Allow Kill Switch to block Internet when VPN failed to connect on startup.
The kill switch allows you to connect to the internet if Proton VPN failed to connect (during start-up) or if you manually disconnected.
It would be more secure if it only allowed connections through a VPN.
I personally connected to multiple public hotspots without noticing that my VPN was actually off.

It already has this feature as of Jan 2026, and as long as I can remember. Apparently Apple has some sort of issue though because their devices are so **** about being little walled gardens
"Does advanced kill switch protect me when booting up or shutting down my PC or Windows tablet?
Yes. The advanced kill switch creates persistent filters using the Windows Filtering Platform to prevent all internet connections outside the VPN interface. These filters remain in place even when your device is booting up or shutting down."
