Virtual private networks
What is a VPN
Technically, there are a number of different 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
