Now You Can Really Know your Network
FlowViewer is an open-source solution for the visualization of network traffic through the capture and analysis of netflow data. Because it is open-source and most network devices already provide netflow data, FlowViewer provides you with a comprehensive network traffic solution essentially for free.
FlowViewer sits on top of Carnegie Mellon's robust, high-performance SiLK netflow data capture-analysis software and consists of three major component tools: FlowViewer, FlowGrapher and FlowMonitor (see below.)
FlowViewer reveals the who, what, where, when and how of traffic over your network. Multiple dashboards allow your different organizations (e.g., Security, Operations, etc.) to focus on proprietary concerns on a live operational basis.
With the CAPEX savings FlowViewer offers, you can consider our Service Options which include installation support and training to bring your network organization up to speed quickly.
