Imperva Raises $17M in Series C Financing

Greylock Partners, Accel Partners, US Venture Partners, and Venrock Associates Invest in Data Security Appliance Vendor

FOSTER CITY, Calif., May 17, 2006 – Imperva™, the leader in data security for the data center, today announced that it has raised $17 million in a Series C round of venture capital financing. The funds will be used to expand direct and channel sales infrastructure on a global basis to capitalize on the rapidly expanding market opportunity for its data security, data assurance, and regulatory compliance products.

The round was led by Greylock Partners, and supported by previous investors Accel Partners, US Venture Partners, and Venrock Associates. The company has raised a total of $33.7 million in three rounds of financing for the SecureSphere product line, which addresses the issues of insider abuse and criminal activity targeting corporate databases and sensitive e-commerce applications. Imperva founder and CEO Shlomo Kramer was a founder of firewall giant Check Point Software Technologies.
