McAfee Offering Security Service for E-Mail

McAfee announced today that they are immediately offering a managed security service for email aimed at small to medium sized businesses.

McAfee, which was once known as Network Associates, has turned a service agency with Managed Mail Protection, a spam-, content- and virus-filtering service that detects and quarantines infected e-mails and inappropriate content before they enter the customer's network, the company said. Subscribers can obtain detailed information about quarantined e-mails through Web-based management reports.

McAfee's new service follows its competitor Symantec's move into the managed e-mail security market through the purchase of anti-spam company Brightmail in May.

Pricing is designed to appeal to small companies' budgets. "Our list price for a 200-seat installation is US$2.61 per user," Wai said.

The Technology -
McAfee's managed e-mail security service uses six levels of rules-based protection, as well as screening for viruses in incoming and outgoing messages, the company said.

The techniques used include heuristic detection, which involves the service asking questions about each e-mail to determine whether it is spam. The service also looks at each message's header, layout and organization. Customers can define their own lists of senders whom they want to block or allow.

Managed Mail Protection uses a statistical method known as "Bayesian filtering," which involves such tasks as analyzing the number of times certain words occur, to judge whether an e-mail is legitimate. Spam e-mails often use highly predictable or recurring language.
