Tablus, PortAuthority Unveil Security Tools

Updates aim to boost protection against data thefts

Two new content-monitoring tools to be released this week will add to the growing number of options for security managers looking to protect sensitive data against compromises and theft.

Tablus Inc. in San Mateo, Calif., and PortAuthority Technologies Inc. (formerly Vidius Inc.) will both release updated versions of their respective technologies this week.

Tablus' upgraded hardware and software platform features a component called Content Alarm NW 2.0 for monitoring and blocking information leaks via the network and a component called Content Alarm DT 2.0 that's designed to do the same at the desktop level. The company touts it as the first content monitoring product designed to prevent data leaks at both the network level and at the desktop.

The product uses Google-like crawler technology to identify and "fingerprint" sensitive data such as financial or personal information. On a network, the Tablus tool monitors traffic to ensure that the fingerprinted data is not illegally transmitted out of the network via e-mail, instant messaging, FTP or any other means, said CEO Jim Pante.

A similar approach is being applied on the desktop side to ensure that users can't illegally modify, copy, delete or save protected data on thumb drives, external hard disk or private e-mail spaces, he said.

Such capabilities are crucial for protecting sensitive data, said Dmitriy Kalika, IT director at Amide Pharmaceutical Inc., a manufacturer of generic drugs in Little Falls, N.J. Amide's networks hold drug formulation information that is relatively easy to print out or download and spirit away in devices such as USB thumb drives and external storage devices, Kalika said.

"With Tablus, I can control what happens to the files," he said. "It does not allow anybody to do anything unless they have permission."

Data Recognition Corp., a Maple Grove, Minn.-based provider of educational testing and assessment programs, is using Tablus' network monitoring technology to protect test booklets, answer keys, scores and similar information, said Michelle Edenborg, the company's IT director.

All information that is transmitted out of the company's network is inspected for sensitive data by Tablus' appliance, she said.

Meanwhile, Beverly Hills, Calif.-based PortAuthority is enhancing its content monitoring product, PortAuthority for Internal Mail, with a function for scanning internal e-mails for signs of data misuse. The product, which already allows companies to monitor external e-mails, adds support for Microsoft Exchange 2003 internal e-mail and for ISA 2004 Web proxy servers.

"There is definitely growing interest" in tools such as these, said Dan Keldsen, an analyst at Delphi Group, a Perot Systems Corp. company in Boston. Compliance issues and fears of data loss are driving much of it, he said.

Also, network security vendors traditionally haven't paid a lot of attention to content protection and issues such as inappropriate use of information by insiders, which vendors of content monitoring tools are beginning to address, Keldsen said.


Tablus Content Alarm NW 2.0 and Content Alarm DT 2.0: Real-time network traffic analysis, linguistic analysis of both structured and unstructured data, and Google-like crawler technology for creating digital fingerprints of data. Designed to protect sensitive data on both network and desktop levels. Pricing starts at $25,000 for the departmental edition; the enterprise edition starts at $75,000.

PortAuthority for Internal Mail: Designed to prevent leaks of confidential information between internal e-mail users. Supports Microsoft Exchange 2003, Lotus Domino and Exchange 2000.
