This question already has an answer here:
I am looking about buying a year pass from Private Internet Access. I am wondering how secure using a vpn is? I have a basic technical idea of how a VPN works, but I still would like to put my mind at ease.
The only person(s) who should be able to see what I'm doing on the internet (aside from seeing I'm using a vpn, just not what I'm using the vpn to do/connect to) are myself, the VPN servers, and then the person I'm connecting to (but they see the vpn, not me). Correct? So my ISP (a home internet provider or university, or someone else), someone connected to the same network as me (home, uni, elsewhere), and people on that public internet cafe that is convenient can't see anything I do (except, again the vpn). Correct?
So I should feel safe p2p file sharing, watching pr0n, or doing my bank anywhere with a vpn?
From what I've read, I've see that vpn secure your internet traffic; but from whom exactly?
Thank's for the help, or if you could point me to another question/resource that answers my question (that I couldn't find), I would appreciate it.
