We are very excited to see all the interest that Bro has been
generating recently, with many new deployments across networks of all
sizes and people working to interface the system to their environments
and hardware. Occasionally, however, we also notice a bit of confusion
about Bro’s licensing in terms of what exactly it permits and where it
imposes constraints. To help clarify that, we have have created a new
Licensing section in our FAQ,
and a separate page with guidelines for using the Bro marks.
Here’s the short version:
- Bro’s source code is, and will remain, open-source under the
very permissive BSD license. The license allows for pretty much
unrestricted distribution and use. Specifically, you are free to
deploy any or all of the code in commercial products. You don’t
even need to tell us about it if you’d rather not. - All documentation and web page content is licensed under a
Creative Commons NonCommercial license. This
means that you can use, share, and adapt the material as long as
you attribute the Bro Project as the source and do not use it
for any commercial purposes. - Finally, we reserve all rights to the Bro name and logo. In many
cases it will be fine for you to use our marks but we ask for a chance
to review your case. In particular, we consider it important that we
avoid any confusion on what the name "Bro" refers to. We have a
simple rule of thumb for that: if it’s called "Bro", it must be
our "Bro" as found on www.bro.org. You
are free to derive your own versions from our code base, but you
can’t call it "Bro" unless we have signed off on your use. We
believe that this is a fair constraint in the interest of Bro’s
users, and indeed not unusual in the open-source world.
