We reviewed the available free bandwidth monitoring software and analyzed the options based on the following criteria:. Their Real-Time NetFlow Traffic Analyzer provides useful data about bandwidth for devices that support NetFlow; we discussed this tool in an earlier post on the best free NetFlow analyzers and collectors.

It uses SNMP to poll multiple network interfaces in real-time for their traffic statistics and visually displays the status of a chosen interface graphically. Selecting one of the interfaces provides you with a graphical display of bandwidth usage on that interface.

You can set per-interface thresholds so that the graph displays an alert when usage exceeds your chosen limits. Another option for bandwidth monitoring that is offered by SolarWinds is the ipMonitor. This is not a free tool, but you can try it on a day free trial. This is a specialist tool that monitors network usage, servers, and applications. It keeps you aware of all network performance metrics, including uptime availability, internet service quality, and network capacity.

This monitor works on real-time network data including alerts and reporting functions, and it will help you head off capacity-related system failure. Bundled with a free network analyzer, you can see traffic by conversation, app, domain, and endpoint.

The free version is limited to sensors after the first month; since a sensor is an individual data stream, each device will typically require several sensors.

This is where VPN monitoring comes into play. VPN monitoring is the process of keeping an eye on critical metrics to maintain the integrity of the VPN connection and ensure its robustness against attacks.

Additionally, VPN monitoring ensures that sensitive data gets transmitted across VPN tunnels without being exploited by intruders. Ineffective VPN monitoring, or none at all, could lead to unauthorized access into private networks, paving the way for cyberattacks and data theft. Moreover, failure to address impending irregularities in VPN tunnels can lead to suspended connections, which in turn could affect the functioning and productivity of the business.
