Comcast Zeros In On Spammers

Operator Deploys Cloudmark's Spammer-Monitoring System

By Todd Spangler -- Multichannel News, 10/26/2009 12:01:00 AM

Comcast now is trying to cut off spammers before they unleash torrents of junk e-mail.

The operator in the third quarter deployed a "sender reputation" service from San Francisco-based Cloudmark to pinpoint potential spammers. Comcast has already been using the Cloudmark Authority system to protect the 25 million e-mail accounts it hosts from spam, viruses and phishing attacks.

Terms of the expanded deal were not disclosed. Comcast, the nation's biggest cable operator, had 15.3 million high-speed Internet customers as of the end of June.

Cloudmark's Sender Intelligence includes data regarding spam resulting from bot infections on Comcast's network, and serves as a component of the MSO's new Constant Guard security program.

The Cloudmark sender-reputation service uses data from multiple sources. In addition to analyzing traffic patterns, the system incorporates user feedback and spam-correlation statistics to calculate sender reputation scores "in near-real-time," the company claims.

Cloudmark's customers include Cox Communications, Cablevision Systems, EarthLink and Swisscom.

• Big Brother Has a Name, and that Name is CLOUDMARK: This 1984-ish content-based "spam signature" filter gives Network Solutions and other web hosts and ISPs complete control over what emails YOU are allowed to send or receive. They can define whatever they choose to be a "spam signature", including the name of a cause they don't support, or the business telephone numbers of people who do. Here is how I know: tinyurl[dot]com/Cloudmark
