netflow analyzer trafficIn our previous article we explained how a Netflow Analyzer can help you gain visibility into your user traffic, application traffic and data flows while at the same time analyze traffic patterns, detect unusual traffic, verify bandwidth availability, detect Quality of Service (QoS) problems and a lot more.

In this article we will introduce Network Analyzer - a bandwidth and traffic analysis tool that helps you monitor the bandwidth utilization in your network and analyze the who, when, what of your network traffic. It uses flow technology to give you real time visibility into your network and supports all major flow formats such us netflow, sflow, jflow, IPFIX, and appflow.

Network Analyzer helps you to drill down into interface level details to discover traffic patterns and monitor device performance, recognize and classify Non-Standard Apps that hog your network bandwidth, and detect security threats. Using a network bandwidth monitoring tool like NetFlow Analyzer allows you to monitor all these critical parameters in real-time.
