MRIS Secures Network With NetScreen Security Solutions

Sunnyvale, CA - February 12, 2003 - NetScreen Technologies Inc. (Nasdaq: NSCN) today announced that Metropolitan Regional Information Systems Inc. (MRIS), one of the largest real estate information service providers in the nation serving over 4,000 broker offices, has selected NetScreen's integrated security solutions to establish virtual private network (VPN) connections and allow brokers to create a secure environment for their office networks.

Before deploying NetScreen's solutions, brokers connected to MRIS via dial-up, frame relay or leased-line connections. This complicated network management and generated enormous communications costs for MRIS and its customers.

In order for customers to take advantage of broadband capabilities, MRIS created a secure, homogenous point-to-multi-point network architecture leveraging NetScreen systems and appliances. MRIS now uses paired NetScreen-500 systems, purpose-built integrated firewall and VPN appliances, centrally located at the company's corporate headquarters to secure the data warehouse and serve as VPN concentrators. MRIS provides subscribing customers NetScreen-5XP or NetScreen-5XT integrated firewall and VPN appliances to ensure high-speed, secure access to the system from remote broker sites.

Since deploying the NetScreen solution, MRIS has eliminated expensive, privately leased ISDN lines, saving significantly on connectivity-related costs. MRIS also enjoys the ability to help small- to medium-sized real estate brokerages with limited IT resources quickly deploy their client-side VPN devices and remotely manage the devices from a central site.

"The economics of our service offerings simply would not be possible if we had to expend internal IT resources to travel to customer locations and laboriously configure each VPN connection," said Doug Eddy, technical solutions integrator for MRIS. "With NetScreen's devices, we can simply pre-configure an appliance, ship it directly to a customer, and trust that they can quickly deploy it to establish secure and reliable access to the system."

"A reliable VPN network was required for MRIS to evolve its business model. A complex and difficult-to-configure software solution would have been too time consuming and costly for MRIS and its customers to execute," said David Flynn, vice president of marketing at NetScreen. "With NetScreen's purpose-built, appliance-based solutions, highly distributed enterprises like MRIS can enjoy the benefits of a secure, high performance VPN with minimum management overhead."
