AppRiver is First to Integrate Akamai’s Application Performance Solutions into Exchange Hosting Service

GULF BREEZE, FL, September 12, 2007 – AppRiver LLC, a leading provider of email security solutions, today announced it is the first Microsoft Exchange Hosting provider to utilize Akamai Technologies, Inc. (NASDAQ: AKAM) Application Performance Solutions to increase the performance, availability and scale of its secure hosted exchange service, providing customers with faster performance and more reliable connectivity at no additional cost.

The Akamai Application Performance Solutions platform transforms the Internet into a business-quality application delivery infrastructure by bringing performance, scale, visibility and control to mission-critical applications delivered over the Internet. It combines a global network of 25,000 specialized servers with Akamai’s proprietary transport and routing protocols to offer global sub-second response times, secure delivery and control of applications from a single, centralized data center to meet the needs of customers, partners and employees around the world.

By implementing the Akamai platform within its service, AppRiver ensures that Internet disruptions such as circuit failures, which are typically out of the control of a hosting company, can be dynamically avoided. This assures that users will always have quick and reliable access to their Outlook and Outlook Web and Mobile Device applications, regardless of their location or what is happening on the Internet. The enhancement will prove especially beneficial for AppRiver customers who use Hosted Exchange on handheld devices as well as multinational companies and businesses with multiple branch offices.

The integration improves the scalability of AppRiver’s business by reducing support costs and making its operations more efficient, allowing the company to provide enhanced Hosted Exchange service for all its customers without an increase in price.

“AppRiver is excited to become the first Hosted Exchange provider to use Akamai, which is the most comprehensive platform for content delivery and application acceleration,” said Michael Murdoch, AppRiver’s CEO. “Implementing Akamai within our service makes it possible to achieve LAN-like network consistency, performance and reliability over the Internet, allowing us to provide an easy, effective and affordable Hosted Exchange solution for our customers worldwide.”

“As a leader in the Microsoft Exchange Hosting market, AppRiver understands the need for high performing, always available applications,” said Willie M. Tejada, vice president of Application Performance Solutions Product Line for Akamai. “We are pleased we could work together with AppRiver to deliver an industry-leading solution leveraging Akamai’s Application Performance Solutions platform.”

Michael Osterman, president, Osterman Research, a leading analyst firm in the messaging and collaboration space, commented on the announcement, “Businesses today face increasing pressure to ensure performance and reliability of mission-critical communications for a far-flung network of employees, including the growing number of workers connected through wireless networks. AppRiver is addressing this challenge for Microsoft Exchange users through its innovative deployment of the Akamai solution.”

Targeted at the corporate, government and educational markets worldwide, AppRiver’s Exchange Hosting with Shoreline™ reduces the complexity and investment required to provision and maintain Microsoft Exchange email and collaboration solution. Built from scratch by AppRiver, the Shoreline Control Panel empowers administrators by providing a web-based Outlook configuration wizard that allows them to set up accounts, access email settings for mobile devices, view mailbox usage and reset their own passwords.

AppRiver’s Exchange Hosting environment features a redundant architecture that eliminates the possibility for a single point of failure. The hosting facilities are SAS 70 level II audited semi-annually, and Microsoft-certified staff members are on site to provide any necessary technical support.
