PGP Corporation Delivers Pre-Boot Authentication to PGP Whole Disk
Encryption for Mac OS X Users

Enterprise Security Management and Scalability From Single Console With PGP
Encryption Platform for both Mac and Windows Clients

Menlo Park, CA/9 June 2008 - PGP Corporation, a global leader in enterprise
data protection, announced today it has added pre-boot authentication to
the PGP Whole Disk Encryption for Mac OS X systems deployed in enterprise
environments. Already in critical use within pharmaceutical, government,
defense and education markets, Macs are making their way outside of
corporate marketing departments to mission critical areas of the
enterprise, where users and IS/IT departments must have strong data
security to protect intellectual property, customer and partner data and
corporate brand equity. The latest release to the PGP Encryption Platform,
PGP Whole Disk Encryption 9.9 adds pre-boot authentication to the proven
PGP Corporation data encryption technology for Intel-based Mac OS X systems
"Tiger" and "Leopard," providing protection for data on desktops, laptops,
and removable media. As Macs proliferate throughout the enterprise, IS/IT
departments now have an integrated, single management console for full disk
encryption with the same look and feel across Windows and OS X platforms.
PGP Corporation's desktop encryption solutions are the only products
available today for both Windows and Mac OS X that are FIPS 140-2 validated
for use by the U.S. government.

The increase in corporate Mac usage is evidenced by reports from a number
of leading analyst firms, including Forrester, which recently reported
enterprise adoption of Macs tripled last year to 4.2 percent (Forrester
Research, Enterprise Desktop And Web 2.0/SaaS Platform Trends 2007, March
2008). The introduction of Macs means the data that is created and shared
within the corporate environment poses a dilemma for security departments.
In a recent survey of 250 companies, research from the Yankee Group found
that 87 percent now have at least some Mac computers in their offices, up
from 48 percent two years ago.

"Use of Mac notebooks and desktops in the enterprise has dramatically
increased over the last few years, and we don't expect that growth to slow
anytime soon," said Jon Oltsik, Senior Analyst at Enterprise Strategy
Group. "The challenge for the enterprise has been straddling the desire for
the ease-of-use and array of applications that the Mac provides, with the
lack of data security solutions available. Standards-based, proven
encryption for Mac OS X is a long-awaited solution that addresses a growing
enterprise need."

In order to eliminate the risk of a data breach in the event of a lost or
stolen Mac, PGP Whole Disk Encryption 9.9 locks down the entire contents of
a laptop, desktop, external drive, or USB flash drive, including boot
sectors, system, and swap files. As a PGP Encryption Platform--enabled
application, PGP Whole Disk Encryption can be used with PGP Universal
Server to manage existing policies, users, keys, and configurations,
expediting deployment and policy enforcement.

"Mac adoption in mission critical areas of the enterprise is on the rise;
from product design, to engineering, to legal, securing intellectual
property is crucial," said Phillip Dunkelberger, President and CEO of PGP
Corporation. "As we have seen with our email and file products developed
for the Mac platform, corporate environments need solutions that easily
integrate with existing infrastructure and security standards. With PGP
Whole Disk Encryption, companies and government agencies alike can leverage
the PGP Encryption Platform to enforce policy and manage cost-effectively
Mac and Windows deployments."

Pricing and Availability

PGP Whole Disk Encryption 9.9 for the Mac is currently scheduled to ship in
July and can be purchased through the PGP global network of resellers. For
