Imperva, a California-based information security company, announced on Thursday that it is acquiring Israeli cloud-based security firms Skyfence and Incapsula. Imperva founder and CEO Shlomo Kramer is a lead investor in cloud security gateway startup Skyfence. Imperva has an existing interest in cloud-based web application security company Incapsula; it has an agreement in principle to acquire the remaining shares.

Imperva has also announced the acquisition of technology from U.S.-based Tomium Software.

The purchase price for Skyfence was $60 million, but the price tag on the remaining shares of Incapsula was not announced. The news of the acquisition of the two companies coincided with Imperva’s release of its SecureSphere Web application firewall version for Amazon’s cloud-based Web services. Imperva’s VP for technology, Amichai Shulman, who was a cofounder of the company, told TheMarker the acquisitions were designed to create an integrated structure supporting Imperva’s involvement in the cloud computing field. The plan is to have to Skyfence and Incapsula continue to operate independently, while Incapsula is expected to bring on about 30 additional employees.

Incapsula, which was founded in 2009 by Gur Shatz and Marc Gaffan, has developed a cloud-based application delivery platform that acts as a Web application firewall. The initial concept for the company was developed by Shatz and by Kramer, who was actually the one to get Shatz – Imperva’s product development director at the time—together with Gaffan.

Incapsula, which has a staff of about 50 in Rehovot, maintains servers at hosting suppliers around the world and provides website hosting on servers it leases, providing services such as boosting download speeds and information security technology at prices that beat out some of its competitors.

Skyfence, founded in 2012 by Ofer Hendler and Michael Kantarovich, develops products to ensure the security and compliance of cloud application and data. The company’s lead investors are Kramer and Mickey Boodaei, the founder and CEO of Trusteer, which was acquired by IBM last August for $650 million. Skyfence has a workforce of about 15 people in Ramat Gan.
