Hi Guys, I have some question regarding the PI system, is it possible to use PI system to collect data through internet connection, which is the data source is far away. and not using the 3rd party VPN software.

As long as the server/interface has a way to connect to the remote source, there's no issue (although using native PI interfaces can take some time to initially start with high latency). However you make that connection is up to you, whether you use a VPN software or not.
