2.2 Virtual Appliances
As an alternative to the hardware-based version of the Sophos Web Appliance, you can deploy
appliances as virtual machines using VMware.These appliances can be grouped with other virtual
appliances or with hardware-based appliances. Once deployed, they operate in the same way
as a hardware-based appliance.
Sophos virtual appliances provide a cost-effective web-filtering solution that is easy to set up.
Virtual appliances occupy less rack space, are energy-efficient, and require less hardware.
To learn more about configuring a virtual web appliance, see the Sophos Virtual Web Appliance
Setup Guide or the Sophos Virtual Management Appliance Setup Guide.
Note: Virtual appliances do not support Bridged Deployment, which requires a bridge card.

as well as other virtual appliances.
