NetVizura NetFlow Analyzer

What NetVizura NetFlow Analyzer is

NetVizura NetFlow Analyzer helps network administrators examine traffic by device, interface, subnet, traffic segment, and end user. It accepts NetFlow v5 and v9, NSEL, IPFIX, and sFlow exports. The vendor names Cisco, Juniper, and HP among supported vendors and says devices that export supported flow protocols can be used. Analysis spans hosts, conversations, services, protocols, QoS markers, and autonomous systems. Administrators can define Traffic Patterns using attributes such as routers, interfaces, service ports, autonomous system, QoS, protocol, and next hop.

For investigations, the product provides charts, tables, drill-down views, and a raw data archive for reviewing older traffic anomalies. Throughput and volume thresholds can trigger alarms, with email notifications and a central alarm overview. Traffic reports can be exported and scheduled for email delivery, including to recipients outside the department. The software is self-hosted, with downloads listed for Linux and Windows; Linux options include Debian/Ubuntu and CentOS packages, plus a Linux ISO/VMware image. The 30-day trial includes NetFlow Analyzer, EventLog Analyzer, and MIB Browser. Trial use is limited to 500 flows per second and five NetFlow exporters. Paid perpetual and subscription licences are based on network flow rate, with prices available on request.

Who it suits

NetVizura NetFlow Analyzer suits network administrators and teams monitoring bandwidth, investigating traffic, planning capacity, or working on network security. It fits organisations that can deploy a self-hosted tool and collect flow exports from devices using supported protocols.

Limits

The free trial runs for 30 days from installation and allows up to 500 flows per second and five NetFlow exporters. The perpetual and subscription licences are based on network flow rate and have no limits on routers, interfaces, hosts, or users.

Getting started

1. Visit the NetVizura NetFlow Analyzer website.
2. Choose a listed Linux or Windows download for your environment.
3. Install the 30-day trial, which includes NetFlow Analyzer, EventLog Analyzer, and MIB Browser.
4. Connect flow-exporting devices using a supported protocol; free probes such as Softflowd can generate flow data when devices cannot export it themselves.
5. Use a trial with up to 500 flows per second and five NetFlow exporters.
6. For ongoing use, request pricing for a perpetual or subscription licence based on network flow rate.

Verdict

Choose NetVizura NetFlow Analyzer if your team needs detailed flow analysis, historical investigation, threshold alarms, and scheduled reports in a self-hosted deployment. The trial lets you assess three included modules for 30 days, within its flow-rate and exporter limits. Look elsewhere if you need a hosted deployment or a paid plan with a published price.
