[Trisquel-users] Re : Spying by the ISP

[lcerf]

Indeed.  If the protocol is unencrypted, the ISP sees everything; if it is  
encrypted, it cannot see the content but still sees the meta-data, which is a  
lot of information too.  Using a VPN makes the ISP only see encrypted traffic  
to it.  With Tor, even a powerful attacker will have trouble to know what you  
do on the Internet.
