I think that’s good vpn-providers on this list. The problem is with NordVPN and other VPN Providers is that there are located in usa. For a save data environment you can’t choose usa companies because of the NSA etc. Because if the want your data form the vpn provider, they get it. There a lot of stories from a data leak in the usa. So choose only vpn providers from European countries with a good social policy like schweden, Austria, switzerland or sweden for example.
Don’t get my wrong i like lot of things in the usa and a lot of companies but the government is on of the worst in the hole world.
