Imperva Ranked Number 334 Fastest Growing Company in North America on
Deloitte’s 2014 Technology Fast 500^TM

Attributes 250 Percent Revenue Growth to Demand for Best-in-Class Data Center Security Solutions

REDWOOD SHORES, Calif., November 13, 2014 – Imperva Inc. (NYSE: IMPV), pioneering the third pillar of enterprise security with a new layer of protection designed specifically for physical and virtual data centers, today announced it ranked 334 on Deloitte’s Technology Fast 500^TM, a ranking of the 500 fastest growing technology, media, telecommunications, life sciences and clean technology companies in North America.

“Cyber attacks keep growing in size, frequency and complexity, and as we hear in the news every day, no business is immune from threat. CIOs in global 2000 companies now understand the likelihood of a breach, and that they can no longer play to win, but are instead forced to play not to lose,” said Anthony Bettencourt, President and Chief Executive Officer of Imperva. “Protecting corporate data helps the CIO mitigate risk. We believe our solutions are truly the best line of defense between an organization’s data assets, and bad actors, providing protection from attack, theft and fraud. The company’s strong showing on Deloitte’s Technology Fast 500 for the third year running is a testament to our commitment to innovation and ability to scale both our offerings and our business to meet the growing global demand for best-in-breed security and compliance solutions.”  

“The companies ranked on the 2014 Deloitte Technology Fast 500 continue to set the bar for their industry higher each year,” said Eric Openshaw, vice chairman, Deloitte LLP and U.S. technology, media and telecommunications leader. “There are so many exciting products and smart thought leaders driving this list. We congratulate the Fast 500 companies and look forward to seeing them continue their momentum into 2015.”

“For 20 years, the Deloitte Fast 500 rankings have honored the innovation that is part of these companies’ DNA,” added Jim Atwell, national managing partner of the emerging growth company practice, Deloitte & Touche LLP. “We’re glad to be serving these high-growth companies, and helping the technology sector recognize the great strides and transformation these companies are making in their respective areas.”

Imperva previously ranked 352 as a Technology Fast 500^TM award winner for 2013.
