ntopng - Web-based Network Monitoring

ntopng is the next generation version of the original ntop, a network traffic probe that monitors network usage. ntopng is based on libpcap/PF_RING and it has been written in a portable way in order to virtually run on every Unix platform, MacOS and on Windows as well.

ntopng Community

In this video we briefly introduce the main features of ntopng community. We show how to monitor network activity with hosts and flows, how to actively monitor hosts and services, and a flexible way to emit alerts.

In this video we look at how ntopng can be used to perform behavioral traffic analyses, to uncover suspicious or unwanted network activities.

Here we look at how ntopng can be used also to actively monitor hosts and services, to timely react to potential outages and security risks.
