ntopng is a web-based network traffic monitoring application designed to provide detailed visibility into network activity.
It collects and analyses network traffic, organising the results into information about hosts, connections, applications and protocols. Administrators access the monitoring interface through a web browser, where they can investigate current network activity and examine historical measurements.
ntopng uses deep packet inspection technology to identify application protocols and can collect information from network interfaces, mirrored traffic and external flow exporters.
The software is available in several editions. The Community edition is free and open source, while commercial editions provide additional monitoring, analysis and management capabilities.
ntopng is the maintained successor to the original ntop application. Its capabilities extend beyond simple bandwidth monitoring, making it suitable for network troubleshooting, traffic analysis and security investigations.
This is free and open source software.
