Last week we have attended Suricon 2024, the annual conference about Suricata and presented our work on how nDPI has been integrated with Suricata. At ntop we like to contribute to other open source projects we use and like, such as Suricata and Wireshark. One of the main limitations of Suricata is its inability to […]
Last week during SharkFest Europe 2024 we have presented what are network fingerprints and how they work. During the talk we (Luca and Ivan) have described how we have extended nDPI with support of network fingerprints, and how this work has been also integrated in Wireshark. We believe that fingerprints are an interesting technology that […]
Many users requested us a simple way to visualise hosts activity overtime. In essence have the ability to answer questions like: What hosts were active during the week-end When a host is using most of the network. What hosts were active when a certain event happened. This is what hosts activity monitor does. In the […]
Depending on the network topology and configuration, your monitoring tools can receive the same traffic multiple times. This problem is called data duplication. Duplication can happen at packet or flow level: Packet duplication The same packet is received multiple (usually twice) times, either one after the other, or within a short mount of time. Note […]
We continually strive to make the software configuration and management more flexible and easier for the users. To this end, we are excited to announce the launch of a new way of licensing the software feature: the centralised License Manager (LM). This tool simplifies software license management by dynamically allocating licenses to various application instances […]
ntopng is not typically classified as an Intrusion Detection System (IDS) in the traditional sense, but it does have some features that overlap with IDS functionalities. Let me explain the differences and how ntopng might serve a similar role: What is ntopng? ntopng is an open-source network traffic monitoring tool that provides visibility into network […]
In order to assist our community with 24/7 support, we have built an AI/LLM-based bot that has been trained on the ntop documentation (all products including ntopng, nProbe, nDPI…) and blog posts on this website. Currently this service is available in beta version and it is accessible using Discord on our ntop server (read here […]
In flow (sFlow/NetFlow/IPFIX) collection, nProbe acts as a “flow processor” for ntopng . nProbe is responsible for sending ntopng flows after they have been processed that includes Probe mode. nProbe captures network packets that are converted into flows that are then exported to ntopng. Collection mode. nProbe collects flows produced by a probe such as a […]
Today we report how ntopng has been used by Alabus AG to improve the corporate security (German version down this page). Enjoy ! PS. ntop users are very welcome to contact us reporting how they use ntop tools. ntop is used as a basis for analyzing the entire network traffic and it generates a very […]
Next year the ntop community will meet in Zürich, Switzerland for a two days event (training and conference) on May 7 and 8th. As already happened in the past, we want to meet our users and discuss with them what we have done and what are the future directions to take. This event will not […]
