There are two elements to server security and privacy for a great VPN service:
The initial is whether or not the VPN provider’s server network is safe and cannot be hacked into by criminals attempting to sniff information and private info or get facts about the all round network configuration and principal server.
The second is the place of the servers. If all the servers AND the VPN provider’s place are in cooperative regions such as the United States and Europe, the safety is about as superior as making use of your local ISP. If none of the servers are in non cooperative or off shore locations, then data retention laws apply to that VPN provider just as if they had been your ISP.
