Pivotal Dynamics Selects Corvigo's AI-Based Intent-Based Filtering

Technology to Stop Cox Communications' Costly Spam Problem

Corvigo, the creator of Intent-Based Filtering (IBF) for unwanted email, today announced that Cox Communications Middle America has become the first known ISP in the United States to successfully test and deploy artificial-intelligence-based technology to fight the costly spam epidemic. Deployed through systems integrator Pivotal Dynamics, the technology called Intent-Based Filtering(TM) (IBF), is deployed inside Corvigo's MailGate appliance or integrated into an MTA and accurately determines the intent of e-mail messages.

"We are glad that Pivotal Dynamics recommended Corvigo to solve our spam problem," said Jeff Strout, Director of IP Services of Cox Communications Middle America. "We plugged in the boxes and in less than 30 days, we reduced the load and increased performance on our mail servers almost by half. It has been an amazing ROI based on server performance and customer satisfaction. For our subscribers, we experienced almost immediate benefits with 95% of junk email captured without legitimate messages being lost. On the management side, we reduced the manpower required for after hours support on mail servers, and because IBF is a pure-play technology, rather than dozens of techniques, it requires no updates and less than 30 minutes per month to manage. It just sits in the rack and kills spam."

About Intent-Based Filtering Technology -- "Technology vs. Technique"

Corvigo provides e-mail filtering solutions based on its proprietary IBF technology. IBF technology uses Artificial Intelligence (AI) to determine the intent of information. The first application of Corvigo's IBF technology is the Company's MailGate(TM), a hardware appliance that sits behind a company's firewall and in front of its e-mail server. Unlike other solutions that send updates every minute or two, Corvigo's technology approach requires no updating -- cutting down on the management requirements associated with most anti-spam techniques currently on the market. Furthermore, while no other anti-spam technology can read and filter e-mail the way a human does when sorting through e-mail, Corvigo's patent pending technology-forward approach enables the company to address this simple concept. According to user studies, people sort mail as legitimate (family letters, bills, etc.), bulk (magazines, catalog subscriptions) or junk mail (unsolicited fliers, etc). Corvigo's technology solution is able to identify e-mail in the same fashion. As a result users receive important legitimate mail along with filtered message reports identifying junk and bulk mail that was kept on the MailGate and away from the mail server.

"Pivotal became the first systems integrator to offer IBF technology to our clients because we saw it in action," said Elsa Martin of Pivotal. "We have major customers that demand the latest technologies to solve problems or create revenue opportunities. Corvigo's MailGate lets Cox save money while providing a more satisfactory and rewarding experience for their customers. This will ultimately result in more customers for Cox."

About Corvigo

Corvigo provides e-mail filtering solutions based on its proprietary Intent Based Filtering (IBF) technology. IBF technology uses a proprietary, patent-pending AI-based technology to read each new e-mail message and determine the intent of the information, rather than relying on ineffective blacklists and rules. The first application of Corvigo's IBF technology is the Company's MailGate(TM), a hardware appliance that sits behind a company's firewall and in front of its e-mail server.

IBF technology is not a software or subscription-based service. It is an integrated plug-and-play technology that does not require system updates or routine maintenance to stop spam. For more information on Corvigo, and its services, please visit www.corvigo.com.
