We’re excited to announce the release of nDPI 4.14, a maintenance release that also includes some cool new protocol dissectors and fixes. As you know, maintaining a DPI library is no easy task, and this release is no exception. We’ve worked hard to enhance existing dissectors, making them more robust and efficient. We’ve also cleaned […]
Using Network Fingerprints Beyond Cybersecurity
Last week ntop has been invited to give a talk at neacademy in Napoli, Italy. The topic was network fingerprints and nDPI. Network fingerprints such as JA4 have been made popular by cybersecurity that uses them to spot (with limited false positives) malware and use them to find traffic pattern similarities. During the talk, we […]
AI-Driven Networks: A ML Solution for 5G Networks based on nProbe
In this contributed post the Universidade de Aveiro, Instituto de Telecomunicações, Portugal, explains how nProbe has be successfully used in 5G networks. Introduction As networks evolve to meet the demands of modern connectivity, the need for intelligent traffic monitoring and anomaly detection becomes increasingly critical. In the context of 5G networks, where high-speed data […]
Introducing Network Quality Measurement (QoE) in ntop Tools
Quality of Experience (QoE) measures how satisfied users are with a network service based on their subjective perception. Unlike Quality of Service (QoS), which focuses on technical metrics (e.g., latency, jitter, packet loss), QoE evaluates the actual end-user experience—such as video streaming smoothness, call clarity, or web browsing responsiveness. QoE is important from various points […]
Announcing ntop Professional Training at ntop Conference (PacketFest) and June 2025
PacketFest will talk place in Zurich, Switzerland, on May 8-9 and it will be the event where the ntop and wireshark communities meet. On May 7th we organize for the ntop community an in-presence training session where we will show the latest news about ntop tools and teach how to master them. The training is […]
HowTo Use Host Policy to Detect Misbehaving Hosts
ntopng has several ways to spot unusual traffic patterns, like: Checking if a device is behaving strangely. Sending alerts when a threshold is reached. Looking for changes in traffic metrics (like how much traffic is coming from a particular host). Seeing if host services change. To make these checks even better, ntopng added a new […]
When Traffic Obfuscation Falls Short: nDPI vs NordWhisper NordVPN
In recent years, numerous virtual private networks (VPNs) have been introduced to the market. Some of these VPNs are standalone applications, while others are integrated into web browsers or other network applications. All of these VPNs promise users a private browsing experience by preventing users from being tracked and observed, particularly on public hotspots. Popular […]
9 Reasons You Should Use Ntopng on Your Raspberry Pi
This XDA article has published an interesting article about ntopng on rPI. In particular: Learn and experiment with networking It’s a low-power solution It integrates with other network tools (e.g. Zabbix or Nagios) Optimize your home network traffic Analyze historical network data Manage bandwidth and QoS settings Capture and analyze network packets (via nDPI) Detect […]
Using ntopng as Generic Flow Collector (log files, firewall events, MQTT…)
Most users of our community use ntopng as flow (sFlow/NetFlow/IPFIX) collector with ntop tools such as nProbe or nProbe Cento. From time to time we receive inquiries about using it as generic flow collector for instance reading connection information from the firewall, log files/syslog, MQTT, or cloud formats. This blog post shows you howto do […]
Using ntopng for Teaching Network Monitoring and Administration
ntop believes in education, research, and no-profit and for this reason ntop tools have been them offered free of charge. Today we’re pleased to hear how they have helped young students to monitor and administer networks. Enjoy ! Introduction When teaching network monitoring and administration at the University of Applied Sciences in Fribourg […]
