Mullvad.net

I've been testing Mullvad VPN now for a few weeks. The service is good, the customer service is okay, and the security is very good. Mullvad doesn't require any information about you to sign up. Just generate an account number, add time to the account (5 euros for a month) and surf. You can even pay with BitCoin to help with anonymity. They don't keep logs so there is nothing to give to authorities, should an order arise. The only problem is with this anonymity comes people that abuse the system. In doing so, there are increasing numbers of sites that are blocking Mullvad's IP addresses. I used to order food through a food delivery service. Worked fine with other VPNs, but they block Mullvad. Edit: Since this review was first published, Mullvad has added more servers and the new ones aren't blocked like the old ones.
Mullvad uses up to date encryption and protocols. OpenVPN and Wireguard are the two protocols. Wireguard is fast, but you may have problems generating wireguard encryption keys if your ISP blocks Mullvad's API. May ISPs do. The solution would be to generate the keys inside the encrypted tunnel using OpenVPN, but obviously they haven't figured this out yet. They do, however, offer OpenVPN on port 443 in order to bypass VPN restrictions set in place by your ISP. They also offer double hopping or bridged connections. You connect to one VPN server and your traffic is routed through another VPN server, making it very difficult to trace where you are visiting.
Mullvad is located in Sweden. While it is in a 14 eyes country, Sweden has very strict privacy laws protecting consumers. Even if there was an order to hand over logs to authorities, there are no logs to hand over.

Edit: Mullvad has since added several virtual servers to their network which temporarily solves the blocked sites problem. These servers only add new IP addresses that are 'clean' and unblocked... for now. These are leased servers and not owned by Mullvad, which can be a security issue.
