Voltage Security´s Identity-Based Encryption a Part of Microsoft Exchange Hosted Encryption Service

Voltage Security, Inc. (www.voltage.com), a global leader in enterprise privacy management, today announced that Voltage´s Identity-Based Encryption offering is a key component of Microsoft´s Exchange Hosted Encryption, one of the four distinct managed services offerings that make up Microsoft Exchange Hosted Services. These services help minimize upfront capital investment, free up IT resources, and empower companies to concentrate on areas most critical to their business.

Exchange Hosted Encryption, which includes Voltage´s IBE, preserves e-mail confidentiality by helping organizations send confidential information to customers or partners. In addition, Exchange Hosted Encryption helps organizations meet corporate and regulatory compliance by encrypting messages based on email policy.

Exchange Hosted Encryption enables users to send and receive encrypted e-mail directly from their desktops. Using a simple process, users can encrypt and deliver any business communication without complex hardware and software to purchase, configure, and maintain. Likewise, recipients of encrypted messages receive messages using their existing email client and can view messages without the need of any additional hardware or software.

"Email encryption made available as a service is the most cost-effective way to protect sensitive information flowing to and from the enterprise," said Sathvik Krishnamurthy, president and CEO of Voltage Security. "Voltage IBE is the only encryption solution that provides the scalability required in a managed service environment. We´re proud to be working with Microsoft to be able to bring our solutions to the broad global market as part of Microsoft´s Exchange Hosted Service offering."

"We are working with Voltage to provide customers with a choice in how they deploy their security solutions," said Eron Kelly, Director of Exchange Hosted Services at Microsoft Corp. "Exchange Hosted Encryption is a hosted solution that helps customers protect the privacy of their email communications with their trading partners and customers regardless of the recipients´ email solution."


About Microsoft Exchange Hosted Encryption

When a user sends an e-mail message, it travels to the Microsoft global network through a Transport Layer Security (TLS)-encrypted tunnel, and is automatically encrypted at the gateway according to rules created and managed within the Microsoft Exchange Hosted Filtering module. The Microsoft encryption process is entirely transparent to the sender, who does not need to do anything other than write and send the message as usual.

Upon receiving a Microsoft Exchange encrypted message, the recipient completes a two-step authentication process through e-mail answerback to verify the recipient´s identity. After completing the authentication process, the recipient decrypts and views the message using the Voltage Zero Download Messenger(TM) (ZDM). The Voltage ZDM is a clientless, browser-based approach that enables a recipient to have confidence decrypting and reading a message and its attachments and then replying. Furthermore, the encrypted message remains in the recipient´s e-mail inbox for access at any time.

About Voltage IBE

Voltage IBE is a public key cryptography system that uses common identities (such as an email address or screen name) as public keys, eliminating the need for certificates, Certificate Revocation Lists (CRL) and other costly infrastructure. Voltage IBE results in a solution that is easy to implement and easy to manage, without the overhead and cost inherent in traditional security solutions. Voltage IBE is ideal for use with financial services customers and medical patients who expect communication to be kept private and secure and also want ease-of-use and low-cost. Voltage IBE solutions are:

-- Easy to implement and easy to manage -- eliminates the overhead and costs inherent in traditional security solutions such as PKI

-- Highly scalable -- no storage of keys or messages, and no need to contact online servers; allows the solution to scale dramatically without the need for additional infrastructure

-- Easy to use -- no need for end users to worry about keys, certificates or multiple inboxes
