Traffic leaking has always been a concern when sitting up a VPN or any network infrastructure. Especially when you’re dealing with sensitive data. These concerns are old, and not sensational, new traffic leak discovered in local routing configuration of some VPN clients.

The truly paranoid would have a always-on VPN, no traffic may go outside the VPN, defense in depth. A VM that can only talk to the VPN endpoint. You could use qubes to configure something bulletproof, mullvad even has an article explaining how to do this yourself.

Just out of good hygiene I have leak checks in my computing systems. If they succeed it shuts everything down. Like if you open a browser it checks your external facing IP address. Imagine it’s pretty common for people.
