Firewall comparison · Updated September 2026

Sophos XGS vs. SonicWall

SonicWall TZ and NSa firewalls are a familiar sight in small and mid-sized networks. Here is how they compare with Sophos XGS on the things that decide your next three years: what is included, how the firewall works with your endpoints, and who watches it at 3 a.m.

The short version

SonicWall covers the firewall basics well and its Capture ATP sandbox with RTDMI is a solid engine. Sophos goes further on what surrounds the firewall: included cloud management with long-term reporting, automatic isolation of compromised endpoints, network detection built in, and an MDR service that spans more than the firewall.

Included, not licensed later

Sophos Central management, reporting, and Enhanced Support come with Standard or Xstream Protection. SonicWall's suites include cloud management with seven days of cloud reporting; longer retention is an added service.

The firewall talks to your endpoints

Security Heartbeat lets an XGS isolate an infected PC on its own. SonicWall relies on Capture Client integration and administrator policy for the same outcome.

A system, not a box

Firewall, endpoint, email, switches, and Wi-Fi feed one Sophos console and one MDR team. That is the reason most of our switchers give.

Side by side

What each vendor documents for its current platform: Sophos Firewall OS on XGS appliances, and SonicOS 7 on Gen 7 TZ and NSa appliances with the Essential or Advanced Protection Service Suite.

Capability Sophos XGS SonicWall TZ / NSa
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. No direct equivalentSonicWall products can be managed together, but there is no single vendor-engineered system that coordinates firewall, endpoint, email, and human analysts on the same data.
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 maintenanceFixes arrive as SonicOS 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. Network Security ManagerCloud management is part of the protection suites, with seven days of cloud reporting in the Advanced suite. Longer retention and deeper analytics are added subscriptions.
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. Capture ClientSonicWall's endpoint agent integrates with the firewall for visibility and enforcement, but automatic isolation depends on configuration and the Capture Client license.
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. Not built into the firewallSonicWall does not ship network detection and response 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. Essential or Advanced Protection Service SuiteThe Advanced suite adds Capture ATP sandboxing, DNS security, and cloud management to the Essential set. Support, management retention, and endpoint are further lines.
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. SonicWall MDRA newer service built on SonicWall's 2023 acquisition of Solutions Granted, scoped around SonicWall products.
TLS inspection Xstream TLS 1.3 inspectionInspects encrypted traffic at line rate on a dedicated engine, with FastPath offload for trusted flows. DPI-SSLDeep packet inspection of TLS is included; throughput with DPI-SSL enabled drops sharply on smaller TZ models, so size for it.
Switches and Wi-Fi Firewall, switch, Wi-Fi, SD-REDXGS firewalls, Sophos Switches, AP6 access points, and SD-RED are managed together in Central. SonicWall Switches and SonicWaveSwitches and access points are managed from the firewall or NSM.

Which one fits you

Choose Sophos XGS when

  • You want management, reporting, and support included, with two licensing choices.
  • You run Sophos endpoint or want an MDR service that covers firewall, endpoint, email, and identity together.
  • You inspect encrypted traffic and need TLS 1.3 inspection without a throughput cliff.
  • You want network detection in the firewall rather than as a separate product.

SonicWall may still fit when

  • You have a large installed base of SonicWall policy and staff trained on SonicOS, and a refresh cycle is not due yet.
  • Your MSP standardizes on SonicWall and NSM and you are happy with that relationship.
  • You only need the firewall basics at the lowest possible entry price and do not plan to add endpoint or MDR.

Common questions

Can Sophos XGS replace a SonicWall TZ or NSa one for one?+

Yes. XGS 88 to 138 cover the TZ range for desktop deployments, and XGS 2100 to 4500 cover the NSa 2700 to 4700 class in 1U. We match by users, WAN speed, and inspection load rather than by model number.

Will my SonicWall policies migrate?+

We rebuild them on Sophos Firewall as part of the deployment. Address objects, NAT, VPN tunnels, and web policies map cleanly; the SonicWall-specific parts, like Capture Client enforcement, are replaced by Synchronized Security.

What does Sophos include that SonicWall charges for?+

Sophos Central cloud management and reporting, zero-touch deployment, Enhanced Support, and network detection and response come with Standard or Xstream Protection. On SonicWall, longer cloud reporting retention, deeper analytics, and the endpoint agent are separate subscriptions.

Do you sell SonicWall?+

No. We are a Sophos Silver Partner and also sell Fortinet, TrendAI, and other lines. If SonicWall is the right answer for you we will say so, but it is not something we quote.
