With ProtonVPN's stated mission of protecting individuals' digital lives, a natural progression for Proton and its VPN is to include scam calling screening and protection into the digital tools that Proton provides currently. This would be best integrated into the VPN app, where it would be most effective in monitoring calls and providing forewarning and steps for potential scams. This type of feature is provided with NordVPN service, which is another powerful VPN tool with decent security measures, which makes me believe that Proton would be able to improve on this service with ProtonVPN, enhancing our digital security even further.
