Nfsight: Netflow-based Network Awareness Tool


Nfsight is a Netflow processing and visualization application designed to offer a comprehensive network awareness solution. It is developed as a Nfsen plugin to construct bidirectional flows out of the unidirectional netflow flows. Nfsight leverages these bidirectional flows to provide client/server identification and intrusion detection capabilities.

Nfsight is a research project jointly developed at the University of Maryland and AT&T Labs Research.
