Fenwick & West was founded in 1972 in the heart of Silicon Valley—before “Silicon Valley” existed—by four visionary lawyers who left a top-tier New York law firm to pursue their shared belief that technology would revolutionize the business world and to pioneer the legal work for those technological innovations. In order to be most effective, they decided they needed to move to a location close to primary research and technology development. These four attorneys opened their first office in downtown Palo Alto, and Fenwick became one of the first technology law firms in the world.  MORE >

Fenwick & West Represents Imperva in Three Strategic Acquisitions

February 10, 2014

Fenwick & West is pleased to announce its representation of Imperva, Inc. (NYSE: IMPV), a leading provider of business security solutions focused on providing visibility and control over high-value data across critical systems within the data center, in three strategic acquisitions, further strengthening Imperva’s data center security strategy across the cloud.

Imperva acquired Israel-based SkyFence Networks, Ltd., a provider of real time visibility and control over corporate use of SaaS applications, which enforces security policy, protects sensitive data from external and inside threats, and ensures compliance with standards. Imperva acquired from the SkyFence Shareholders all of the outstanding capital stock of SkyFence in exchange for approximately $60 million in Imperva Common Stock and cash.

Imperva also agreed to acquire the remaining stake in Incapsula, Inc. that it did not already own, in order to accelerate its ability to deliver security for external facing production applications like online banking, online gaming and retail applications. Through an application-aware global Cloud Delivery Network (CDN) platform, Incapsula provides websites and web applications with best-of-breed security, DDoS protection, load balancing, and failover solutions, available as standalone services or as an integrated solution. Imperva expects the acquisition of Incapsula to close in the first quarter of 2014.

Additionally, Imperva also announced its new SecureSphere Web Application Firewall version for Amazon Web Services (AWS).

The acquisition of SkyFence, the agreement to acquire the remainder of Incapsula, and the public launch of SecureSphere Web Application Firewall for Amazon Web Services forms the core of Imperva’s recently announced comprehensive cloud strategy, further extending its data center security suite of offerings across the cloud with solutions that are unmatched in the industry.

Imperva also acquired assets from Tomium Software, LLC, which included real-time mainframe security auditing agents. Tomium Software monitoring agents stream real-time audit data to the Imperva SecureSphere platform, a centralized security management and reporting framework. The acquisition from Tomium will allow Imperva to accelerate and expand its mainframe data security solutions.

The Fenwick transaction team for the SkyFence acquisition included corporate attorneys David Bell, Amit Khanna and Evan Johnson.

The Fenwick transaction team for the Incapsula acquisition included corporate attorneys David Bell and Daniel Parames; and technology transactions attorney Spencer Glende.
