Columbia, MD, August 5, 2003 - Sourcefire, Inc., a leader in protecting enterprises and government organizations against the threat of network attacks and misuse, today announced that it has achieved OPSEC™ (Open Platform for Security) certification for Sourcefire Intrusion Management System from Check Point Software Technologies Ltd. (NASDAQ: CHKP), the worldwide leader in securing the Internet. Through OPSEC certification, Sourcefire Intrusion Management System seamlessly integrates with Check Point's market-leading VPN-1®/FireWall-1® Next Generation™ solution, providing customers with increased protection from network attacks.

The integration of Sourcefire Intrusion Management System with Check Point's Next Generation with Application Intelligence™ security software provides users with industry-leading security to protect their businesses most critical networks and resources from attacks. Check Point's latest version of its market-leading product suite, Check Point Next Generation™ with Application Intelligence™, provides customers with the industry's only comprehensive, integrated security solution for defeating and preventing both network-level and application-level attacks. Sourcefire’s product works with Check Point VPN-1/FireWall-1 in real-time to block malicious traffic attempting to enter a corporate network. This intrusion prevention technique is another step in Sourcefire’s roadmap to provide users with a fully integrated security infrastructure, which will include detection, prevention, passive network discovery, behavioral profiling and vulnerability analysis.

The OPSEC certification combined with Sourcefire’s Intrusion Management System, now including the recently announced Real-Time Network Awareness‘ (RNA) technology, provides users with the industry's best defense against network attacks. Sourcefire RNA constantly monitors network assets for potential vulnerabilities while alerting administrators in real-time to anomalous network behavior.
