How realistic and safe is it that you create your own VPN for complete anonymous browsing?
Think about this. How do you achieve anonymity through a VPN?
By dozens or hundreds of others using the same VPN server as you.
If you’re the only person ever to communicate with the VPN server it’s pretty easy to put 2 and 2 together.
Yes, your data from your PC to the VPN server will be encrypted end to end. BUT at the VPN headend that data gets unencrypted, sent over the clear to its destination.
So authorities see a cyber attack from some unknown VPN server. Who was communicating with that server at that time, they might ask. Oh, it’s just Jim down the street! He’s the only person ever to communicate with that malicious VPN server, it’s him.
