Features of the Fl0wer platform

What you can do with it:


  • Understand what’s happening on your networks in near-realtime*, with full IPv4 and IPv6 support. See last N network flows (Network State Table).
  • Track all your network traffic from all your view-points (Netflow Exporters). Get real network visibility over time. Improve your BYOD or IoT security.
  • Use the included NPAR engine (Network Probabilistic Application Recognition) to classify all IPv4 and IPv6 traffic in near-realtime with a precision > 90%.
  • GeoReference your traffic using advanced MaxMind databases (available separately from MaxMind ).
  • Check near-realtime* usage of Social Networks or other Internet/Intranet Applications.
  • Detect near-realtime* top-talkers, most used protocols, TOR & P2P usage, most used subnets and more.
  • See instantly relationships between IP Addresses (who talks to who).
  • Respect your user/customer privacy: no user-contents are analyzed since only the flow metadata is provided as input.
  • Use it as a unique tool to help designing packet-filtering rules in existing networks.
  • Use it as a unique tool to help network or cloud migrations.
  • Let it build a Flow Matrix to match or create your packet-filtering rules.


  • Discovery of critical devices in your network: Routers, Storage, Web and Mail.
  • Use Network snapshots to take an instant view of your network status. Simple, fast, portable, shareable.
  • Export your data to anything you want (JSON, CSV, Oracle, SQLite, etc.).
  • Petabytes of data ? Use JSON or CSV to feed your favourite Big Data Number Cruncher or SIEM.
  • Got some brilliant ideas ? Write your own tool using the JSON API or, if not possible, let's talk about it !


  • Use active, user-customizable, action scripts for every flow/template with the integrated LUA Engine. Detect near-realtime* and react immediately if certain types of traffic are matched. Start tracking data exfiltrations.
  • Use Traffic Rules for consolidated actions to do on known traffic patterns: detect near-realtime* and alert if certail types of traffic are matched.

Open Data & Tools

  • Open Source CLI Tools and GUI Application, JSON API, with full C & Python 3 sources and examples.
  • Open Source and scalable binary data format
  • Open Source JSON & CSV data formats for easy integration with your favourite tools.
  • Pre-built clients are provided for Linux, Windows and Mac OSX.
  • Proven & Secure client-server model with TLS 1.2/AES-256 strong encryption, with full IPv6 support, for apps & data.


  • Field-tested with support for Cisco, Juniper, Palo Alto, Mikrotik, Ubiquiti, Fortinet, Huawei, Checkpoint GAIA, Sophos UTM, pfSense, opnSense, Watchguard, Stormshield, OpenVSwitch, VMWARE ESX & NSX Distributed VSwitch, Citrix XenServer, SoftFlowd, etc.
  • Based on proven Industry & Open standards: Netflow V1/V5/V9/IPFIX.
  • Available on Linux Debian/Ubuntu and RedHat/CentOS.
  • Oracle Solaris, IBM AIX, NetBSD and other ports are available on demand.
  • High performance (more than 200000 FPS on a dual Intel X5670 Xeon acting as NPAR collector only).
  • Scalable software (runs from an APU2 to large X64 to a multicore Sun SPARC T5220 and more).
  • Very low-cost, with an astonishing TCO against competition products.
  • No software or license limits, hardware is the limit.
