ATLANTA -- Witness Systems (NASDAQ: WITS), a leading global provider of workforce optimization software and services, today announced that new research from The PELORUS Group, Tern Systems, and DMG Consulting reveals the company's market leadership in several categories.

The PELORUS Group

According to the "2006 World Contact Center Recording Systems Market" report published by The PELORUS Group (www.pelorus-group.com), an independent market research and consultancy company for the financial services and telecommunications markets, Witness Systems holds a leading 33.6 percent in the broadly defined recording (both combined and selective) software and services global market. Additionally, the report shows Witness Systems leading in two other categories - the company boasts a 43.3 percent share in selective recording and is the clear leader in recording software and services in North America with 29.9 percent.

"In a largely technology-driven market, Witness Systems is perhaps the best at conducting market research and listening to customer needs," said Dick Bucci, associate consultant, The PELORUS Group. "The company is well ahead of the curve in recognizing that recording solutions have applications well beyond contact centers, a direct result of customer feedback. Its leadership and market share numbers represent and reinforce that continued commitment to customer service and success."

Tern Systems

New research from Tern Systems, a highly regarded market research firm specializing in the call automation area, indicates that Witness Systems leads the quality monitoring systems installed base category with 40.9 percent. The report entitled "2006 Voice/Data Recording Market Report" also positions the company as a leader in quality monitoring shipments with 39.6 percent market share. Witness Systems received further recognition by leading the shipments for quality monitoring software with 44.8 percent, as well as the installed customer base for quality monitoring software with 46.1 percent.

"The call recording vendors are offering integrated suites that tie together capabilities from single component technologies, such as call recording and quality monitoring," said Walt Tetschner, founder and president, Tern Systems. "Witness Systems is leading the pack with its Impact 360[TM] solution and that became clear in the numbers for this year's report."
