Yahoo Selects Abaca's Email Security Solution

PRESS RELEASE

Abaca Technology Corporation, an innovator in email protection and messaging security, announced today that Yahoo! Inc. will use Abaca's patented email security solution to help protect Yahoo! users from spam, phishing, and other email-borne attacks. Abaca's solution is the only one in the industry that guarantees at least 99% accuracy in filtering email.

"As one of the world's leading Internet companies, we take the security of our users very seriously," said John Kremer, vice president of Yahoo! Mail. "Abaca offers superior e-mail security capabilities and has built a reputation for reducing unsolicited e-mail within mailboxes. We believe that by deploying Abaca's solution with our anti-spam toolkit, we will offer Yahoo! Mail users not only added email security, but an enhanced user experience as well."

Abaca's email security solution is a next-generation technology that uses the receiver's reputation to calculate whether an incoming message is legitimate. Once the Abaca solution is installed, protected users immediately become members of the Abaca ReceiverNet(tm) Protection Network, which provides zero-hour email security with a guaranteed minimum of 99% accuracy.

As more users are added to the Abaca ReceiverNet Protection Network, it becomes increasingly accurate in assessing threats from spam and other online attacks without any additional system tuning required. This scalable intelligence makes Abaca's email security solution ideal for internet service providers (ISPs) who must protect large and growing user communities.

Abaca's solution has already been deployed by Terra, the largest Internet Company in Latin America and by a number of regional ISPs in the United States, including Roggen Telephone Enterprise Broadband (RTEBB), Netrique and sCs Technologies.

"Abaca has proven that our solution scales seamlessly to deliver high level of protection to small businesses, large enterprises, regional ISPs, and service providers with millions of email users. Now one of the largest Internet companies has given us an unprecedented opportunity to make a global impact in the fight against spam, an extremely gratifying validation of our technology and our business model," said Bill Kasje, Abaca's vice president, business development, "We are tremendously honored to be working with Yahoo! to protect hundreds of millions of Yahoo! Mail users around the world."

Since launching its award-winning email security solution in October 2007, Abaca has successfully eliminated spam and other email-based attacks for a diverse and demanding customer base that includes businesses, nonprofits, school districts, higher education and ISPs. The company's ReceiverNet technology ensures that all customers achieve at least 99% accuracy in filtering email, a figure recently confirmed by The Tolly Group.
