Redwood Shores, CA – August 15, 2011 – Imperva, a pioneer and leader of a new category of data security solutions for high-value business data in the data center, today announced the addition of ServiceNow CEO Frank Slootman and industry veteran David Strohm to Imperva’s Board of Directors, effective August 9th.

“Frank and David bring valuable experience to our Board of Directors,” said Shlomo Kramer, CEO of Imperva, Inc. “Both have significant experience to help Imperva build and strengthen its position in the data security market. We welcome them in their new roles.”

Currently, Slootman is the CEO of ServiceNow, a leader in cloud-based IT infrastructure management which was recently named by Inc. 500 as one of the fastest-growing companies in the world. Prior to ServiceNow, as the CEO of Data Domain, Slootman blazed new trails creating a high-growth enterprise storage company that went public on NASDAQ in 2007. “Frank helped build DataDomain into one of the most successful and innovative enterprise infrastructure companies, shepherding the company through its 2007 IPO as well as its acquisition by EMC for $2.4 billion in 2009,” explained Kramer. “His guidance and experience will prove invaluable to Imperva.”

Previously, Slootman was senior vice president of product operations at Borland Software where he ran the company’s engineering and product management function. Additionally, Slootman spent seven years at Compuware as general manager of UNIFACE in Amsterdam and general manager of the EcoSystems division in Campbell, Calif. Slootman holds undergraduate and graduate degrees from the Netherlands School of Economics, Erasmus University Rotterdam in his native Holland.
