ProHealth Care Prescribes NetScaler to Accelerate Medical Applications

Market Wire, July, 2005

NetScaler, Inc., the global leader in accelerated application delivery systems, today announced that ProHealth Care (PHC) has deployed the NetScaler application delivery system to a new, high-performance network being built by the health services provider. PHC selected the NetScaler based on its ability to enhance application response time while delivering superior global and application-specific load-balancing and security capabilities across a complex seven-layer network. The NetScaler helps assure high availability on PHC's new intranet service, which provides portals of critical information for thousands of physicians, clinicians and employees.

"High performance and high availability are our No. 1 criteria in building out the new network," said system architect William Bailey. "The superior application performance, security and global load-balancing capabilities of the NetScaler application delivery system are critical to our reliable delivery of clinical and diagnostic data, medical and business records, and other important information to the physicians, employees and patients who rely on highly responsive applications from our network."

Established in 1998, PHC, a not-for-profit corporation based in Waukesha County, Wis., provides a continuum of health services to Milwaukee and the surrounding area. Additionally, PHC provides outsourced medical information services to other health care providers regionally and nationally. With a network of more than 700 physicians and nearly 5,000 employees, the company's services range from education and health promotion to sophisticated hospital services.

Enhancing the delivery of enterprise applications across PHC's network is no simple task. "Ultimately, the same network will be responsible for handling all requests -- from massive clinical imaging files from physicians on high-speed clients, to appointment notifications for patients on a dial-up connection," Bailey said. "The NetScaler application delivery system has proven that it doesn't care -- it handles all application transactions quickly, reliably and efficiently. No other product we looked at even came close."

"In an industry that deals with sensitive medical data, fast transaction speeds, high security and high availability are absolute necessities," said Wes Wasson, vice president of worldwide marketing for NetScaler. "ProHealth Care's experience using the NetScaler application delivery system demonstrates that it is a mature technology capable of managing complex, heterogeneous environments. We are very proud to be selected to help an award-winning healthcare institution like PHC build out a network to deliver first-class care to its customers."
