Even at the NCSA, with our strong use of Bro, we record and utilize netflows. Part of it is because we have tools and infrastructure in place to quickly search NetFlows. Part of it is because all our routers give us NetFlows, giving us some views of internal traffic that Bro sensors will never see.

It really isn't an either-or case for us.

> I probably screwed up by titling the thread Bro *versus* NetFlow... I was mainly curious if anyone had managed to do away with NetFlow analysis through pervasive use of Bro. I didn't think that would likely be the case.
