f2ff9502f5dc2b23c74162a79247bc1573fccd90ac78ca8ecdbcb3d0bea1c968Zeek is a powerful network analysis framework that is much different from the typical IDS you may know. While focusing on network security monitoring, Zeek provides a comprehensive platform for more general network traffic analysis as well. Well grounded in more than 15 years of research, Zeek has successfully bridged the traditional gap between academia and operations since its inception. Today, it is relied upon operationally in particular by many scientific environments for securing their cyber-infrastructure. Zeek's user community includes major universities, research labs, supercomputing centers, and open-science communities.
