Your firewall is the throttle: a 20 Gbps FortiGate inspects 1 Gbps
FortiGate 100F datasheet throughput with each security engine switched on, where traffic shaping lives, and the Indian price and log rules, as of September 2026.
The 2024 version of this piece defined bandwidth throttling and listed monitoring tools by type. The question behind it is practical: the office link feels slow, so should you cap users, buy a bigger line, or buy a monitoring product? Usually none of the three comes first.
01Shape by application, after you have looked
Shaping lives in the firewall. Fortinet’s FortiOS 7.4 administration guide covers traffic shaping policies, shaping profiles with queuing, shared and per-IP traffic shapers, global prioritisation and DSCP marking.1 The order that works: read the flow data first, then guarantee bandwidth to voice and the ERP, push backups and updates into a capped class, and keep per-IP caps for guest Wi-Fi. Flow data (NetFlow, sFlow) shows who is using the link; ManageEngine sells it as the NetFlow Analyzer add-on to OpManager.2
Two claims from the 2024 version are dropped. Throttling does not add security: a shaper decides how fast traffic moves, not whether it is malicious, which is the job of the inspection engines below. And it rarely defers an upgrade for long: if the business-critical class is starved at peak after shaping, the line or the box is too small, and the flow data will show which.
02The throttle nobody configured
Every firewall datasheet leads with a figure measured with inspection off. Turn the security engines on and the ceiling falls.
Switch on threat protection and a 20 Gbps FortiGate 100F carries 1 Gbps, a twentieth of its headline

03Cost and rules in India
An Indian reseller prices the 100F at about ₹60,000 for the hardware and ₹25,000 a year for the Unified Threat Protection bundle, hardware before GST; add 18% GST and the first year is roughly ₹1,00,300.4 Shaping is part of FortiOS, the operating system the box already runs. CERT-In’s Directions of 28 April 2022 require logs of all ICT systems, firewall logs included, to be kept for 180 days within Indian jurisdiction.5
