About ManageEngine NetFlow Analyzer

ManageEngine NetFlow Analyzer is a web-based bandwidth monitoring tool that collects NetFlow data exported from routing devices, and uses it to analyze and report on IP traffic across the network. With instant reports on top applications, protocols, conversations, and hosts, NetFlow Analyzer gives you valuable insight into bandwidth usage in your enterprise without the complexity and expense involved in a traditional WAN analysis setup.
