  data protection cloud provider. Example providers with this type of service 
  are Zscaler, Scansafe, and Onavo.
- `dns` - A proxy used by overriding the client's DNS value for an endpoint 
  host to that of the proxy instead of the actual DNS value.
- `google` - Google's built-in proxy, also known as Google IP Protection.
- `tor-exit` - The gateway nodes where encrypted or anonymous Tor traffic 
  hits the internet.
- `tor-relay` -  Receives traffic on the Tor network and passes it along. 
  Also referred to as "routers".
- `vpn` - Virtual private network that encrypts and routes all traffic through 
  the VPN server, including programs and applications.

  through mobile device web browser software that proxies the user through a
