What is Zeek?

Zeek (formerly known as Bro) is a powerful network analysis framework. It provides a comprehensive platform for network security monitoring, enabling real-time analysis of network traffic. Zeek is often used for intrusion detection, anomaly detection, and security research, and is valued for its ability to provide deep insights into network behavior beyond simple signature-based detection. It parses network traffic and uses event-based language for customized analysis.
