Firebox T40 vs Firebox T45: WatchGuard Solutions for Small to Mid-Sized Businesses

May 29, 2025

Both the WatchGuard Firebox T40 and T45 serve very similar target markets, but it’s important to look into the details a little further. More important, firewall specifications and the scope of where their end of life (EOL) date lands help you map out the future of your network security.

Even if they’re both great for small to mid-sized businesses, you’re still going to come across quite a few differences in the numbers. This article gives you a clear comparison of the Firebox T40 vs T45 so you can take action with the right information.

Go-To Solutions in WatchGuard Firebox T-Series

Similarities aside, a majority of the differences end up in scalability factors and clear differences in overall performance. If you think your business fits the bill here, then it’s a good idea to see what the datasheet says.

Between the T-Seires and M-Series from the firewall company, you have plenty of room to grow from one device to the next. For the time being, if you’re in the range of small to mid-sized companies, it can feel challenging to choose between the T40 and T45.

What is the WatchGuard Firebox T40?

Promising high-speed connections, comprehensive reporting, and more, the T40 is a great option for getting your network security off the ground. It’s true that it is somewhat limited in terms of scalability, but it acts as a decent segue if you’re just getting started with firewall hardware.

With a quick look, these are the specs you’ll find in the Firebox T40:

  • Firewall Throughput (IMIX): 1 Gbps
  • VPN Throughput (IMIX): 272 Mbps
  • Antivirus Throughput: 623 Mbps
  • IPS Throughput: 510 Mbps
  • Concurrent Connections: 4,300,000

The figures here might seem baseline at best, but you’d be surprised at the long-term support this could offer. A side note to think about here is that the EOL for the T40 comes in 2028, so you’ll have a few years before an upgrade is necessary.

What is the WatchGuard Firebox T45?

WatchGuard products pack a punch, and the Firebox T45 shows this with enterprise-level security built for smaller operations. The specs vary here and there, but the T45 is a bit stronger in many ways compared to the T40.

Here’s how those same categories look with the Firebox T45:

  • Firewall Throughput (IMIX): 1.44 Gbps
  • VPN Throughput (IMIX): 460 Mbps
  • Antivirus Throughput: 874 Mbps
  • IPS Throughput: 716 Mbps
  • Concurrent Connections: 3,850,000

Firebox WatchGuard hardware and their related services go far beyond these points alone. While they act as a solid reference point, you’ll need to know more before you can make the right decision for your business.

If you know what to look for, comparing firewall solutions can be pretty straightforward. From an overall perspective, it can be highly technical, which is what makes the decision-making more difficult than it needs to be. The table below highlights key areas side by side so you can align the numbers with your network demands.
