Starting with nDPI 4.10, we have introduced a new feature called First Packet Classification (FPC). Goal of this technique is to address one problem of DPI that detects a protocol only when traffic has been dissected. This means that for TLS you need a few packets (usually between 5 and 10) for protocol dissection, as […]
Announcing ntop Professional Training: October 2024
ntop tools range from packet capture, traffic analysis and processing, and sometimes it is not easy to keep up on product updates as well master all the tools. This has been the driving force for organising ntop professional training. This is to announce that in October we have scheduled the next ntop Professional Training session. […]
How Historical Flows Replay Works
ntop users who have enabled ClickHouse, know that they can search/aggregate/export historical flows and create customized reports. However, in the past months some of our users were uncomfortable of this approach as they preferred to seamlessly analyze historical as live data with the full power of ntopng. In the latest ntopng version we have added […]

This is to announce the release of nDPI 4.10. This release adds many improvements and new detected protocols. For this reason future releases will be scheduled more often on a 4 or 6 months (hard) basis in order to provide you constant updates on a predictable timeframe, Beside adding many dissectors, this release paves the […]
Positioning ntopng vs nProbe for Traffic Analysis
Recently we have compared the use of nDPI in a realtime application (ntopng) and a near-realtime (nProbe). We have captured a short pcap with some mixed traffic and analysed it with both applications. The expectation was to find comparable results between the two applications, but this happened only partially. This blog posts explains the main […]
HowTo Extend ntopng with new Host/Flow Checks and Alerts
ntopng can be easily extended with new host/flow checks and alerts. They are developed in C++ with a few Lua files used by the UI to configure the check and format the emitted alerts. In order to introduce you to thir development, we have written a short guide that shows you step-by-step how to develop […]
HowTo Export ntopng Alarms to Checkmk Event Console
Checkmk is a popular platform for monitoring IT infrastructure. ntopng has been integrated in Checkmk some time ago, enabling users to provide traffic visibility in additional to classic bytes/packets metrics. As ntopng is able to produce traffic alerts that, we have decided to extend ntopng in order to export alert information towards Checkmk event console […]
