RED HERRING 100 NORTH AMERICA

SAN JOSE, CA, April 5, 2006 - Red Herring announced that A10 Networks has been short-listed as one of the top 200 contenders for its annual "Red Herring 100 North America" list. Well over 1,000 privately held technology companies submitted to this year's edition of the prestigious award, giving evidence to the invigorated innovative and entrepreneurial strength of the technology ecosystem. As one of the finalists, A10 Networks will join the exclusive Red Herring Spring 2006 CEO summit, May 23-25 in Monterey, California, where the technology industry's most innovative CEOs, venture financiers, and corporate strategists will gather to meet the next wave of disruptive companies.

High-quality companies
"We can see the resurgence of the tech sector reflected in the quantity and variety of excellent companies that we had to choose from in putting our list together," said Joel Dreyfuss, Editor-in-Chief of Red Herring. "It was difficult to choose the 200 finalists and we are very happy with the stellar quality of the companies on this shortlist."

A10's products combine centralized user account management, identity correlation, identity-based reporting, user self-help services, and authentication in a hardened, drop-in appliance. A10's first product, the IDsentrie system, unites the most popular Identity and Access Management features with networking and security devices to deliver centralized, automated identity resource management and unparalleled visibility into network activity. Industry research firm IDC expects the worldwide Identity and Access Management market will double over the next three years from approximately $2B today to more than $4B in 2009.

More than just buzz
The "Red Herring 100 North America" award is an important part of Red Herring's tradition of recognizing new and innovative technology firms and their entrepreneurial founders. A10 Networks and the other nominees were rigidly evaluated on both quantitative and qualitative criteria such as financial performance, technology innovation, quality of management, execution of strategy, and integration into their ecosystem. This unique assessment of potential complemented by a review of the actual track record and standing of a company allows Red Herring to see past the "buzz" and make the list an invaluable instrument for discovering and advocating the greatest business opportunities in the industry.

Bringing together the best
As part of this tradition to honor innovation and entrepreneurship in the business of technology, Red Herring will again host "Red Herring Spring," a two day invitation-only summit for the CEOs and founders of the Red Herring 100 winners and finalists in Monterey, California. The summit's C-level attendees will convene under the theme "The Pursuit of Disruption" to discuss major trends and opportunities and to explore partnerships, alliances, investments, and M&A activities.
