TIPPINGPOINT UNVEILS MANAGED SECURITY SERVICE OFFERING THROUGH ALLIANCE WITH COUNTERPANE

New Service Gives Customers Greater Flexibility for Management of Large-Scale Intrusion Prevention System Implementations

Austin, Texas - May 1, 2006 - TippingPoint, a division of 3Com and the leader in intrusion prevention, today launched a managed security service (MSS) for the award- winning TippingPoint Intrusion Prevention Systems (IPS), enabling enterprises to cost- effectively outsource and centralize the 24x7 management and monitoring of global, multi-site IPS deployments for a complete view of the organization's security health. The new service, available worldwide today, is the culmination of an alliance with Counterpane, the leading managed security company that supports over 550 enterprise networks and monitors data collected from more than 150 countries.

Tom Dunbar, global IT chief security officer of XL Global Services and a joint Counterpane-TippingPoint customer, said, "We are extremely pleased with the superior support and security we received from using award-winning, best-of-breed technology from TippingPoint and global management and security expertise of Counterpane. The companies have worked together as an integrated team to provide us with quick response times and access to information."

According to Gartner, the managed security service market was expected to generate over $1 billion in revenue for 2005.¹ Managed security services provide large enterprises with 24 hour-a-day monitoring, management, and correlation of security events from multiple devices at geographically dispersed locations for maximum visibility into possible threats. By outsourcing the management of multiple security and network devices, enterprises can obtain a holistic view of the network health and security posture.

Managed services can be used to obtain and show compliance with regulatory requirements like Sarbanes-Oxley, the Health Insurance Portability and Accountability Act (HIPAA), and Gramm-Leach-Bliley Act (GLBA) through reporting and documented processes. TippingPoint Intrusion Prevention Systems can also be used to comply with "best practice" regulations because they preemptively prevent worms, viruses, Trojans, Denial of Service attacks, Spyware, Phishing, and VoIP threats.

"The benefit of an IPS managed service over that of a traditional intrusion detection managed service is that it provides a proactive solution, blocking threats before damage occurs through real-time security intelligence, change control, and device management," said Don Ward, vice president of services and support for TippingPoint. "This alliance is changing the MSS model from incident response to proactive mitigation. Many global customers have requested a managed IPS service to cost-effectively maintain real-time network and security health through 24x7 monitoring and event correlation at multiple, geographically-dispersed sites."

In addition to providing managed security services for IPS platforms, the combined service from TippingPoint and Counterpane will provide management of other third party data center server resources and network devices so customers can aggregate events and correlate information in the core and perimeter portions of the network. This centralized information will give enterprises instant visibility into the general health of the network and possible threats, providing a strong value proposition to customers. By combining the management of IPS with firewalls, intrusion detection systems, and other network devices and data center assets, enterprises can cross-reference the information to optimize their IT investments and reduce operating expenditures.

As part of the alliance, TippingPoint equipment will be incorporated into Counterpane's existing Security Operations Centers (SOC) to provide premiere 24x7 monitoring and management support of the TippingPoint IPS product line. Counterpane's SOC engineers will have direct access to TippingPoint's premier support, training, and escalation security engineers at TippingPoint headquarters. This will ensure the same high quality performance and security of on-premise management with 24x7 SOC personnel monitoring all aspects of network security to meet enterprise mission-critical Service Level Agreements.

"Counterpane and TippingPoint both have a strong reputation for in-depth security expertise and a similar client base comprised of Fortune 1000 enterprise customers," said Bruce Schneier, Chief Technology Officer and Founder at Counterpane. "As recognized leaders in the managed services markets and intrusion prevention markets, we believe that we have put together an unsurpassed service offering that is bound for success."
