Palo Alto, Calif. – December 7, 2004 – MailFrontier™, a pioneer in email security and leading provider of anti-spam and anti-phishing solutions, today announced that it has been selected as a Top 100 Innovator by Red Herring.

"We are proud to be part of the Red Herring Top 100 Innovators, and thrilled that the editors have acknowledged our innovation and leadership in email security," said Anne Bonaparte, president and CEO of MailFrontier. "Threats to email are increasing at alarming rates. Phishing, spam, viruses - all of these further the breakdown of email as a trusted and productive business communication medium. MailFrontier is committed to making email good again and to building on our innovations in anti-spam and anti-phishing technology, and most recently technology to block zero-hour email virus outbreaks."

"Selection for the Innovation 100 puts a company in an elite group. The editors worked hard to identify the companies that will be driving the important technology trends in the coming years," said Joel Dreyfuss, Editor-in-Chief of Red Herring.

Red Herring's editorial staff evaluated over 1,200 submissions from 900 companies. The editors used a careful analysis of financial data as well as subjective criteria, including quality of management, execution of strategy, and dedication to research and development.

The Red Herring Top 100 Innovators will be unveiled at the Red Herring Fall 2004 conference, Dec. 6-9, 2004 at the Monterey Plaza Hotel in Monterey, Calif.
