Zeek Community

Dedicated to Zeek for over 20 years.

Corelight is dedicated to making networks safer with Zeek.

Not only did the founders and engineers at Corelight build and extend Zeek over the last two decades, we continue to dedicate significant resources toward improving the platform. The rich structured and correlated data produced by Zeek is the result of hundreds of person-years of work by a dedicated group of developers and contributors, funded in part by the National Science Foundation and ICSI.
