    NetVizura NetFlow Analyzer
    NetFlow Analyzer is an easy solution for net admins to better understand bandwidth consumption, traffic trends, applications, hosts and traffic anomalies, by visualising the traffic by network devices, interfaces and subnets, traffic segments and end users. NetFlow Analyzer utilizes Cisco® NetFlow, IPFIX, NSEL, sFlow and compatible netflow-like protocols to help net admins with bandwidth monitoring, network traffic investigation, analyses and reporting. This way, companies can optimise networks and applications, plan network expansion, minimize time spent on troubleshooting and diagnostics, and improve security. NetVizura allows you to define custom traffic to be monitored based on IP subnets and traffic characteristics like protocol and service used. Monitor specific traffic for each organisational unit in your network such as departments, remote sites and collections of regional offices by identifying them with IP subnets.
