What are Network Sniffing Tools?


Network sniffing tools allow you to analyze your network traffic by intercepting data as it is transmitted over your network. The collected data can be used to gain an overview of your network performance. Network sniffers can also help identify network related problems. Other possible uses include data acquisition, connection and interface testing, diagnostic analysis or identifying Shadow IT.

The free network sniffer included within PRTG Network Monitor detects all data activity in your network, as well as application usage of your system's  ports.  All the data that is being sent and received through your network can be easily monitored with PRTG. With PRTG and its included network sniffer, there is no need for additional network monitoring software. This advanced monitoring utility can capture, view, log, and analyze network data.

 

You can use the network sniffer for data acquisition, connection & interface testing, diagnostic analysis, packet analyzer, identifying Shadow IT and more.

PRTG Network Monitor features a flexible system of fully configurable filters and reports that can be used to capture only the specific traffic patterns and network data you wish to analyze.

In addition, PRTG's network sniffer supports a wide selection of events, methods and properties.

If you're looking for a professional tool that will simplify the tasks of monitoring and managing your network's traffic data, PRTG Network Monitor is your solution. Offering both a completely free, basic edition and expanded commercial editions, this free network sniffer is the right choice for all your network monitoring & analysis needs.
