Last week we have talked at ITNOG6 where we presented a report of the lessons learnt while monitoring ISP and service providers networks. This work is the result of one year of activities carried on with some of our users who provided feedback and new ideas. In summary we concluded that cybersecurity is a hot […]
HowTo Select the Right Network Adapter for Traffic Monitoring and Cybersecurity
Since the introduction of PF_RING ZC drivers for Mellanox/NVIDIA, and the new family of Intel E810 adapters, the activity of selecting the best, cost-effective adapter, based on the use case and the performance we need to achieve, has become more complicated. Let’s try to shed some light. Intel Adapters Most commodity adapters, including Intel and […]
Introduced RHEL/RockyLinux 9 support (and new GPG Package Signing Keys)
This is to announce the availability of ntop packages for RedHat EL9 / RockyLinux 9 at packages.ntop.org. This has forced us to change many things in the way we build packages due to the deprecation of the SHA-1 algorithm. Because of this we had to modify the GPG signing keys used to sign the ntop […]
Welcome to ntopng 5.4: Enhanced Traffic Analysis and Cybersecurity
The previous stable release introduced a new persistency layer based on ClickHouse, paving the way for a more flexible yet fast historical data analysis, with its ability to store billion of records (alerts and flows) with limited disk space and very low query time. This new 5.4 release introduces many enhancements in the historical data analysis […]

Initially designed as a maintenance release, 5.2 brings many improvements in its processing engine with over 3’000 code commits. The main goal is to enhance application scalability by optimising memory and CPU usage, while introducing a new persistency layer based on ClickHouse that has replaced nIndex a home-grown high-performance indexing system that we introduced years […]
Introducing nDPI 4.2: More Protocols and Robustness with -80% Memory
This is to announce the availability of nDPI 4.2 stable that brings several improvements and a reduced per-flow memory footprint (about -80% with respect to 4.0). We have continued to improve the DPI engine adding richer protocol metadata, as well as adding support for many platforms. The continuous integration toolchain along with fuzzy-testing allowed us […]
Historical Traffic Analysis at Scale: Using ClickHouse with ntopng
Last year we have announced the integration of ClickHouse, an open source high-speed database, with nProbe for high-speed flow collection and storage. Years before we have created nIndex, a columnar data indexing system that we have integrated in ntopng, but that was just an index and not a “real” database. We have selected ClickHouse for […]
