Two-pronged tech aims to plug data leaks

Tablus promises to monitor both networks and desktops to help prevent the escape of a company's confidential information.

Information security provider Tablus is expected to unveil on Monday a two-pronged approach to stopping leaks of sensitive corporate information.

The company has integrated its Content Alarm NW product for networks with Content Alarm DT for desktop computers, which is based on technology picked up in Tablus' recent acquisition of Indigo Security. The package aims to provide a single dashboard to monitor and manage data to prevent it from being copied, printed or transmitted in violation of a company's policies.

"Our customers said they?didn't want to manage two separate monitoring reports, two separate policies," said Jim Nisbet, Tablus' chief technology officer.

Companies are increasingly becoming concerned about sensitive information leaving their corporate networks and employees' computers, especially since new federal regulations, such as the Sarbanes-Oxley Act, have kicked in.

Tablus' technology promises to analyze a range of data types, from databases to word-processing documents to source code. It will check the data whether it's moving across the network, being copied from a computer onto a small storage device or transmitted via e-mail.

"Everyone in the security world realizes there is not just one perimeter that needs protection," said Dan Keldsen, an analyst at the Delphi Group.

Tablus, based in San Mateo, Calif., plans to begin full shipments of the Content Alarm combination in July. It will offer three sensors, a controller and licenses for up to 500 desktops for $75,000.

Another leak prevention company, PortAuthority Technologies, is expected to announce a new e-mail security feature on Monday. The company, formerly named Vidius, plans to add monitoring of internal e-mail to its coverage of Web-based e-mail and of messages sent outside a company.

PortAuthority for Internal Mail promises to check communications sent within a company over Microsoft Exchange and Lotus Domino to make sure they don't let workers in authorized departments--such as human resources--send social security numbers and other confidential information to unauthorized employees.
