I’ve been using ProtonVPN for a while and I just saw this for the first time when I opened it a little while ago. Can someone explain this to me? Is this notice from Apple or Proton VPN? Does this mean Apple is filtering or monitoring my activity when I use VPN? Why am I only seeing this now?
Default message from mac OS about theoretical possibilities of any VPN.
What do they mean by “filtering” my activity when I’m using VPN?
I forgot to add that it says on top of the notice…
“ProtonVPN” Would Like to Add VPN Configurations
On the bottom, there are options ‘Allow’ and ‘Don’t Allow’
So I guess the theoretical possibilities have always been there…why am I only seeing this now?
The VPN provider can have firewall rules and can restrict the sites you are allowed to visit.
This is typically the case for company VPNs as they don’t want employees to e.g. watch certain stuff at work.
Also the same is true for Proton’s free tier, those servers are blocking P2P Traffic. 
To be able to connect to a VPN, a VPN configuration has to be added, thats normal.
why am I only seeing this now?
Likely because you did zero research on what a VPN is before using one.
Probably added in an OSX update.
did you recently update to Ventura? There are quite a few new privacy/security popups in that version
That makes sense except Nelizea says this was a default macOS message.
I actually opted “Do not allow” and not I’m not able to connect. Is there any way to allow the configuration?
that’s not what I think happened : he used the same VPN on the same OS and the OS did not put that message the first time. But now the OS is showing this message. OP is asking why the OS didn’t show the message the first time.
At least that’s what I think OP meant.
Likely because you did zero research on what a VPN is before using one.
So why didn’t the popup come up all the other times I used Proton? Is that also because I did zero research? Since you did lots of research, can you answer my questions?
If I’ve been using the same VPN on the same OS for a while and this popup comes up only now, how does asking why mean I did zero research on what a VPN is?
I don’t remember if I recently updated to Ventura, I only know I’m on Ventura 13.2.1 now, but thanks for the info, maybe that’s the reason.
Default in the sense that macOS is generally warning when adding VPN configuration‘s, as it is out of Apple‘s control what the VPN services are doing.
Try reinstalling the app
