Redwood City, CA. - June 5, 2006 -- Decru, a NetApp (NASDAQ: NTAP) company, today unveiled a new key management platform, the Decru® Lifetime Key Management™ 3.0 Appliance (LKM Appliance). The LKM Appliance extends Decru's proven capabilities for secure, automated, enterprise-class management of storage encryption keys and adds integration capabilities for third-party encryption products. Decru also announced today that Symantec Corp. (NASDAQ: SYMC) and Quantum Corp. (NYSE: DSS) have joined as charter members of the Decru OpenKey partner program, which provides a framework for development of standards-based multiparty encryption solutions.

Continuing disclosures of privacy breaches are driving requirements for enterprise-wide encryption and key management. The Decru Lifetime Key Management system, which has been shipping since mid-2003, is the industry's most mature and advanced storage key management system. Decru DataFort™ storage security appliances and LKM already support many of the world's largest and most sophisticated storage security deployments, including financial services and Global 1000 customers. The LKM Appliance extends this leadership position by providing centralized key management for heterogeneous third-party software and hardware encryption devices.

"Enterprises increasingly realize the need to encrypt sensitive data, but they are justifiably concerned with the prospect of running multiple proprietary key management systems over the coming years," said Jon Oltsik, senior analyst at Enterprise Strategy Group. "By providing a broad line of storage security appliances, and opening up its key management platform to third parties, Decru is providing a centralized key management solution and addressing an impending pain point for enterprises. Decru's market successes, coupled with support by major vendors such as Symantec and Quantum, puts it in a good position to solve this problem."

Unified Platform for Enterprise-Wide Key Management
The Decru Lifetime Key Management system uses Decru DataFort secure hardware to protect and manage encryption keys throughout their entire lifecycle, including key generation, replication, archiving, recovery, sharing, and deletion. The Decru Storage Encryption Processor (SEP) has received FIPS 140-2 Level 3 certification, and is used today in highly sensitive military and Global 1000 enterprise environments. The new LKM Appliance incorporates Decru SEP into a dedicated key management appliance, enabling a broader range of functionality for centralized management and policy enforcement.

The LKM Appliance provides a wide range of industry-leading benefits:

• Mature platform: The Decru key management platform has been proven in demanding real-world deployments, supporting large clusters of encryption devices across multiple distributed data centers.
• Scalability: Each appliance can securely store more than 10 million encryption keys, and an LKM fabric consisting of clustered appliances can scale to support over a thousand encryption devices.
• Secure management: The LKM Appliance is also designed for FIPS 140-2 Level 3 physical security. Administrative access is secured by two-factor authentication, role-based access controls, and smart card quorum requirements for sensitive operations.
• Automation: The LKM Appliance securely automates key management functions including key generation, replication, archiving, recovery, and sharing. The LKM Appliance and DataFort appliances automatically and securely propagate encryption keys to configured systems and utilize features such as key translation and trustee key sharing to enable secure information sharing across groups or companies. Decru CryptoShred™ secure deletion enables sophisticated lifecycle management of encryption keys, including policy-based key expiration.
• Heterogeneous support: The LKM Appliance provides centralized key management across all DataFort appliances, enabling enterprise-wide support for NAS, DAS, iSCSI, FC SAN, and tape storage environments. The LKM Appliance can also be deployed to support new and existing Decru DataFort appliances.
• Open and standards-based: The Decru OpenKey partner program and APIs enable unified support for heterogeneous encryption systems, simplifying the deployment of encryption across multiple environments.
• Secure key generation: Many encryption systems lack the ability to generate strong, random encryption keys, significantly reducing the overall level of security. Decru DataFort and the LKM Appliance use a hardware-based true random-number generator to create strong, high-entropy keys.

"Decru has more experience than any other company in deploying large, enterprise-wide storage encryption projects," said Suresh Vasudevan, senior vice president and general manager of Decru, a NetApp company. "By extending our key management platform into a secure appliance, and working closely to integrate with other leading vendors, Decru is providing its customers with unprecedented flexibility and functionality."

Decru Lifetime Key Management 2.5 software is available immediately. The Decru Lifetime Key Management Appliance is planned for availability in Q3 2006.
