Sophos XGS 4500 vs Fortinet, Meraki, Palo Alto

Sophos XGS 4500 vs Fortinet, Meraki and Palo Alto

A like-for-like look at the Sophos XGS 4500 against the FortiGate 400F, Cisco Meraki MX250 and Palo Alto PA-3440. The XGS 4500 publishes 80 Gbps firewall throughput, 31.85 Gbps threat protection and 10.6 Gbps of TLS inspection. Where a competitor leads, the table below says so.

One caveat before the numbers: vendors measure throughput differently, so these figures are not laboratory-equivalent. Use them to narrow the shortlist, then test on your own traffic.

The Sophos XGS 4500 is the top of the 1U range and, on paper, close to enterprise territory: 80 Gbps of firewall throughput, 10.6 Gbps of TLS inspection, and 8.39 Gbps of threat protection in a single rack unit. Buyers at this level are usually protecting a large campus or a data-center edge and cross-shopping the biggest rackmounts from Fortinet, Cisco Meraki, and Palo Alto. USD pricing below.

This is the tier where spec-sheet comparison is least useful, because each vendor measures at a scale and method of its choosing. Anchor the decision to your throughput ceiling, your inspection needs, and how you want to manage it.

Sophos XGS 4500 and its rivals

All figures vendor-published (sophos.com, fortinet.com, documentation.meraki.com, paloaltonetworks.com), measured by differing methods. USD, checked September 7, 2026. Where a competitor figure is not confirmed in the current datasheet, it is marked as such rather than estimated.

The honest read

The 4500’s headline is that 10.6 Gbps of native TLS inspection, the highest in the 1U range and a genuine differentiator if decryption at scale is your requirement. To match it you would look at a large Palo Alto or Fortinet, at which point licensing and rack space enter the conversation. Cisco Meraki tops out below this on the MX line and still inspects HTTPS only through an extension. As always, if a single raw number decides it, compare the exact models you are quoting; if bundled, cloud-managed decryption at scale is the goal, the 4500 is the 1U built for it.

The top of the 1U range

With 10.6 Gbps of native TLS inspection and 8.39 Gbps of threat protection, the 4500 pushes into territory that usually means larger, more expensive platforms from other vendors. If decryption at scale in a single rack unit, bundled and cloud-managed, is the requirement, the 4500 is purpose-built for it. If you only need part of that capability, a model a tier down will likely serve and cost less.

Questions buyers ask

What makes the XGS 4500 the top 1U model?

It leads the 1U range on TLS inspection (10.6 Gbps) and threat protection (8.39 Gbps), suiting large campus and data-center-edge decryption at scale.

Would a smaller model do the job?

Often yes. If you do not need the 4500’s decryption and throughput ceiling, a 4300 or 3-series model usually costs less and fits.

Do the throughput numbers compare directly across vendors?

No. Sophos and Fortinet use large UDP packets, Palo Alto uses an application mix, and Cisco Meraki quotes stateful-firewall figures for a cloud appliance. Compare the security-enabled row and your traffic.

Which of these can Nuformat sell me?

Sophos and Fortinet. Cisco Meraki and Palo Alto are here for comparison only.

Three ways to buy a Sophos XGS firewall

Sophos now sells the XGS and its Xstream Protection in more than one way, which is worth weighing before you commit:

• Buy outright, term license. Purchase the appliance with a 1, 3, or 5-year Xstream Protection subscription paid upfront, and own the hardware. The 12-month Xstream figure quoted here is this option.
• Own the hardware, license monthly (MSP Flex). Buy the appliance outright, then pay for the Xstream Protection license monthly through a Sophos MSP partner’s MSP Flex billing instead of a multi-year term upfront. Billing is monthly, in arrears based on usage.
• Hardware as a Service (HWaaS). Launched July 1, 2026 for MSPs in the US and Canada, HWaaS combines the appliance, standard shipping, and Xstream Protection into a single monthly price billed through MSP Flex. It carries a mandatory 12-month initial term, then continues month to month, on select XGS models.

MSP Flex and HWaaS are delivered through a Sophos MSP partner. Ask Nuformat which fits your budgeting.
