Noction Flow Analyzer

What Noction Flow Analyzer is

Noction Flow Analyzer (NFA) collects and presents network traffic data for monitoring, reporting, capacity planning, and analysis. It accepts NetFlow, J-Flow, sFlow, IPFIX, and NetStream flow data, alongside SNMP and BGP. Data Explorer lets users filter flow data, and dashboards offer built-in views or visualizations users create. For DDoS mitigation, NFA can detect abnormal flow patterns and use BGP FlowSpec to drop, throttle, or redirect attack traffic, with automatic or moderated mitigation. Users can define alert rules and receive notifications through email, webhooks, Slack, or Telegram. NFA is designed for routers, switches, and firewalls that export supported formats, and has been tested with devices from Cisco, Juniper, Huawei, Brocade, Alcatel, Vyatta, Mikrotik, Arista, and ZTE. It runs on x86_64 with RHEL 8 or 9, or Ubuntu 22.04 or 24.04 LTS; a dedicated server is recommended, and a suitably specified VM is supported. Default level 3 aggregated data is retained for 400 days. The license covers up to 10,000 flows per second, with custom pricing above that. Monthly and yearly licenses include unlimited devices, interfaces, sites, and users, plus free 24/7 support. A 30-day trial is available, but there is no free plan.

Who it suits

NFA suits network teams that need to inspect flow data, monitor bandwidth, plan capacity, or analyze traffic conversations across supported network devices. It may also fit teams seeking flow-based DDoS mitigation and configurable alerts, provided they can run it on a supported Linux server or VM.

Limits

The regular NFA license covers up to 10,000 flows per second; higher capacity has custom pricing. The BGP add-on is optional and priced separately.

Getting started

1. Open the Noction Flow Analyzer website.
2. Choose a 30-day trial or a monthly or yearly NFA License.
3. Prepare an x86_64 server or suitably specified VM with RHEL 8 or 9, or Ubuntu 22.04 or 24.04 LTS.
4. Connect routers, switches, or firewalls that export supported flow formats.
5. Add the optional BGP add-on if you need detailed BGP data and in-depth BGP queries.

Verdict

Choose Noction Flow Analyzer if you need flow-based network monitoring, traffic analysis, alerting, and BGP FlowSpec mitigation in one deployment. Look elsewhere if you need a free plan or your flow volume exceeds 10,000 per second without custom pricing.
