Community Edition

FastNetMon - A high-performance DDoS detector/sensor built on top of multiple packet capture engines: NetFlow, IPFIX, sFlow, AF_PACKET (port mirror).

What do we do?

We detect hosts in the deployed network sending or receiving large volumes of traffic, packets/bytes/flows per second and perform a configurable action to handle that event. These configurable actions include notifying you, calling script or making BGP announcements.
