Love ProtonVPN But

ProtonVPN really needs a permanent kill switch for its macos app, as I have it drop repeatedly while switching between servers. The server cannot connect to the new one for whatever reason and then everything is exposed, as it just states not connected.

I use the app on my IOS devices and love the aesthetics of it on my mac.

Other open source vpn’s have this feature and I am forced to cough up to one of them just to keep my mac secure.

Can’t Proton just look at someone else’s open source code or do at least try something?

They are supposed to be secure in all areas.

A real bummer.

Yes, Proton, please work on this for macOS!

I use a windows 11 pc and iOS for my cell phone so I get the best of both worlds!

On MacOS as well as on iOS it’s not really possible to do a completely proof kill switch.

If you use an VPN apples own connection might not even go through it. On iOS for example the stuff the settings app sends or other system apps ignore the VPN connection.

That’s a limitation of the OS. While other software might make it seem like there’s a complete Killswitch active, in reality that’s not the case.

On MacOS as well as on iOS it’s not really possible to do a completely proof kill switch.

Could you please supply references to support this statement.

I ask because another VPN service does offer both a “regular” kill switch and additionally an enhanced kill switch in their macOS application. They claim that, with the enhanced kill switch enabled, you must be connected to one of their VPN servers to be able to reach the internet.

This VPN service has undergone multiple third-party audits. Are the audits not catching a fault in this enhanced kill switch?

That’s not a fault of the kill switch, it will indeed block connections of user apps, but not of system apps. That’s not possible on iOS or MacOS.

And afaik this issue is still persistent, although Apple claimed to have fixed it.

I was aware of this issue on iOS, but not on macOS. Indeed, I see no mention of macOS in the Proton article that you link.
