You can also run the VPN on a wired router with a software kill switch, then run a Tor proxy on your computer. While the VPN will know your identity and encrypt the traffic from the router to your ISP, the traffic from your computer will be Tor encrypted and unreadable to your VPN provider. Some software can route traffic around computer based VPN software and proxies, but a router based VPN eliminates that potential for an IP leak. It’s also possible to access Proton through Tor and set up a free account for anonymous emailing.
