NTOPNG

High-Speed Web-based Traffic Analysis and Flow Collection

Ntopng (new generation) it's the evolution of ntop, a probe for analysis of network traffic that shows the network usage, similar to what can be done through the popular top Unix commands. ntop is based on libpcap libraries and was written so as to be "portable" in order to virtually run on every Unix or Win32 platform.

The ntop users can use a web browser to navigate through the traffic information provided by ntop (which effectively acts as a web server) and get a dump of the network status. In the latter case, ntop can be seen as a simple RMON agent with an embedded web interface.

PACKET CAPTURE

Wire-speed packet capture and transmission using commodity hardware with PF_RING. Zero-Copy packet distribution across threads, applications, Virtual Machines. Libpcap support for seamless integration with legacy applications.

TRAFFIC RECORDING

100 Gbit lossless network traffic recording with n2disk. Industry standard PCAP file format. Layer-7 on-the-fly indexing to quickly retrieve interesting packets using fast-BPF and time interval. Precise traffic replay with disk2n.

NPROBE

nProbe: extensible NetFlow v5/v9/IPFIX probe with plugins support for L7 content inspection. nProbe Cento: up to 100 Gbit NetFlow, traffic classification, and packet shunting for IDS and packet-to-disk acceleration.

TRAFFIC ANLYSIS

High-speed web-based traffic analysis and flow collection using ntopng. Persistent traffic statistics in RRD format. Full historical data to ClickHouse and big data systems. Layer 7 analysis based on nDPI, an Open Source DPI framework.

Why is ntop Different?

The industry is full of hardware companies who bundle their products with open-source products, just to offer a sale argument for their products. Or software companies who depend on other (either hardware or software companies) for running their applications. ntop does not belong to any of these categories. We are not hardware-vendor dependent, and our software does not rely on third-party companies who might impose high license fee or decide to send us (and thus our users) out of business.

We are developing both software that better exploit commodity hardware (so we’re not vendor locked) and that runs on the operating system kernel, and monitoring applications. We control the whole lifecycle, optimize every single bit, and provide you support for all our components, as we have developed them and nobody knows them better than us. This is quite rare on this market, and thus we have the ability to optimize the software for the hardware we use, and create better products. Very few other companies such as Ferrari, Ducati or Apple can do that (we’re small but we believe we belong to this club).

This is why people say: ntop means open-source from the source.
