Symantec Enterprise Vault Positioned in Leaders Quadrant in Analyst Firm's Magic Quadrant for E-mail Archiving

CUPERTINO, Calif. – May 24, 2006 – Symantec Corp. (NASDAQ: SYMC) today announced that it has been positioned in the Leaders Quadrant of Gartner's Magic Quadrant for E-mail Active-Archiving, 2006. A key component of Symantec's Enterprise Messaging Management solution portfolio, Symantec Enterprise Vault(TM) e-mail and content archiving software enables companies and government agencies to reduce storage costs, protect critical records, improve employee productivity and achieve compliance with industry and government regulations requiring the retention and supervision of e-mails, instant messages and other forms of electronic communications and collaboration.

According to the Gartner report, published May 12, 2006, vendors included in the Leaders Quadrant have the highest combined measures of an ability to execute and a completeness of vision. They have the most comprehensive and most scalable products, and a proven track record of financial performance and established market presence. In terms of vision, they are perceived as thought leaders, with well-articulated plans for ease of use, how to address scalability and product breadth. For vendors to have long-term success, they must plan to address the expanded market requirements for archive management, personal store migration, ease of use and deployment, and archive recovery. Leaders must not only deliver to current market requirements, which continue to change, but they need to be able to anticipate and begin to deliver on future requirements. A cornerstone for leaders is the ability to articulate how these requirements will be addressed as part of their vision for expanded archive management. The report also states that as a group, leaders can be expected to be considered as part of most new purchase proposals and have high success rates in winning new business.

"Symantec Enterprise Vault is the market-leading content archiving solution with more than 3,000 customer installations worldwide managing five million mailboxes," said Francis deSouza, vice president of Enterprise Messaging Management solutions, Symantec. "As the market for archiving has expanded to include other forms of content we have developed additional capabilities within Symantec Enterprise Vault to enable archiving of instant messages, Microsoft Windows and Network Appliance file systems and Microsoft SharePoint documents. In addition, we have continued to expand the notion of Enterprise Vault as an Intelligent Archiving platform by providing open APIs to allow customers and partners to expand and leverage the technology."
