Narus Gains Entry Into Coveted Chinese Carrier Market With Shanghai Telecom as First Regional Customer

Shanghai Telecom Leverages NarusInsight to Detect and Manage VoIP Traffic on its Network

MOUNTAIN VIEW, Calif.—April 5, 2006—Narus, Inc. today announced that it has penetrated the Chinese telecommunications market with its first customer win in the region, Shanghai Telecom Co., Ltd. Through the use of the ultra high-performance NarusInsight™ IP traffic processing system, Shanghai Telecom will be able to detect and mitigate rogue VoIP traffic on their network, enhancing the quality of experience for the users of properly configured and authorized VoIP services.

In an effort to provide the highest-quality VoIP experience to its customers, Shanghai Telecom turned to NarusInsight’s ability to provide a total network view by performing deep-packet inspection (layers 2 through 7) of IP traffic, while correlating across every link of the network at extremely high speeds. This total network view is essential to the security, management and deployment of Shanghai Telecom’s IMS-based services such as VoIP, IPTV, PTT, etc. This is Narus’ first installation in China, and comes on the heels of an unprecedented agreement with the China Information Technology Security Certification Center (CNITSEC), which recently certified NarusInsight to protect China’s major telecom carriers against network attacks.

Designed in conjunction with a mitigation system from local Chinese partner and system integration from CommVerge Solutions, the Shanghai Telecom system leverages NarusInsight’s VoIP Discovery application module to detect and analyze incoming VoIP traffic to correctly determine whether that traffic is authorized or not. If the VoIP traffic proves to be unauthorized, NarusInsight alerts the mitigation system to take action and block the traffic. “Shanghai Telecom prides itself in providing the very best IP services to its customers,” said Pu Chen, Chief Technical Director, CommVerge Solutions. “NarusInsight’s unique combination of deep packet inspection and complete correlation will allow Shanghai Telecom to more accurately detect unauthorized traffic and take the actions necessary to ensure the health and quality of the services Shanghai Telecom provides to their valued customers.”

“Narus is the worldwide leader in providing the real-time network insight essential in securing, managing and delivering services over IP,” said Dr. Weiming Li, vice president and general manager, Narus Asia/Pacific region. “By deploying NarusInsight, Shanghai Telecom not only has the critical VoIP detection and management capabilities required today, but also the ability to easily expand their system to provide the security, management and intercept capabilities required by all of their IP services as their portfolio grows.”

NarusInsight provides carriers with the only complete view of all the IP traffic on their network, supporting unrivaled early detection of anomalies and threats, while also classifying real-time IP services such as VoIP and Skype for management and quality-of-service applications. NarusInsight is the only packet-processing system that provides both high-speed deep-packet inspection from layer 3 to layer 7, while also correlating traffic across all the links and elements on the entire network. Installed by Tier 1 carriers around the world, NarusInsight has the field-proven ability to meet the most stringent requirements of the world’s largest networks.
