Firewall comparison · Updated September 2026

Sophos XGS vs. Fortinet FortiGate

We sell and support both, so this is the comparison we give our own customers: where Sophos leads, where Fortinet leads, and how to choose for your size, your team, and what else you run.

The short version

Both are complete next-generation firewalls with SD-WAN, IPS, sandboxing, and web filtering, and both are backed by a strong vendor. The difference is how much comes in the box, how the firewall works with your endpoints, and how much raw throughput you get per dollar.

Sophos: one system, less to bolt on

Cloud management, reporting, and endpoint coordination come with the firewall. If you run Sophos endpoint or MDR, the firewall becomes part of that system on day one.

Fortinet: silicon and breadth

FortiGate runs on Fortinet's own security processors, so IPsec and inspection throughput per dollar is hard to beat, and the Security Fabric reaches switches, Wi-Fi, SASE, and ZTNA.

Either way, size it with a human

A wrong-sized firewall is the most common mistake we see. Tell us users, sites, WAN speed, and what you inspect, and we will quote the right model from either vendor.

Side by side

What each vendor documents for its current shipping platform: Sophos Firewall OS on XGS appliances, and FortiOS on FortiGate F and G series appliances.

Capability Sophos XGS Fortinet FortiGate
Cyber defense system Sophos FusionFirewall, endpoint, email, switches, and Wi-Fi report into one system with 500+ integrations, agentic AI, and human MDR analysts on the same data. Security FabricFortinet products share intelligence through the Security Fabric. Broader outcomes usually depend on separately deployed products, licenses, and consoles.
Firewall hardening and updates Protection built inHardened, containerized firewall with secure defaults, health checks, integrity monitoring, and over-the-air hotfixes that do not need a reboot. Firmware-led maintenanceFortiOS is mature and well supported, but critical fixes usually arrive as firmware releases that need a maintenance window and a reboot.
Central management and reporting Sophos Central, includedCloud management, reporting, zero-touch deployment, and firmware updates for firewalls, endpoints, switches, and access points at no extra charge. FortiGate Cloud, FortiManager, FortiAnalyzerFortiGate Cloud covers basic cloud management. Fleet configuration, long-term logs, and deep reporting come from FortiManager and FortiAnalyzer, which are separate products.
Endpoint and firewall working together Synchronized SecuritySecurity Heartbeat lets the firewall isolate a compromised endpoint automatically, and Active Threat Response blocks known bad traffic without a rule change. Security Fabric with FortiClient EMSFabric integration can quarantine endpoints, but it relies on FortiClient EMS, fabric connectors, and administrator configuration.
Network detection and response NDR in the firewallNetwork detection and response runs on the firewall itself and feeds XDR and MDR, including signals from encrypted traffic. FortiNDR, separateFortinet sells NDR as a separate appliance or cloud service rather than inside the firewall.
Licensing Two bundles, no add-on mazeStandard or Xstream Protection covers the firewall, with Enhanced Support and cloud management included. Add-ons are limited to Web Server Protection and Email Protection. FortiCare plus FortiGuard bundlesSupport (FortiCare) and security services (FortiGuard Unified Threat Protection or Enterprise Protection) are licensed separately, and central management is another line.
Managed detection and response Sophos MDR across control pointsThe MDR team watches firewall, endpoint, email, identity, and cloud telemetry, plus supported third-party tools, 24/7. MDR Plus adds full incident response. FortiGuard MDRBuilt around Fortinet telemetry and FortiEDR. Broader response scope can require additional services.
Throughput per dollar Xstream architectureStrong inspection and TLS performance for the price in the desktop and 1U ranges, without custom silicon. Fortinet security processorsPurpose-built NP and SP chips give FortiGate very high IPsec and firewall throughput per dollar, especially on mid-range and high-end models.
SD-WAN SD-WAN with Central OrchestrationIncluded with Xstream Protection; orchestrated site-to-site links from Central. Secure SD-WAN in FortiOSFortinet's SD-WAN is a market leader and is built into every FortiGate at no extra license.
Switches, Wi-Fi, and remote access Firewall, switch, Wi-Fi, SD-REDXGS firewalls, Sophos Switches, AP6 access points, and SD-RED are managed together in Central. FortiSwitch, FortiAP, FortiClient, FortiSASEA wider fabric: switches and access points managed from the FortiGate, plus Universal ZTNA and SASE options.

Sophos wording is drawn from Sophos's own comparison material and datasheets; Fortinet capabilities are summarized from Fortinet's FortiOS, FortiManager, FortiAnalyzer, and FortiGuard service descriptions. We sell both lines and have no reason to tilt this table; if you think a cell is out of date, tell us.

Which one fits you

Choose Sophos XGS when

  • You run, or plan to run, Sophos endpoint protection or Sophos MDR and want the firewall to isolate compromised machines by itself.
  • You want cloud management, reporting, and support in the price, with two licensing choices instead of a bundle matrix.
  • Your IT team is small and you would rather manage firewalls, switches, Wi-Fi, and endpoints in one console.
  • You inspect a lot of encrypted traffic on a desktop or 1U appliance and want TLS 1.3 inspection at line rate.

Choose Fortinet FortiGate when

  • You need the most IPsec and inspection throughput per dollar, particularly on mid-range and high-end models.
  • You are standardizing on the Security Fabric: FortiSwitch, FortiAP, FortiClient, FortiSASE, and Universal ZTNA.
  • SD-WAN is the main job of the firewall and you want it native in the OS across dozens of sites.
  • You already own FortiManager and FortiAnalyzer, or your MSP manages you through them.

Common questions

Is Sophos XGS or FortiGate more secure?+

Both hold their own in independent testing and both ship IPS, sandboxing, web filtering, and TLS inspection. The practical difference is coordination: Sophos ties the firewall to its endpoint and MDR service out of the box, while Fortinet reaches the same outcome through the Security Fabric with FortiClient EMS and, for larger estates, FortiAnalyzer.

Which is cheaper over three years?+

It depends on what you count. Sophos includes cloud management and reporting in Standard and Xstream Protection. Fortinet appliances often cost less per unit of throughput, but FortiManager, FortiAnalyzer, and FortiClient EMS are separate lines if you need them. Send us your sites and user counts and we will quote both on the same terms.

Can I move from FortiGate to Sophos XGS without downtime?+

Yes. We map your FortiGate policies and VPNs to Sophos Firewall, stage the XGS beside the FortiGate, and cut over in a maintenance window. Sophos Firewall also includes a migration assistant for common configurations.

Does Nuformat really sell both?+

Yes. We are a Sophos Silver Partner and an authorized Fortinet partner, and we quote both for Canada and the USA. That is why this page ends with which one fits you rather than a single winner.
