ACNielsen Enhances Customer Service Using BackWeb Software.

World's Leading Marketing Information Provider Uses BackWeb Solution to Automate Synchronization of Large Amounts of Data to Its Customers

SAN JOSE, Calif. -- BackWeb Technologies Ltd. (NASDAQ: BWEB), a leading provider of software designed to mobilize existing enterprise applications, announced that its software has been deployed by ACNielsen, a VNU business (ASE: VNU). ACNielsen uses the BackWeb software to create a fully automated, just-in-time data delivery chain that makes use of low cost synchronization over a virtual private network.

Information freshness is a key competitive advantage for ACNielsen and its customers. ACNielsen collects retail sales data on a large number of fast-moving consumer packaged goods. Consumer packaged goods brand managers and other customers subscribe to this critical data to spot important business trends, market conditions and sales results. It is imperative the data be accurate and timely. Customers often need to work with large amounts of data in their own business intelligence systems. ACNielsen uses the BackWeb software to provide a service that automatically synchronizes the subscribed data from its data warehouses to customer locations. These customer data packages can be quite large, nearly a gigabyte in size, requiring the ACNielsen delivery system to be scalable and be able to deliver data reliably and securely over the internet without causing network congestion. BackWeb's flexible data acquisition and delivery capabilities enable the ACNielsen service to capture and deliver data in a 'polite' and 'light' way. As a result, ACNielsen customers can consistently and accurately analyze and act on the most current market data available, and ACNielsen can track and audit their customer data synchronizations to monitor service levels.

"BackWeb allows us to efficiently and quickly deliver data to our clients," said Mike Venaccio, Senior Manager Technical Administration at ACNielsen. "The incremental update process is key to keeping bandwidth costs at a minimum."

"BackWeb software is used by Fortune Global 1000 companies to achieve reliable synchronization of their applications and data to remote and mobile audiences," said Bill Heye, Chief Executive Officer of BackWeb. "ACNielsen is one of many companies who rely on BackWeb to provide a seamlessly automated content delivery system that is both secure and economical. We are committed to helping ACNielsen and all our customers achieve cost savings and greater productivity for employees, partners and customers by synchronization of key data and web applications."
