Narus Signs Agreement with VeriSign to Allow IP Compliance and Security Products to Be Offered as Managed Services.

MOUNTAIN VIEW, Calif. -- Narus, Inc. today announced that it has signed an agreement with VeriSign, Inc. (Nasdaq:VRSN), the leading provider of intelligent infrastructure services for the Internet and telecommunications networks, allowing VeriSign to offer the entire suite of Narus products to its global customer base as managed services or licensed software. This includes capabilities for security, traffic analysis and lawful interception.

The first Narus product being offered by VeriSign is Narus LI for IP lawful intercept, one of the industry's most comprehensive IP lawful intercept products for carrier-grade networks. The product has been integrated into the VeriSign NetDiscovery(TM) service -- which is a cost-effective alternative to building an in-house proprietary lawful interception solution -- that meets the legal, technical and operational requirements needed to support end-to-end compliance for circuit-switched or IP-based technologies. The service helps providers that are responding to requests for collection of subscriber information, historical billing, call detail records and real-time lawful interception.

"VeriSign is the leader in delivering intelligent infrastructure services that enable and protect interactions across voice and data networks," said Raj Puri, vice president, Communications Business Development, VeriSign. "This agreement with Narus allows us to leverage the Narus highly scalable carrier-grade platform to extend our leadership in IP security and compliance management."

NarusSecure, Narus LI, NarusAnalyze and NarusMediate are part of the industry's only complete, high-performance IP security and monitoring system that can be implemented at the network core to analyze and correlate traffic in real-time. The Narus system gives customers the power to dynamically secure their entire network, while managing critical next-generation IP services such as VoIP, IMS and IPTV. Narus enables the flexibility for carriers to quickly adjust to market trends and changing regulatory mandates while providing the infrastructure to manage, protect and create new services -- all on a single common platform.

"Narus has built a global reputation for providing the industry's highest performance IP security and monitoring system, protecting many of the world's largest and most critical networks," said Greg Oslan, CEO, Narus. "This agreement will marry VeriSign's unparalleled brand with the scalability and flexibility of the Narus system to create the industry's most complete suite of managed services for IP networks."
