Please understand that this post is not intended to be antagonistic in any
way, but I remember Bivio claiming to (briefly) natively support Bro (with a
custom and/or pre-compiled and/or optimized-for-hardware version; IIRC it
was called "Brooklyn").

Policy prevents me from publicly endorsing any product/service/vendor
(etc..). I will say, though, that your appliances perform appx. as well as
the sales documents claim they do, in real-world use.

Which brings me to my question: is there a resurgence in Bro interest within
your company? Or are you simply stating above that you have a platform which
can run a NIDS stack at high speeds?

Public or private reply is O.K.
