Understanding the vGW Security VM

To secure the virtual machines (VMs) on an ESX/ESXi host, you install a vGW Security VM on the host. In turn, the vGW Security VM installs the vGW kernel module into the VMware hypervisor of the host. The vGW Security VM acts as a conduit between the vGW Security Design VM and the vGW kernel module. The vGW Security VM also maintains policy and logging information.

You use the vGW Security Design VM to deploy vGW Security VMs to ESX/ESXi hosts. You use it to create firewall policies that are pushed to the vGW Security VMs. The vGW Security VM inserts the policies into the vGW kernel module where all connection enforcement occurs.
