One of the more popular options in the VPN space is Private Internet Access. It made a name for itself by being notoriously cheap at around $40 per year, despite its desktop interface being kind of terrible at the time. These days you won’t find PIA as cheap as that, but the desktop app is a lot nicer. Plus, you get a ton of country options, good speeds, and for power users the ability to tweak your connection security.
