Dedicated to Bro for over 20 years.

Corelight is dedicated to making networks safer with Bro.

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