ManageEngine NetFlow Analyzer is a web-based bandwidth monitoring tool that collects, correlates, and analyzes NetFlow version 5,7,9 exports to show you what applications are using bandwidth, who is using them, and for how long. View in-depth bandwidth reports across your WAN and LAN without having to deploy expensive hardware probes.

Recognize most enterprise applications and see how traffic flows across your network. NetFlow Analyzer uses Cisco's NBAR technology and can analyze and identify application traffic in real time. NetFlow Analyzer supports Cisco CBQoS, which helps in monitoring class based pre policy, post policy usage, drops and queuing. It also generates usage based billing, which helps you keep a tab on the bandwidth usage and thus adding tremendous value to your business.
