Sigaba Extends Email Security To Wireless LANs, Blackberry
July 12, 2002

Sigaba, Inc. this week unveiled extensions to its secure email platform that address users of wireless LANs and Blackberry handheld devices.

Sigaba makes a platform that supports encryption and decryption of email messages without much of the complexity that encryption typically implies. The company's technology allows secure messaging even between users with ad hoc or transitory relationships with one another. In that fashion, it allows companies such as financial services and health care firms to comply with privacy regulations in those industries, says Tanya Candia, senior vice president of marketing for Sigaba, based in San Mateo, Calif.

When a user constructs an email he wants to send securely, he authenticates himself to the Sigaba server. The server can be integrated with existing enterprise authentication systems, including LDAP directories, tokens, smart cards and public key encryption systems. The Sigaba server generates a key to encrypt and decrypt the message, but the key stays at the server while the message is sent to the recipient.

When the message is received, a Sigaba plug-in on the client machine opens up an authentication screen. Once the recipient is authenticated, the key is retrieved and the message opened. Message senders can maintain control over such qualities as how long the key is valid, perhaps expiring after two, four or eight hours.

Now Sigaba is extending that same base technology to Blackberry devices and wireless LANs. In both instances, Sigaba has a gateway that sits next to the wireless transmitter or Blackberry Enterprise Server. The gateway encrypts messages before they are sent over the untrusted network.

In the case of the Blackberry, another Sigaba gateway is required to decrypt the message before it is sent to the remote Blackberry server, which applies its own Triple DES encryption before it is send to the end Blackberry device. For wireless LANs, the receiving PC uses the Sigaba plug-in to authenticate and decrypt the message.

"We spent a long time building the base architecture for this product," says Robert Cook, chairman and CEO of Sigaba. "Now you're seeing new applications built on top of that architecture. More will roll out quickly," he says, including new management tools and products to secure Web services.

Pricing for each Sigaba product starts at $50,000 to support 100 users. It costs about $20,000 to add another service, such as adding the Blackberry capability to an existing wireless LAN implementation.
