Not sure which firewall your business needs? Answer three quick questions and get a recommended Fortinet, Sophos or SonicWall model for your size, throughput and features — then a same-day quote from Invitty, India's authorized firewall dealer.
As a rough guide, here's how business size maps to firewall tier and representative next-generation firewall (NGFW) models. Throughput needs and advanced inspection can push you up a tier — the tool above accounts for that.
| Business size | Tier | Fortinet | Sophos | SonicWall |
|---|---|---|---|---|
| 1–25 users (small office) | Entry NGFW | FortiGate 40F / 60F | Sophos XGS 88 / 108 | SonicWall TZ270 / TZ370 |
| 25–100 users (growing business) | Mid-range | FortiGate 70F / 90G | Sophos XGS 118 / 128 | SonicWall TZ470 / TZ570 |
| 100–300 users (multi-department) | Performance | FortiGate 100F / 120G | Sophos XGS 136 / 2300 | SonicWall NSa 2700 |
| 300+ users / HQ / data-centre | Enterprise | FortiGate 200G / 400F+ | Sophos XGS 3300 / 4300+ | SonicWall NSa 3700+ |
Note: models are indicative. The right choice depends on your actual internet bandwidth, the security features you enable (IPS, sandboxing, TLS/SSL inspection reduce effective throughput), concurrent sessions and VPN needs. Invitty's firewall team will confirm exact sizing before you buy.
A firewall's headline throughput is measured with security features off. Turn on IPS, application control, web filtering and TLS inspection — which is the whole point of a next-gen firewall — and real throughput can drop by 60–80%. Under-size, and your internet crawls the day you actually switch on protection. Over-size, and you've paid for capacity you'll never use. Right-sizing gets you full protection at line speed without overspending, and Invitty quotes the appliance plus the correct licence bundle in INR with a GST invoice.
Match the firewall to three things: how many users and devices it must protect, the internet throughput you need with security features (IPS, sandboxing, TLS inspection) switched on, and features like SD-WAN or multi-site VPN. Under-sizing throttles your internet once threat protection is enabled; over-sizing wastes budget. This tool maps your inputs to the right tier and representative Fortinet, Sophos and SonicWall models.
For most small offices (up to ~25 users) an entry NGFW such as a Fortinet FortiGate 40F/60F, Sophos XGS 88/108, or SonicWall TZ270/TZ370 is the right tier — enough for secure internet, VPN and basic threat protection. Exact choice depends on your internet speed and whether you need advanced inspection.
The hardware is only part of the cost — firewalls need a security subscription (threat protection, IPS, web filtering, support). We quote the appliance plus the right licence bundle in INR with a GST invoice, and handle renewals so you are never unprotected.
Yes. Use this tool for a quick shortlist, then we do a precise sizing based on your real throughput and traffic mix, supply the genuine appliance and licence, and install, configure and support it across Chennai and India.
