NetFlow DDoS Protection is a paid ISPBills add-on with a 14-day free trial and tiered monthly pricing.

See the overview for what NetFlow does, or the setup guide to start exporting flows.

Pricing Model

NetFlow is sold as a monthly add-on with three capacity tiers:

Tier Price (BDT / month)
10Gbps ৳12,000
40Gbps ৳25,000
100Gbps ৳55,000

NetFlow availability depends on add-on visibility for your account. If it is missing, contact your super_admin or ISPBills support.

Start the 14-Day Free Trial

A 14-day free trial is available inside the ISPbills admin panel.

  1. Open Monitoring → NetFlow.
  2. Select Start 14-Day Free Trial.
  3. Enable the collector and configure your exporters.
Trial item Behaviour
Length 14 days
Feature access Full NetFlow dashboard, sources, live flows and reports
Billing during trial No NetFlow charge during the trial period
Trial eligibility Available to eligible paid-plan accounts
Auto-activation When the trial ends, the 10Gbps tier is added automatically unless you stop the trial
Trial retention Trial tenants are kept on a strict 48-hour retention window to control storage cost

After the Trial Expires

When the trial expires, new data collection pauses unless the add-on is active. Trial tenants remain on the strict 48-hour retention window.

Activate before the trial ends if NetFlow is part of your daily NOC workflow. This avoids gaps in traffic history.

Billing and Invoices

When a NetFlow tier is activated (manually or via auto-activation), ISPBills generates an invoice and attaches the recurring add-on to your subscription. The add-on also appears on renewal invoices while it remains active.

Billing event Result
Trial started No immediate invoice
Tier activated (10/40/100Gbps) Invoice generated for the add-on and the tier is attached as recurring

Stopping Auto-Activation

If you do not want NetFlow to auto-activate after the trial, open Monitoring → NetFlow during the trial and select Stop trial. This immediately ends trial access and disables auto-activation.
