Advanced firewalls like the Sophos XGS and FortiGate series offer a lot more than just various throughput specs. Other notable focal points include deep packet inspection, automation, app control, and real-time threat intelligence.

Businesses have quite a few areas to consider to end up with the right firewall hardware. It isn’t just about what the tech can do, but how it aligns with your overall network security goals. Nevertheless, it starts with breaking down important details from the data sheets.

What is the Sophos Firewall XGS 4500?

The Sophos XGS 4500 is a mid-range firewall on the surface, but the specs are much more impressive than you might expect. Offering high performance with a simple management interface, this particular model is rated to support up to 2,500 users.

Here’s a deeper look into what can be expected from the firewall:

  • Firewall Throughput: 80 Gbps
  • IPS Throughput: 36.5 Gbps
  • Threat Protection Throughput: 31.85 Gbps
  • IPsec VPN Throughput: 75.55 Gbps
  • Concurrent Connections: 17,200,000

As impressive as these numbers are, that doesn’t mean it’s an automatic go-to solution for every business. Moreover, it isn’t hard to find other firewalls on the market that fall into a similar category.
