Promoting Traffic Visibility: from Application Protocols to Traffic Categories in nDPI and ntopng

Posted · Add Comment

Often we receive emails asking question like: “how many protocols nDPI supports?”, “how do you position nDPI against commercial DPI toolkit A, B, C?”. Although these questions are reasonable, they do not grasp the significance of DPI. For years commercial toolkits have run the race for protocols: I have 200 protocols, I have 1000 protocols, […]

Securing ntopng with SSL and Let’s Encrypt

As you know ntopng web interface supports both HTTP (default) and HTTPS. The reason why ntopng does not default to HTTPS is because we provide self-signed certificates that web browsers dislike.

Introducing per-Second Measurements in nProbe Flow Exports

Posted · Add Comment

The need to perform on-time and per-second traffic measurements clashes with protocols such as NetFlow where all counters are cumulative with respect to the flow lifetime. So if you have a flow that lasted 2 minutes and moved X bytes, you have no clue what was the throughput of this flow across the 2 minutes. […]
