README.md

Community Edition

It's 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.

Installation

Supported packet capture engines

  • NetFlow v5, v9, v9 Lite
  • IPFIX
  • sFlow v5
  • PCAP
  • AF_PACKET (recommended)
  • AF_XDP (XDP based capture)
  • Netmap (deprecated, still supported only for FreeBSD)
  • PF_RING / PF_RING ZC (deprecated, available only for CentOS 6 in 1.2.0)

Features

  • Detects DoS/DDoS in as little as 1-2 seconds
  • Scales up to terabits on single server (sFlow, Netflow, IPFIX) or to 40G + in mirror mode
  • Trigger block/notify script if an IP exceeds defined thresholds for packets/bytes/flows per second
  • Thresholds can be configured per-subnet basis with the hostgroups feature
  • Email notifications about detected attack
  • Complete IPv6 support
  • Prometheus support: system metrics and total traffic counters
  • Flow and packet export to Kafka in JSON and Protobuf format
  • Announce blocked IPs via BGP to routers with ExaBGP or GoBGP (recommended)
  • Full integration with Clickhouse InfluxDB and Graphite
  • API
  • Redis integration
  • MongoDB protocol support compatible with native MongoDB and FerretDB
  • VLAN untagging in mirror and sFlow modes
  • Capture attack fingerprints in PCAP format

We track multiple platform and environment-specific metrics to understand ways how our product is being used and prioritise development accordingly.
