Sonar Software's new On-Premise NetFlow Receiver lets ISPs track per-account customer data usage with precision and control, right from inside their own network. By mapping traffic flows at the source, it keeps usage tracking accurate, scalable, and resilient for billing and network operations.

We're excited to announce this powerful new way to track customer data usage. The On-Premise NetFlow Receiver gives you deeper visibility into traffic flows and ensures usage tracking stays accurate and resilient.

With this update, you can:

Gain clearer, more reliable usage insights - See per-account traffic data mapped at the source for accurate reporting and billing.

Control scalability on your terms - Deploy the receiver on hardware sized to your traffic demands, avoiding cloud-side bottlenecks.

Reduce dropped data and inaccuracies - Shorter network paths mean fewer dropped packets and tighter data consistency.

Stay resilient through outages - Usage summaries queue automatically during connectivity issues, keeping your reporting intact.

How the On-Premise NetFlow Receiver works

Install the NetFlow receiver on your own hardware inside your network perimeter.

Point your routers to send NetFlow data directly to your on-premise receiver.

The receiver ingests and maps flows to the correct customer accounts automatically - no separate mapping syncs required.

Usage summaries transmit to Sonar every five minutes over periodic TCP bundles, ensuring accurate and timely reporting.

Running the receiver locally means your data stays closer to home - and under your control - leading to faster, more dependable performance. If you've been holding off on NetFlow due to scaling concerns or accuracy limitations, this is the upgrade designed with your feedback in mind.
