• Company's global breadth and technical depth enables same day software updates
• Spokespeople available to discuss TCP security issues

ALAMEDA, Calif., May 10, 2004 - Wind River Systems, Inc. (NASDAQ: WIND), the global leader in device software optimization (DSO), successfully helped its customers to address the security threat posed by vulnerabilities in the TCP network protocol that leaves connected devices, traditional computers and servers open to denial-of-service attacks. Wind River released immediate software updates for its VxWorks operating system within hours of the official announcement, enabling its customers to safeguard their products quickly and efficiently. Wind River's global breadth and technical expertise allowed the company to be a first responder.

TCP is the foundation of most networks, including the Internet. The current security vulnerability stems from a shortcoming in the original TCP specification and affects all software that uses it, leaving any computer system or device that is connected to a network open to denial-of-service attacks.

"With the flow of information between the Internet, enterprise, desktop and connected device, Cybersecurity is a paramount concern. The ability for a company to respond immediately to a new security issue and quickly provide its customers with secure systems is critical. Wind River's successful management of the TCP vulnerability illustrates how they understand their customers," said Stephen Balacco, embedded software analyst, Venture Development Corporation.

"As the leader in device software optimization, it is our duty to set the standard for addressing security threats and helping our customers diminish risk wherever possible," said Dave Fraser, chief marketing officer, Wind River. "We are able to do this through the depth and breadth of our engineering team and our investment in customer support infrastructure. No other device software company in this market can come close to this level of service and responsiveness."
