Net-Sieve launches filtering tool

Net-Sieve Inc. announced on Monday an Internet filtering tool aimed at the enterprise that watches out for spam, pornography, and viruses.

The Austin, Tex.-based company’s Net-Sieve 250 runs on an Intel box and Red Hat Inc.’s Linux software. It tags incoming e-mail as spam or pornography and blocks pornographic Web sites and redirects or tags questionable ethical phrases from e-mail. Additionally, it will perform a URL “black list.”

“You have the ability to black list and white list sites or we actually look at the content as you go to a new site. We analyze the content as (users) go there,” said Dewey Coffman, president and CEO at Net-Sieve in Austin.

It is the hardware that is responsible for the filtering, he said, and the product is aimed at organizations with at least 200 employees.

The 250 uses a proprietary approach by using an algorithm detection system to decipher the unwanted electronic text. It is packaged as a stand-alone, single unit that sits either in front of or behind the company’s firewall and is positioned between the Internet router or cable modem and the local e-mail server.

With a zero-tolerance approach, Coffman added it has the ability to put up a warning screen alerting the user that the page “contains pornographic content” and has been or will be blocked by the administrator.

The Net-Sieve 250 starts at US$20,000 and includes both the hardware and software. It can handle 250 simultaneous users.
