FastNetMon Community Edition is a high-performance DDoS detection sensor that analyzes traffic from NetFlow, IPFIX, sFlow, AF_PACKET, and other capture engines. It detects hosts sending or receiving abnormal traffic volumes within seconds and can notify operators, run scripts, or announce blocked IPs via BGP.
Use cases
- detect ddos attacks on my network in real time
- collect and analyze netflow and sflow traffic data
- automatically block attacking ips via bgp announcements
- monitor traffic thresholds per subnet with alerts
- export flow data to kafka or prometheus
- set up a ddos sensor for an isp network
When to choose
- you need fast (1-2 second) DDoS detection at terabit scale from flow data or port mirrors
- you want automated mitigation hooks like BGP blackholing via ExaBGP or custom scripts
- you run a multi-vendor network (Cisco, Juniper, MikroTik) exporting NetFlow/sFlow/IPFIX
When to avoid
- you need full-featured mitigation, GUI, and support - the Advanced commercial edition may fit better
- you only need simple bandwidth graphing rather than attack detection
- you cannot run a dedicated Linux sensor or collector
