In their own words
Noction Flow Analyzer
Noction Flow Analyzer collects, stores, and presents network-traffic data for monitoring, reporting, capacity planning, and analysis. It supports NetFlow, J-Flow, sFlow, IPFIX, NetStream, SNMP, and BGP. Data Explorer filters flow data, while dashboards provide built-in or user-created visualizations. The software can detect abnormal flow patterns and use BGP FlowSpec to drop, throttle, or redirect attack traffic automatically or with moderation. Alert notifications can go by email, webhook, Slack, or Telegram. NFA runs on x86_64 with RHEL 8 or 9, or Ubuntu 22.04 or 24.04 LTS; a dedicated server is recommended, though a suitably specified virtual machine is supported. Level 3 aggregation is retained for 400 days. The monthly NFA license costs $299 a month and the yearly license $2,990 a year, each covering up to 10,000 flows per second, unlimited devices, interfaces, sites, and users, plus free 24/7 support.
