Virtual private networks

What is a VPN

Technically, there are a number of different virtual_private_networks#options for VPNs.

Reasons for using a VPN

  • Connect you securely to a remote network (e.g. your office's network). This also means you can apply the same policy controls (such as ad / tracker blocking) that you have on your office network to your mobile traffic
  • Break out to the Internet through a server in a different country (e.g. to make it look like you are in a different country, usually to avoid “geo-blocking” restrictions, where access to a particular service is limited to people in certain countries or blocked from people in certain countries)
  • Hide your traffic from the local network operator

Problems / risks of VPNs

Do you trust your endpoint?

May hide traffic from your local access provider, and other peering or transit providers, but still breaks out to the Internet somewhere, before heading on to its destination

Could just be giving visibility to someone else

Very easy to setup a VPN server and start offering service

VPNs can leak
