Sophos Firewall Virtual is a virtualized firewall appliance for organizations that already run a supported hypervisor. Whether it is a good fit depends first on platform compatibility and licensed VM resources, then on which security subscriptions your workload requires. Sophos documents a 30-day evaluation, but the available official material does not establish independent performance results; throughput and latency need to be measured on the configuration you plan to use.
What Sophos Firewall Virtual is—and who should consider it
Sophos offers Firewall in hardware, virtual, and software formats. Its deployment documentation describes virtual appliances for network security in virtual data centers and lists VMware, Hyper-V, KVM, and Citrix Hypervisor as hosting environments. That list is an orientation, not a guarantee that every version is supported: check the supported-version matrix for the SFOS release and hypervisor you intend to run.
This product is most relevant if you already operate a compatible virtualization environment and want firewalling as a VM. It is not a plug-and-play appliance decision: host compatibility, virtual network interfaces, storage, assigned resources, license limits, and subscriptions all affect whether the intended deployment is viable.
Check the host requirements before choosing a license
Published minimums differ by platform and documentation version, so treat them as platform-specific prerequisites rather than a universal sizing recommendation.
#1 Best Overall
- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
| Documentation and scope | Minimum resources |
|---|---|
| General virtual deployment options, Sophos documentation dated 2022 (deployment options) | 1 vCPU, 4 GB vRAM, 2 vNICs, 16 GB primary disk, and 80 GB report disk |
| KVM, SFOS 22.0 guide published March 4, 2025 (KVM deployment guide) | 1 vCPU, 4 GB vRAM, 2 vNICs, 32 GB primary disk, and 80 GB report disk |
The KVM guide additionally calls for an x86 server with a recent Linux kernel and an Intel processor with VT extensions or an AMD processor with SVM/AMD-V extensions. Sophos warns that a system below minimum requirements enters fail-safe mode. For KVM operations, it also says backups of the firewall made with virtualization-vendor backup tools are not supported; account for a supported backup approach rather than assuming a VM-level backup is sufficient.
Minimums are not performance targets
Meeting the minimum only establishes a documented floor; it does not show that the VM will handle your traffic or enabled inspection features. Sophos says to size vCPU and vRAM according to the purchased license and not exceed that license’s maximum. A larger VM allocation is not automatically licensed, nor does the documentation establish that adding vCPUs will improve performance in every workload.

Understand what the base license does—and does not include
Sophos says an SFOS base license is required for both hardware and virtual firewalls. Additional features are sold as subscriptions, either separately or in bundles; for a virtual firewall, the buyer must obtain the base license plus the desired subscriptions, or choose a bundle that includes them. Confirm the specific tier, feature coverage, resource limits, term, and region-specific offer with Sophos or an authorized partner. The cited documentation does not establish a universal current price.
The distinction matters because the base license alone may not provide enforceable security protection. Sophos’s licensing page, dated January 30, 2026, states: “Security protection on Sophos Firewall requires a subscription. You can configure firewall settings, but they can’t be enforced without a valid subscription.” Review the subscriptions needed for the protections you intend to use before treating the base license as the total cost of ownership.

CPU limits are license-specific
Sophos licensing documentation says virtual firewall licenses are limited by maximum CPU cores. One example in its FAQ is a virtual Xstream Protection license that can be limited to four CPU cores. That is an example for a particular license, not a universal cap; verify the exact maximum for the license you plan to buy before assigning resources or estimating capacity.
Use the documented trial to validate your own workload
Sophos’s virtual firewall trial setup page, dated September 14, 2026, describes an eligible-user free 30-day evaluation through Sophos Fusion. It directs users to download an installer for their platform and says trial license features are activated. Eligibility and the live offer can change, so verify the current terms on the virtual firewall trial setup page before planning a test window.

- Check that your hypervisor and version are supported for the SFOS release you want to evaluate.
- Confirm the VM has the applicable platform minimums and that the planned CPU and memory allocation fit the trial’s terms.
- Start the evaluation through Sophos Fusion, then download and deploy the installer intended for your platform using Sophos’s current setup instructions.
- Test the actual traffic mix and security features you expect to run, and record the configuration and results before the evaluation ends.
If you later convert the trial to a purchased virtual license, Sophos’s licensing FAQ says a new serial number may be generated and the purchased license must be transferred to the trial serial. Check the current licensing FAQ for the active transfer steps.

There is no defensible throughput, latency, VPN-capacity, or detection-rate verdict without a named configuration and reproducible test. Sophos’s deployment and licensing documents establish setup and licensing facts, not independent benchmark results. A review that gives a single performance figure without its environment and test conditions is not enough to predict how the VM will behave in your network.

For a meaningful evaluation, report:
- Host CPU, memory, and storage, plus the hypervisor and version.
- SFOS version, assigned vCPU and vRAM, and virtual NIC configuration.
- License and subscriptions, along with the inspection and security features enabled.
- Traffic mix, test duration, and measurement method.
- Comparable results from the same workload and feature set if comparing products.
For a deployment decision, also compare supported hypervisor versions, licensed resource ceilings, subscription coverage and cost, setup and management workflow, high-availability requirements, and operational constraints. A trial can establish whether your specific setup works; it cannot substitute for a clearly documented test when making broader performance claims.
