CUPERTINO, Calif. -- Proofpoint, Inc., the leader in large-enterprise messaging security solutions, today announced that it has closed another record quarter. Proofpoint’s Q3 2006 revenues increased by 77% year-over-year from Q3 2005, making it the largest revenue quarter in the company’s history.

In the third quarter of 2006, Proofpoint continued to see a dramatic increase in demand for the company’s inbound anti-spam and anti-virus modules as well as its outbound data privacy, intellectual property protection and regulatory compliance modules.

Proofpoint added numerous large-enterprise customers during the quarter including Baptist Health South Florida, Cape Cod Healthcare, Copart, Facey Medical Foundation, Hallmark Health, Harvard Business School Publishing, infoUSA, KidsPeace, La-Z-Boy Incorporated, Los Alamos National Bank, National Health Group Pte Ltd (Singapore), National Life Group, Occidental College, San Diego State University Research Foundation, The Blackstone Group and Varian Semiconductor. Proofpoint’s extremely high level of customer satisfaction helped the company once again exceed its customer subscription renewal targets.

“Proofpoint’s comprehensive approach to messaging security—offering protection for both inbound and outbound email on one easy-to-use, cost-effective platform—continues to be extremely well received in today’s high-risk email environment,” said Gary Steele, CEO of Proofpoint. “Large enterprises, universities and government organizations alike want to eliminate the threat of spam and viruses while also reducing the legal, financial and regulatory risks associated with outbound email. Proofpoint offers the industry’s most advanced and effective solution to both of these problems.”
