PGP Corporation Partners With ChosenSecurity to Deliver RootSigning Services

Market Wire, April, 2007

ChosenSecurity, Inc., a leading specialist in identity verification and security services, today announced a partnership with PGP Corporation, a global leader in enterprise data security and encryption solutions, to integrate ChosenSecurity's RootSigning Services with the PGP® Encryption Platform. The integration enables customers to digitally sign encrypted email and data based on trusted Certificate Authority (CA).

In today's security-conscious and highly regulated business environment, enterprises increasingly look to digital signatures to ensure the integrity of business correspondence, verify a sender's authenticity, and increase trust. This partnership allows customers of the PGP® Encryption Platform to send digitally signed email based on a globally trusted root CA without needing a separate public key infrastructure (PKI). Email clients that natively support S/MIME, such as Microsoft Outlook and Outlook Express, will authenticate the signatures without requiring installation of additional client software.

PGP Corporation delivers the broadest set of integrated encryption applications to secure confidential customer and corporate information. Built on the PGP Encryption Platform, PGP® solutions protect laptop hard disks, USB devices, gateway and desktop email, network-stored files, instant messaging, and FTP and data transfers from a single policy and key management console that leverages a unified architecture. PGP® products are used by more than 80,000 organizations to help achieve regulatory and audit compliance and to safeguard data, brands, and reputations.

ChosenSecurity's RootSigning Service enables companies to retain full control of their Certificate Authority (CA) for issuing certificates for gateways and users (x.509), while at the same time receiving the security, trust and recognition that results from the connection with a trustworthy root certificate from TC TrustCenter, a wholly owned subsidiary of ChosenSecurity. With RootSigning, you easily achieve trusted status for your certificates worldwide and ensure their acceptance by 99% of all browsers. By leveraging ChosenSecurity's leading technology, expertise and established certificate practice statement, companies not only reduce costs, implement more quickly and enforce security, but they also win the trust of customers, partners and suppliers in their electronic communication.

"Customers often ask for the ability to incorporate root-signed certificates directly into the PGP Encryption Platform, so we are pleased to work with ChosenSecurity to offer this solution," said Rajiv Dholakia, Vice President, Strategy and Solutions, PGP Corporation. "Support for standards is a founding principle for PGP Corporation, and we have long supported both the OpenPGP and S/MIME v3 standards. While ChosenSecurity's flexibility and understanding of our requirements make it a trouble-free partnership, its globally accepted CA and commitment to enhancing the value of our S/MIME support truly set the company apart."

"We are very pleased to work with PGP Corporation and to provide RootSigning services as a means of support for PGP email and data encryption solutions," said Dean Coclin, Vice President of Business Development, ChosenSecurity. "The trusted status of ChosenSecurity's CA certificates is based on globally recognized and proven certification policies. With RootSigning, you assume these policies, and thereby lay the foundation for a universally recognized and trusted corporate CA at the same time, which is a significant benefit to any organization. We are excited about this new opportunity to support PGP Corporation in this manner."
