Bro (https://www.bro.org) is a network monitoring and protocol analysis framework that has been in development for roughly 15 years. Its name is a reference to "Big Brother" due to its ability to provide visibility into network traffic. The project also got a MOSS grant for $200K today. (http://blog.bro.org/2015/12/bro-receives-200k-grant-from-moz...) An employee from Mozilla gave a talk at BroCon this year describing how they use Bro.
