CIPHERTRUST ® AND VOLTAGE SECURITY JOIN FORCES TO PROVIDE POLICY-DRIVEN E-MAIL ENCRYPTION TO ENTERPRISES

CipherTrust Offers Voltage IBE Server as Key Component of IronMail Privacy Architecture

Atlanta, GA., July 20, 2004 -- CipherTrust, Inc., the leader in messaging security, and Voltage Security Inc., a leading provider of secure business communication solutions, today announced a partnership to offer the Voltage IBE Server as part of CipherTrust's IronMail Privacy Architecture (IPA).

CipherTrust 's IPA is a policy-driven capability to provide regulatory compliant messaging and comprehensive e-mail privacy capabilities with flexible delivery options and low total cost of ownership. As a key component of IPA, the Voltage IBE Server provides secure messaging without requiring certificates or the overhead of traditional public key encryption (PKI).

"Secure e-mail is merging into broader e-mail content security.This makes perfect sense: the decision to secure an e-mail is a matter of policy, just as are other decisions about message handling," says Jonathan Penn , analyst, Forrester Research*.

CipherTrust 's IPA, when using the Voltage IBE Server, provides multiple deployment and authentication options for two-way communication: non-technical users such as consumers, doctors, and employees can send secure messages with the click of a button inside their preferred e-mail client. Al ternatively, Voltage's Zero Download Messenger enables users to decrypt and encrypt without the need to download any software. In addition, the Voltage IBE Server enables messages to be encrypted/decrypted at the server level based on company-wide policies, providing fully compliant secure messaging.

"Our enterprise customers are increasingly looking for an integrated secure messaging platform to sit at the edge of their corporate networks," said Sathvik Krishnamurthy, CEO of Voltage. "By teaming with CipherTrust , we are combining its proven expertise in the messaging security arena with our award-winning messaging encryption platform. With CipherTrust and Voltage, customers can easily deploy and scale a secure messaging solution to serve employees, customers, business partners and others beyond the firewall."

"CipherTrust's customers trust IronMail to protect the lifeblood of their company - messaging infrastructure, defending against the entire range of messaging security threats," said Steve Raber, CipherTrust's president and CEO. "With this partnership, CipherTrust has made it extremely easy for customers to utilize Voltage's innovative identity-based encryption to achieve the highest levels of message protection."

IPA provides IronMail customers with a complete range of encryption capabilities to ensure e-mail messages are not tampered with or exposed during transit, including support for the Transport Layer Security (TLS) protocol, S/MIME and PGP standards, a secure web-based delivery function and, now, the Voltage IBE Server. This broad support of multiple encryption methods simplifies the deployment and adoption of encrypted e-mail for CipherTrust 's customers.

CipherTrust is the first messaging security company to provide an integrated and complete e-mail gateway privacy solution, allowing customers to select the sophistication and type of encryption required, all driven by IronMail's best-of-breed policy enforcement capabilities. Based upon policy triggers, IPA will route message traffic to the Voltage IBE Server, protecting an organization's message traffic with the most effective means based on real-time decisions about message characteristics including content, sender and recipient.
