Network Traffic Analysis through a Cisco ASA with NetFlow

Yes, you can use NetFlow to monitor traffic and bandwidth usage on an ASA.
One of the primary uses for NetFlow on a Cisco ASA is as a transport protocol for security events. But if you are using the right NetFlow Analysis tool, you can also analyze traffic using NetFlow sent from the Cisco ASA.
This is really important as I have seen many companies that have remote sites that are connected with a Cisco ASA, but had no devices behind the ASA’s that supported NetFlow. This meant that they couldn’t leverage NetFlow to analyze traffic.
