Onboard an AWS Environment Into Sophos Cloud Optix (Using Windows 10)

  • You can add your AWS environment to Sophos Cloud Optix using a Linux or macOS computer by using the AWS CLI script or Terraform template provided. Full instructions are provided here: However, if you are not able to use a Linux or macOS computer, you may be able to use the approach described below, using a Windows 10 computer. Please note that this approach is a currently unsupported workaround.
  • The instructions here will only work on a Windows 10 system that supports the Windows subsystem for Linux (version 1609 and above). Earlier versions of Windows Desktop OS (8, 7) and Windows Server OS do not have this feature. Instructions on how to Onboard using a Linux or MacOS system can be found here:
