Corelight delivers the most powerful network visibility solutions for information security professionals, helping them understand network traffic to detect, stop, and remediate cyber attacks. Corelight built its first solution incorporating the powerful and widely-used open source framework that provides wide-ranging real-time understanding of the traffic on the network. Its first product, the Corelight Sensor, is an appliance that provides detailed information organized in ways to help users understand network traffic deeply and take action to stop and prevent cyber attacks. The company has been supported by an SBIR grant, and the Bro project was initially funded by the National Science Foundation (NSF) at the International Computer Science Institute (ICSI).
