Encryption, compliance, management on tap from messaging security vendors

A number of messaging security vendors took advantage of last week’s RSA Conference 2006 in San Jose to announce new products and upgrades.

Among them, e-mail security service provider Postini announced plans to expand its encryption offerings. Building off Postini’s announcement last December with Zix Corp. to offer Zix’s policy-based encryption for inbound and outbound messages as part of its hosted service, Postini will add a number of different encryption technologies under the Postini Encryption Manager umbrella to create a federated encryption service over the course of the year, says Andrew Lochart, senior director of marketing.

The company wants to offer a variety of different encryption technologies since there is no market leader in the area and the products don’t interoperate with each other, Lochart says. Postini will hold the decryption key on behalf of customers and decrypt incoming messages that are secured in any of the formats the company plans to support so they can be scanned for spam, viruses, and other malware, he says.

Then Postini will encrypt messages again in any format the customer wants for the final leg from Postini’s service centers to a customer’s site. This way, Postini customers only need to use one form of encryption, regardless of what form the message is sent in, Lochart says. “This makes us the secret decoder ring,” he adds.

Lochart declined to specify which encryption vendors Postini will form partnerships with, but added that the company is in talks with two companies that will be announced in the second or third quarter. Pricing was not announced. The company already allows customers to encrypt messages using transport layer security (TLS), a network-level approach supported by many e-mail security vendors.

MailFrontier, which was acquired earlier this month by SonicWall, announced an upgrade to its e-mail security software and appliance, as well as a new compliance module.

MailFrontier Gateway 5.0 - available as either software or a dedicated appliance - includes new e-mail auditing capabilities, a traffic manager and a log manager, all designed to make everyday e-mail security tasks easier, according to company officials.
