Which servers can I connect to for free?

If you're on our free plan, we'll automatically connect you to one of our free servers in the Netherlands, Japan, Romania, Poland, or the United States. Upgrade to Proton VPN Plus to get access to over 3,000 servers in more than 70 countries.

What is the difference between a kill switch and a permanent kill switch?

Proton VPN for Linux has both a kill switch and a permanent kill switch. When you turn the kill switch on, Proton VPN disables the internet if your VPN connection is interrupted to hide your real IP address. When you turn the permanent kill switch on, your internet connection is blocked all the time unless you’re connected to a VPN server. That means your internet connection will also be blocked when Windows is starting up and shutting down and whenever you manually disconnect the VPN.

Is there a command-line version tool?

Our official (v4) Linux doesn’t yet support a command line tool. If you need a CLI, you can still use our old (v3) CLI tool.
