I never used VPN, but i want to. Are VPN really safe? I mean are they so safe that even Police can't track your IP? I know how this question sounds, 
but i don't know how to ask quetion about VPN security in better way..
but i don't know how to ask quetion about VPN security in better way..Yes! VPNs are safe. Big companies or businesses are really the ones using VPNs for security and confidentiality of their systems and operations.
