PRESS RELEASE

REDWOOD SHORES, Calif., Jan. 24, 2011 -- Imperva, the leader in data security, today announced the new PartnerSphere Technology Alliance, a technology ecosystem dedicated to data security and compliance. The PartnerSphere Technology Alliance offers organizations an end-to-end blueprint for data security, providing best-of-breed products that complement and extend Imperva SecureSphere Web Application, Database, and File Security Solutions.

"Our partner ecosystem is growing rapidly as the demand for a data security strategy increases," said Imperva VP of Business Development, Farzad Tari. "Our program recognizes the reality of today's IT security landscape by partnering with leading technology providers in a formal, cohesive fashion, creating a partner ecosystem to protect structured and unstructured data."

Imperva has partnered with industry-leading vendors in several categories including Vulnerability Assessment, SIEM, Business Software, Platform, Application Delivery, Identity Management, and Masking and Encryption. Together, Imperva and its technology partners offer fully complete solutions that address organizations' top data security challenges.

With the creation of the PartnerSphere Technology Alliance, Imperva also announces two new partnerships with WhiteHat Security and Net Optics:

Imperva WAF Quick Start Program includes WhiteHat Sentinel Website Vulnerability Management:

Imperva and WhiteHat Security have joined forces to offer a closed-loop process to identify and mitigate website vulnerabilities. Beginning today, Imperva's Web Application Firewall Quick Start Program, a packaged professional services engagement for initial product installation and configuration, will include one WhiteHat Sentinel vulnerability assessment. As part of the Quick Start Program, WhiteHat Sentinel will conduct a website vulnerability assessment. All results are verified for accuracy, eliminating false positives. Then an Imperva professional services consultant will import the verified WhiteHat assessment results into the SecureSphere Web Application Firewalls to instantly remediate discovered vulnerabilities.

The Quick Start Program now allows customers to leverage the full benefits of the Imperva SecureSphere and WhiteHat Sentinel integration. Customers can immediately mitigate Web application vulnerabilities, eliminating the window of exposure inherent with manual remediation. Virtual patching also allows customers to design and implement code fixes on their schedule, avoiding emergency fix and test cycles.

"The combined Imperva and WhiteHat solution effectively detects vulnerabilities and protects against website attacks. This integration provides a complete and automated way for organizations to simplify the management of the Web application security lifecycle," said Bill Pennington, Chief Strategy Officer, WhiteHat Security. "WhiteHat Sentinel delivers ongoing accurate website vulnerability data that enables Imperva SecureSphere customers to deploy virtual patching with confidence. Organizations can design and implement application code fixes on their schedule, without rushing to fix and test patches, eliminating disruption in their development cycle. This allows businesses the freedom to decide how and when to mitigate web application security vulnerabilities in production."
