HenkTek earns a small commission if you buy through the Amazon links in this post. It doesn’t change the price you pay, and it doesn’t change which boxes we’d recommend.
It’s a common story. An office upgrades to gigabit fiber, runs a speed test, and gets about a third of what it pays for. The ISP wasn’t lying. The firewall in the closet was the bottleneck, and in plenty of cases it had stopped getting security updates a long time ago. That’s usually the moment people start asking about firewall replacement in Fort Myers, and it’s a fair time to ask.
This post covers how to tell when your current box has to go, the one spec sheet number that actually matters, and the gear we’d put in a small Southwest Florida office today. Our picks are based on manufacturer spec sheets and current pricing, not on a lab test, and we say where each one falls short.
Five signs your firewall is done
Any one of these is enough of a reason. Two or more and you’re overdue.
- The vendor stopped shipping firmware for it. An end of support firewall still passes traffic, so nobody notices, but every new hole found in it stays open forever. In February 2026 CISA ordered federal agencies to find and pull these devices (Binding Operational Directive 26-02) because attackers keep using them as the front door. A dental office in Cape Coral isn’t bound by that order, but the logic is the same.
- Your internet is faster than the firewall can inspect. More on this below, because it’s the one people miss.
- The security subscription lapsed. FortiGate, SonicWall and WatchGuard boxes lean on yearly licenses for the filtering and intrusion prevention. When the license runs out, many of them keep routing traffic and stop protecting anything.
- It’s the combo modem and router the ISP dropped off. Those were built to get you online, and the firewall settings are thin.
- It took a hit during storm season and now reboots on its own or drops the VPN. Lightning and surges in Lee County kill network gear every summer, and a half dead gateway is worse than a dead one because it fails at random.
The throughput number that matters
Every firewall box has a big number printed on it. Ignore it. That’s routing speed with the security features turned off, which is the one way you should never run it.
The number you want is the speed with intrusion prevention (IDS/IPS) switched on. That’s the part that inspects traffic for known attacks, and it eats CPU. A few examples from the spec sheets: Ubiquiti rates the UniFi Cloud Gateway Ultra at 1 Gbps with IPS on, and the Cloud Gateway Max and Express 7 at 2.3 Gbps. The Firewalla Purple SE is built for lines under about 500 Mbps. Fortinet lists the FortiGate 40F at 5 Gbps of firewall throughput, but its threat protection number (the one with the security stack running) is 600 Mbps.
So if you pay for 1 gig and your firewall inspects at 600 Mbps, you have two choices: turn the protection off to get your speed back, or accept the slowdown. Most offices end up doing the first one without realizing it (someone “fixes” the slow internet). That’s the case for a firewall replacement right there.
Quick rule: buy a box whose IPS number is at least as fast as your internet plan, with some room for the next upgrade.
What we’d put in a small Fort Myers office today
Prices below are what Amazon showed on October 6, 2026 (Prime Big Deal Days), so expect some to move.
UniFi Cloud Gateway Ultra, for most offices under 15 people
$139 on Amazon. It inspects at 1 Gbps, which covers a standard gigabit plan, has a 2.5 GbE internet port and four 1 GbE ports, and it can run up to four internet connections for failover (handy if you followed our backup internet advice). There’s no monthly fee. Two limits worth knowing: it only runs UniFi Network, so no cameras, and Ubiquiti’s own help docs list it among the gateways that don’t support Traffic Flows, the log that shows who connected to what. If an insurer or auditor ever asks you for that kind of record, skip to the Max.
UniFi Cloud Gateway Max, if you have cameras or faster internet
This is the one we’d pick for a medical or law office. It inspects at 2.3 Gbps, every port is 2.5 GbE, and the 512 GB version records UniFi Protect cameras (up to 15 HD, per Ubiquiti) and keeps the Traffic Flows log. Amazon had the 512 GB model at $327 on October 6. Ubiquiti’s own store lists it at $301 with the surcharge, so check both before you order. If you’re comparing it against a rackmount Dream Machine, our UDM Pro vs SE vs Pro Max breakdown covers the bigger boxes.
UniFi Express 7, for a two or three person office
$234.95. Gateway and WiFi 7 access point in one small box, with the same 2.3 Gbps IPS rating as the Max and a 10 GbE internet port. The catch is ports: there’s exactly one LAN port, so you’ll need a small switch for a printer and a couple of desktops. Ubiquiti rates its WiFi coverage at about 1,750 square feet, which fits a small suite on Colonial Boulevard and not much more.
Stock note, checked October 6, 2026: Amazon had no featured offer on the UniFi Express 7. Ubiquiti also sells it at store.ui.com.
Firewalla Purple SE, if you want it run from your phone
Around $289 on Amazon (the listing defaults to the Purple SE, double check the model before you buy). No subscription, a very good phone app, and it shows you which device triggered which alert in plain language. It sits behind or replaces your existing router. The limit is speed: roughly 500 Mbps with IPS running, so it’s for offices on a slower cable plan, not gig fiber.
What about FortiGate? It’s a fine firewall and some cyber insurance questionnaires like seeing the name. Just price the whole thing. The 40F is about $428 on Amazon as bare hardware, and the security bundle is a separate yearly license (European resellers list one year of Fortinet’s UTP bundle at around €395). If nobody is going to renew that license every year, buy one of the boxes above instead.
Firewall replacement in Fort Myers: don’t skip the boring parts
The hardware is the easy half. Before the old box comes out, export its config or at least screenshot every port forward, VPN account and static IP reservation, because something in the office (the door system, a camera recorder, the phone vendor’s remote access) is always depending on a rule nobody wrote down. Do the swap after hours. Turn on automatic firmware updates on the new one, then actually check a month later that it updated. And put it on a UPS with surge protection; a $140 gateway plugged straight into the wall is the first thing the next lightning strike takes out (our UPS vs power station guide covers that).
If your office runs on older UniFi gear already, the Dream Machine review is a good read before you buy anything new. For the rest of the network, see our small business IT equipment list.
