Network Appliance NetCache Provides Industry's First Caching Solution with Integrated Filtering; NetApp Also Delivers New Caching Appliance.

SANTA CLARA, Calif.--(BUSINESS WIRE)--April 27, 1999--

Network Appliance, Inc. (NASDAQ: NTAP), the leading provider of dedicated cache appliances for building Intranet and Internet infrastructure, today announced NetCache(TM) 3.4, the next-generation, high performance caching solution. Network Appliance (NetApp(R)) also introduced today a new caching appliance incorporating NetCache 3.4, designed for mid-size enterprises and Internet Service Providers (ISPs) who need an affordable solution to meet their performance needs.

NetCache is the first market-proven, scalable cache to incorporate SmartFilter(TM) by Secure Computing (NASDAQ: SCUR), providing customers with a fast, cost-effective way to administer corporate Internet/Intranet access policies, as well as grow network infrastructure and manage mission-critical data.

Science Applications International Corporation (SAIC), the largest employee-owned research company in the U.S., will use NetCache 3.4 to consolidate and scale access to its Intranet network. "We selected the NetCache solution because it provides the performance and feature-set we need to share information across our data networks," said Jeff Wade, network information specialist at SAIC. "The filtering feature will be especially important to us because we need a secure, cost-effective, high performance system to control and monitor access to the massive amount of research information available from the Internet."

"Enterprises require a solution that ensures Internet productivity," said Gus Maldonado, product marketing manager for SmartFilter at Secure Computing. "The combination of SmartFilter's advanced filtering technology with NetCache's end-to-end scalability, high performance and manageability offers both enterprises and ISPs a cutting-edge caching/filtering solution."

"Filtering has become a critical issue for corporations and ISPs," said Amit Pandey, director of NetCache for Network Appliance. "By closely integrating SmartFilter with NetCache, customers now have a scalable, cost-effective solution that increases network performance while managing access to sensitive information."

The NetCache Solution

NetCache 3.4 is incorporated into Network Appliance's complete line of caching appliances. Additional features include wide-area network (WAN) performance enhancements that optimize data transmission enabling NetCache to speed up both cached and uncached data.

NetApp's new C720s caching appliance, with 256 MB RAM and two 9 GB disk drives, builds on the high-performance offered in the NetCache C720 series, but is tailored towards the storage and performance needs of medium-size corporations, ISPs and ISP points-of-presence (POPs). The new appliance incorporates NetCache 3.4 and is priced starting at $18,000.

Network Appliance(TM) NetCache solutions, including SmartFilter, are available directly from NetApp (new sales inquiries call 1-800-443-4537; current customers call 1-888-2-NETAPP).
