Company revenue grows 43 percent year over year, Q4 2010 marks largest quarter ever

Redwood Shores, CA – January 31, 2011 – Imperva, the global leader in data security, announced today that it achieved record growth at the close of fiscal year 2010, experiencing a 43 percent increase in revenue over 2009 and marking Q4 2010 as the largest quarter on company record. In 2010, the company also expanded its executive team and board of directors as well as released new innovations in its SecureSphere Data Security Suite.

“Data breaches continue to inflict financial and reputation costs—especially WikiLeaks. In 2010, awareness grew dramatically around the need for database, application and file security. Not surprisingly, 2010 was a milestone year for Imperva and customer demand for our solutions has never been greater,” said Shlomo Kramer, Founder and CEO of Imperva. “In 2010 we were able to drive innovation in key areas including threat detection and file security as well as add experienced company-builders to our senior team and board. Imperva is poised for continued success in 2011.”

Highlights from 2010 include:

• Revenue growth of 43 percent over fiscal year 2009, and the addition of nearly 400 new global customers;
• Release of new products and services including SecureSphere File Activity Monitoring and automatic threat detection solution ThreatRadar, as well as the spinoff of Incapsula, a cloud-based website and web application security company;
• The company’s largest quarter on record, Q4 2010, with revenues from newly introduced products ThreatRadar and SecureSphere File Activity Monitoring doubling over the previous quarter;
• Increase in mid-market enterprise revenue of 104 percent over 2009 and well as 90 percent growth in MSSP revenue and 50 percent growth in professional services revenue year over year;
• Appointment of seasoned CFO, Terry Schmid, as well as the appointment of new General Counsel, Scott Darling, and the addition of Albert “Rocky” Pimentel as Audit Committee Chairman on Imperva’s Board of Directors.

“We’ll continue to focus on providing solutions and research that enable companies to do business while securing their data from evolving threats and attacks,” continued Kramer.
