Contribute to the Herd

We are all safer when we work together. Here are a few ways you can help us grow the herd and make the internet safer for everyone.

Create scenarios

A scenario is a configuration file which allows modeling against behaviors from events captured in log files. These events are measured, compared, and correlated to determine a framework outside of which any activity will be considered suspicious. 

Do you have a specific scenario you want protection against? Help the herd and build it!
