Press Release: PGP Corporation Continues as Lead Vendor

Latest Study by TheInfoPro Confirms More Customers Considering Deploying
PGP Solutions than Any Other Data Encryption Solution

Survey of Fortune 1000 companies demonstrates PGP Corporation's continued leadership in data encryption and secure email messaging

Palo Alto, CA/09 March, 2006 - PGP Corporation, a global leader in enterprise data security and encryption solutions, today announced that the latest Information Security Study conducted by TheInfoPro (TIP), an independent research network and leading supplier of market intelligence for the information technology industry, rated PGP Corporation once again as the lead vendor in use for both email and data encryption software. PGP Corporation was also ranked as a Tier 1 vendor in the Network Security & Security Infrastructure categories along with Cisco Systems, IBM, Symantec, and other industry leaders.

TheInfoPro surveyed information security professionals from North American Fortune® 1000 and mid-sized enterprises, major government agencies, and leading academic institutions about implementation and spending plans, vendors, and products in 40 information security technology categories, including email and data encryption software to provide infrastructure security. The Wave 6 Winter 2005/2006 study indicates that almost 75 percent of participants consider internal vulnerabilities of greater or equal concern to external threats. Part of the shift toward internal vulnerabilities is due to increased focus on the dangers to data at rest rather than data in transit. End users cited represent some of the world's most popular brands, such as Cisco Systems, Citigroup, FedEx, IBM, JPMorgan, Microsoft, Oracle, Pfizer, Sprint, and Visa.

"Data encryption has taken a large step upward on the TIP Technology Heat Index™ in Wave 6, moving up to rank 11th among large enterprises from 29th in the previous Wave and to rank 6th among mid-sized enterprises," said Henry D. Nissenbaum, managing director for information security research at TheInfoPro. "The technologies at the top of this index are the ones receiving the highest priorities for 2006. Fifty-five percent of large enterprise security managers project higher spending on data protection in 2006, and PGP Corporation leads the other "in-use" data encryption vendors by a margin of almost 20 percent. This study showed that more customers are considering deploying PGP solutions than any other competing data encryption or secure email messaging solution. We also found that security managers felt PGP encryption was easy to use and provided comprehensive protection for their confidential and mission-critical data."

"The results of the latest third-party TheInfoPro survey and strong customer adoption clearly substantiate the increasing demand for PGP encryption solutions," said Andrew Krcik, vice president of marketing for PGP Corporation. "The unified PGP Universal™ Encryption Platform provides the scalability, simplicity, and inexpensive deployment customers need to address immediate risks and then expand into a more comprehensive solution over time. The new TIP study demonstrates PGP Corporation's continued and growing leadership in data encryption and secure email messaging."
