Microsoft Hyper-V

You can deploy the Sophos Firewall virtual appliance on the Microsoft Hyper-V platform.


  • Install Microsoft Hyper-V Server 2008 or 2012 on a server that meets the minimum hardware requirements below. For instructions, go to Server 2008 or Server 2012.
  • Install Hyper-V Manager (Hyper-V management software) on a management device that has network access to the server. For details, go to Hyper-V Manager.
Hardware Specification

vRAM 4 GB minimum
vNIC 2
Primary disk 16 GB minimum

If you don't meet the minimum requirements for new installations of SFOS 18.0, or if you're migrating from an earlier version, Sophos Firewall goes into fail-safe mode.


Configure the vCPU and vRAM based on the purchased license. Don't exceed the maximum number of vCPUs specified in the license.
