real-time information gained from
       nGenius as a basis for taking corrective action, like reconfiguring
       traffic flows to make better use of existing network assets,
       improvement in application designs, and putting an end to network
       misuse.

"In this tight economy, customers can use nGenius to leverage their existing resources into full support of their most important business initiatives," said Jim Frey, vice president of marketing for NetScout Systems, Inc.
