PRESS RELEASE

Redwood Shores, CA – March 8, 2011 – Imperva, the leader in data security, today announced the availability of SecureSphere 8.5, which extends protection from insider threat with enhanced SecureSphere Agent Technology for file and database activity throughout the IT infrastructure. SecureSphere 8.5 extends Imperva’s award-winning data security solution, combining network monitoring and local monitoring via agents to provide support for data platforms including Windows file servers and mainframe databases as well as optimized local agent performance and management experience.

“Network-based file activity monitoring alone cannot peer into local console-based access and may not be cost-effective for remote locations, creating blind spots for many enterprises,” explained Neil MacDonald VP and Gartner Fellow. “Comprehensive file monitoring must support both agent and network-based approaches for complete coverage.”

SecureSphere 8.5 adds Windows File Server agents as a deployment option. Agents can be used in conjunction with SecureSphere File Security appliances to optimize deployments based on network topology and business needs. Key capabilities include:

Enables privileged user monitoring and separation of duties through visibility into administrative and all other local activity;

Provides clear visibility into user identities and access activity in encrypted networks;

Supports efficient auditing of distributed file servers in multiple data centers or branch offices.

In addition, SecureSphere 8.5 will include new agent-based monitoring and auditing for DB2 z/OS mainframe databases. The mainframe agent delivers a comprehensive and efficient solution for auditing database activities and addressing regulatory requirements related to critical mainframe systems. Key capabilities include:

Complete visibility into critical operations, including: SELECTS, DML and DDL, privileged activities and DB2 utilities;

Offloads processing to zIIP processors to minimize impact on total cost of mainframe computing;

Generates real-time alerts on policy violations and security events;

Fully integrated into the SecureSphere suite for cross-platform audit management.

Finally, SecureSphere 8.5 optimizes agent-based monitoring and auditing for open systems databases. The SecureSphere database agents are designed to minimize monitoring overhead and are deployed and upgraded without the need to restart target databases. SecureSphere architecture scales to support large number of agents delivering thousands of transactions per second of audited data. Agent-based monitoring can cover local traffic or all traffic and can be combined with network based monitoring for highly optimized database security deployment.

“With this release, Imperva expands the industry’s most comprehensive data security suite,” said Imperva CTO Amichai Shulman. “With our agent technology, Imperva gives enterprises the most complete solution to protect data as it moves from database to files and applications.”

SecureSphere 8.5 is available immediately for customer deployments. Certain features are scheduled for release in Q2 2011; please contact Imperva Sales for further information. About Imperva
