AUSTIN, Texas--(BUSINESS WIRE)--April 26, 2004

TippingPoint Technologies Inc. (Nasdaq:TPTI), the leader in intrusion prevention, today announced that the University of Texas McCombs School of Business (McCombs), ranked as the 13th best MBA program in the world by the Wall Street Journal in September 2003, has implemented the UnityOne(TM) Intrusion Prevention System to protect their network from internal and external cyber threats.

TippingPoint Technologies' President and COO James Hamilton said, "UnityOne is a powerful system designed to help our customers eliminate cyber threats and fortify their network. UnityOne's powerful performance combined with frequently-added Virtual Software Patches help shield the McCombs network from cyber threats, walk-in worms and bandwidth hijackers."

In addition to blocking external cyber attacks and internal threats such as 'walk-in' worms carried in on laptops, UnityOne also increases bandwidth availability by enabling administrators to control peer-to-peer traffic and Instant Messaging. Administrators are able to block or throttle traffic by IP address or application, enabling organizations to reclaim valuable bandwidth.

Using specialized hardware and custom chips, UnityOne inspects traffic through Layer 7 at gigabit speeds to block malicious traffic. UnityOne utilizes a combination of complex algorithms, vulnerability-based Virtual Software Patches, and statistical anomaly filters to stop Denial of Service attacks and zero-day exploits. UnityOne traffic normalization enforces protocol compliance and reclaims wasted bandwidth. The end result is a faster and safer network.

TippingPoint's UnityOne provides Application Protection, Performance Protection and Infrastructure Protection at gigabit speeds through total packet inspection. Application Protection capabilities provide fast, accurate, reliable protection from internal and external cyber attacks. Through its Infrastructure Protection capabilities, UnityOne protects routers, switches, VoIP gateways and other critical infrastructure from targeted attacks and traffic anomalies. UnityOne Performance Protection capabilities enable customers to throttle non-mission critical applications that hijack valuable bandwidth and IT resources, thereby aligning network resources and business-critical application performance.
