Instant Information Deploys Blue Coat Appliances and SG Client for High Volume WAN Optimization

Blue Coat ProxySG Appliance and SG Client Accelerate Data Transfer Across WAN, the Internet, Branch Offices and Remote Employees

SUNNYVALE, Calif., Oct. 15 -- Blue Coat Systems, Inc. (NASDAQ:BCSI) , a leader in WAN Application Delivery and Secure Web Gateway, today announced that Instant Information, Inc. has selected Blue Coat(R) ProxySG(R) appliances and Blue Coat SG(TM) Client software to accelerate applications and reduce bandwidth consumption across its Wide Area Network (WAN), the Internet, branch offices and remote employees.

Instant Information's best-of-breed Web discovery technology enables business, finance and information professionals to receive relevant and targeted information from the wealth of content available on the Web today. Instant Information moves vast amounts of data into its data center as part of its internal operations. The company selected Blue Coat ProxySG appliances and SG Client software to accelerate the acquisition of these files and to reduce their overall bandwidth consumption.

"With hundreds of gigabytes of files crossing the WAN each day, we needed a solution that could accelerate high volumes of data to and from our data centers, branch offices and remote users," said Eli Feldman, vice president of engineering and operations, Instant Information. "Blue Coat ProxySG appliances and SG Client enable us to communicate, collaborate and share data and distributed applications in a way that stays ahead of the fast pace of our business."

"When information is the chief product or business of a company, the WAN represents a critical lifeline for them," said Kevin Biggs, senior vice president of Worldwide Sales, Blue Coat Systems. "We are pleased to help Instant Information optimize its network by accelerating the delivery of high volumes of data and distributed applications across its organization."

Blue Coat's MACH5 Acceleration Technology

Blue Coat ProxySG appliances utilize the company's MACH5 patent-pending framework of acceleration technologies designed to accelerate all key enterprise applications, including Web and secure Web applications (SSL), file services, email/Microsoft Exchange and live streaming or on-demand video. Since the MACH5 technology is integrated with Blue Coat ProxySG appliances, it enables organizations to manage all of their user/application interactions -- to stop undesirable applications, regulate less important applications and accelerate critical applications, even when encrypted using SSL.

Blue Coat SG Client Extend Application Delivery to Mobile Users

Blue Coat SG Client extends application delivery to mobile users and small branch offices, enabling application acceleration to the desktop. SG Client offers several acceleration and optimization techniques to provide a LAN-like end-user experience for telecommuters, mobile employees, remote third party contractors and others who need access to internal or hosted resources but are potentially thousands of miles away. Whether used to complement a branch office solution or simply to improve the application and file services performance for remote users connecting over VPNs, SG Client minimizes lost productivity and end-user frustration from sluggish applications and slow network performance.
