nProbe 1.0 was introduced in 2002. After 20 years we are glad to introduce nProbe 10 that introduces several new features and improvements: Agent mode for process monitoring on Linux (eBPF) and Windows Implemented timeseries support for nProbe self-monitoring and sFlow-based counter timeseries Conversion of Amazon AWS VPC files into flows Export of flows towards […]
Introducing nDPI 4.4: Many New Protocols, Improvements and Cybersecurity Features
This is to introduce nDPI 4.4 that includes the development activities of the last six months. As with previous releases we are improving protocol support, automatic testing to harden the code for critical environments, and introducing new cybersecurity features for detecting risks and extracting metadata from protocols. Our idea is to make nDPI more user […]
HowTo Visualise ntopng Alerts in Kibana
ntopng can export both flows and alerts in Elastic according to the Elastic Common Schema (ECS) format. You can dump flows (not alerts) in Elastic starting ntopng with -F “es;<mapping type>;<idx name>;<es URL>;<http auth>”. For instance you can do ntopng -F “es;ntopng;ntopng-%%Y.%%m.%%d;http://localhost:9200/_bulk;” We do not advise to use Elastic as flow collector, as when the […]
HowTo Use nProbe To Create Traffic Timeseries in InfluxDB
One of the latest additions in nProbe, is the ability to create network traffic timeseries that will be stored in the popular InfluxDB database. This features allows nProbe users to create timeseries that can be depicted and integrated in Grafana dashboard for instance. Timeseries are dumped by means of two new nProbe command line options: […]

How to Configure Flow Risk Exclusions in nDPI and ntopng
Flow risks are the mechanism nDPI implements for detecting issues in network traffic whose theoretical design is documented in this paper Using Deep Packet Inspection in CyberTraffic Analysis we have written last year. While we are reworking the definition of risk exceptions in ntopng to make them fully configurable with a matter of clicks, you […]
Best Practices for Using ntop Tools on Containers
Many people use software containers to simplify application deployment. As you know ntop tools are also available on docker hub for quick deployment using Docker or other container management tools such as Portainer or Kubernetes. When using containers, there are a few things to keep in mind: Service Persistency ntopng relies on third party services […]
How ntopng monitors IEC 60870-5-104 traffic
Busy times for OT analysts. Last month the number of known OT (operational technology) malware increased from five to seven. First malware discovered is Industroyer2 which was caught in the Ukraine. As nowadays popular, security companies name the malware they discover. That is why for the second malware two names were assigned, Incontroller or Pipedream. […]
Registration for ntopConf 2022 (June 23-24) is now Open
This year the ntop community will meet in Milan, Italy on June 23-24. Conference will take place the first day, whereas the second day will be used for training. We’ll be talking about network traffic monitoring, cybersecurity, and discuss future roadmap items. It is a good chance to get together after pandemic restrictions, as well […]
HowTo Use TLS for Securing Flow Export/Collection
One of the main limitations of flow-based protocols such as IPFIX and NetFlow is that the traffic is sent in cleartext. This means that it can be observed in transit and that it is pretty simple to send fake flow packets that can then pollute the collected information. As of today, unencrypted protocols need to […]
