DAK -- Deutsche Angestellten-Krankenkasse Manages Nationwide Network with NETSCOUT nGenius Solution

November 19, 2003

Germany's Second Largest Health Insurance Society Uses NetScout To Improve Cost Efficiency and Service Quality for LAN & WAN Infrastructure

WESTFORD, Mass., Nov. 19 /PRNewswire-FirstCall/ -- NetScout Systems (Nasdaq: NTCT), a leading provider of enterprise-wide network performance management solutions, today announced that another leading company, Deutsche Angestellten-Krankenkasse (DAK), has chosen the nGenius(R) Performance Management System. With 6.5 million insured, DAK is the second largest health insurance society in Germany. The insurer uses the nGenius(R) Solution for the centralized monitoring and management of its nationwide LAN/WAN infrastructure. DAK's data centers in Hamburg provide 16,000 users and 1,000 branch offices with standard office applications and health insurance-specific applications hosted on several hundred server systems. NetScout's solution plays a strategically important role in controlling the cost of WAN links for this large network by ensuring high efficiency and overall quality of network service.

In 2002, DAK successfully migrated its 3270-type terminals to a Citrix Thin Client structure, which today encompasses 12,000 terminals and 17,000 network devices. Eleven nGenius(R) Probes were deployed to monitor the WAN links during the migration. Since then, a further 16 probes have been deployed within the company's WAN and LAN environments to monitor and proactively manage the performance of the new network and the response times of business-critical applications.

DAK has only positive experiences to report: "Without a tool such as the nGenius System, it would be impossible to monitor the LAN and WAN structure of an enterprise with 1,000 branch offices efficiently," said Bernd Krause, team leader, networking, at DAK's Hamburg data center. "NetScout is without a doubt the best performance management solution for an infrastructure of our size. It helps us achieve cost control, higher user productivity and clear information regarding the quality of network service."

DAK contracts with external network providers for the provisioning of WAN links. The cost of those lines are a major stress on DAK's IT budget, thereby increasing the importance of the nGenius Solution's ability to independently validate and report on the network service levels delivered by a provider. Should data communications be disrupted, NetScout boasts very good analytical capabilities. Application and network performance problems are solved faster so employees can more quickly resume productivity. Further, the nGenius Solution delivers accurate information on network health and resource consumption to DAK's management team.

"We will continue to update our network in accordance with future technological innovations, costs and possibilities," continued Krause. "NetScout will play a major role in our plans and should grow alongside our infrastructure. We are convinced that our working relationship with NetScout will continue to be as positive as it always has been. Their support is, without exception, positive."

"The DAK project reflects upon our growing global business in providing performance management solutions to the healthcare industry," said Jim Frey, vice president of marketing at NetScout. "Our nGenius Solution and its underlying CDM(TM) Architecture offer a high business value proposition to companies such as DAK by unifying key network performance management functionalities within a single tool. In addition, NetScout offers investment protection by assuring that the various types of management data found in DAK's network and applications infrastructure are leveraged for unified management decisions."
