NETSCOUT Wins Award for Best-in-Class Customer Satisfaction; Omega Management Group Honors NetScout with NorthFace ScoreBoard Award For Excellence in Customer Support and Sales Process

April 4, 2006

WESTFORD, Mass.--(BUSINESS WIRE)--April 4, 2006--NetScout Systems, Inc. (NASDAQ: NTCT), a leading provider of application and network performance management solutions, today announced that it has received a second consecutive NorthFace ScoreBoard Award for excellence in customer satisfaction from the Omega Management Group. NetScout earned the award based on best-in-class customer satisfaction ratings from its user base throughout 2005.

Omega, recognized experts in customer loyalty management programs, gives NorthFace ScoreBoard awards to companies whose customers give satisfaction ratings of 4.0 or higher out of a possible 5.0 in surveys on key areas of customer service. Omega's market research indicates that achieving a 4.0 rating or above over an extended period of time is clear evidence of customer loyalty. Consistent satisfaction at this level essentially locks-in profitable long-term customer relationships and significantly raises the bar for competitors.

NetScout achieved best-in-class ratings in the customer support category based on its technical support team's responsiveness, communications, expertise, professional attitude, and overall relationship with customers. NetScout's sales team was similarly recognized for its excellence in the sales process category this year, based on its responsiveness and availability, expertise, setting appropriate product expectations, and overall relationships with customers.

During Omega's semi-annual surveys of NetScout's user base, customers can offer suggestions about what they'd like NetScout to change in their business relationship, product features, training and documentation. NetScout also leverages the survey to review relationships with specific customers, and customers send their feedback on company performance directly to NetScout executives.

"To win this award NetScout not only demonstrated exemplary service through its own customers' ratings, but also a firm commitment to exceeding customer expectations," said John Alexander Maraganis, president & CEO of Omega. "This award, especially for the second consecutive year, is clear proof that NetScout is executing well on its commitment to superior customer satisfaction."

"We thank our customers for this honor and for recognizing all of our employees' efforts to better serve their needs," said June Nugent, director of Knowledge Resources who leads the Customer Satisfaction program for NetScout. "The Omega survey serves a vital purpose for NetScout: to consistently measure our ongoing relationship with the users of our performance management solutions. We use the results to focus on what we need to address and improve for our customers every step of the way."

NetScout will receive their award at Omega's annual Symposium for Customer Operations & Relationship Exposition (SCORE) Conference running from June 12-15 in Boston.
