PRESS RELEASE

IRVINE, Calif. " Sendio, Inc., an innovative e-mail security company with solutions that incorporate the human element to totally eliminate spam and e-mail threats in the enterprise environment, announced today it secured $3 million in Series B funding from lead investor Athenian Venture Partners, along with previous institutional investors Vicente Capital Partners (formerly Kline Hawkes), Shepherd Ventures and Momentum Venture Management. In addition, Athenian Venture Partners' Senior Partner Franois Hlou joined Sendio's Board of Directors. The capital investment will help fund the expansion of the company's sales and marketing initiatives for its E-mail Security Platform (ESP), a robust and scalable appliance solution for the enterprise which entirely eliminates spam and e-mail threats, enabling dramatic time savings for users and IT administrators.

Sendio's unique anti-spam technology landed this Series B investment despite the challenging economic environment, reaffirming the increasing demand for enterprise security solutions that protect organizations from data breaches, viruses, botnets and other threats. According to a recent Dow Jones VentureSource report, Southern California's fourth quarter venture capital numbers dropped for the first time since 2003, down more than 18 percent annually. However, Southern California's IT industry actually experienced an increase in investments, bucking the national economic trend. The growth of Sendio's sales and marketing efforts will also significantly expand their customer reach, particularly in vertical markets and via the company's channel partners, and continue to build strong shareholder value.

"We believe that we are way ahead of the curve in terms of anti-spam technologies, and also that given the current state of our economy, even more vicious spam and virus attacks will take place as spammers try to take advantage of the situation," said Kevin Bowyer, CEO of Sendio. "This $3 million investment from our existing investors, and Athenian Venture Partners, confirms our strength and future growth."

An E-mail Security Platform That Works Sendio's E-mail Security Platform is the only challenge-response solution designed specifically for the enterprise. The ESP obtains its effectiveness through a combination of SilverListing, a proprietary technology that includes a set of low-level SMTP tests to determine the legitimacy of the sending e-mail server, and Sender Address Verification (SAV), which verifies the authenticity of first-time, unsolicited senders, and introduces a human element into the process. Sendio's ESP far surpasses the capabilities of current spam filter offerings and finally secures the enterprise inbox through the complete elimination of spam.

"Under the strong leadership of Kevin Bowyer and his team, Sendio continues to build upon a robust and differentiated technology, making the company well-positioned to continue its rapid growth," said Franois Hlou, senior partner at Athenian Venture Partners. "We firmly believe that, particularly in this economic environment, there will continue to be a high level of demand for Sendio's E-mail Security Platform as organizations begin to realize that spam filters just do not work."
