Review on AlgoSec BusinessFlow by Maurice Stavros

I like that it can run in parallel with other network operations allowing for more complete security visibility, as well as giving you an accurate picture if current state vs what's being monitored by your firewall/proxy appliances.

It requires some learning curve but once you have it setup correctly, there are really only two things missing from this product - better support (we've had several problems) & more features! If you're looking for something that will provide good baseline data about where your users traffic flows between various points within our internal IT networks look no further than algosec business flow. We use their products primarily to see how much access certain sites get via different IP addresses or locations within the LANs we control. As such we get great benefit from knowing exactly which ports need patching when working out new server builds etc.
