ProtonMail launches standalone iOS app | Computerworld
Proton VPN routes users through encrypted tunnels, and the iOS VPN app supports advanced security features, such as Secure Core, which transmits mobile user traffic through multiple servers (325 servers are available) to defend against bad actors trying to track mobile IP addresses and Tor via VPN. The new app also uses the latest Internet Key Exchange protocol (IKEv2), which provides faster speed and stability on a VPN network.
I'm always looking for better VPN services. I started with Protonmail years ago when I was looking for a better way to send tax documents. I liked what Protonmail had to say about privacy. I really like what they are saying about VPN now. But who knows, I can be a sucker on two accounts.
I think VPN is a good thing, but is too complicated for most of us to understand. There is much confidence (or ignorance) required to use them. I do not already trust mobile operators or ISPs, so the question is who do I misunderstand. An advantage of a VPN in my real life is that a VPN can often get around network restrictions that prevent SFTP or SSH access. This is something I regularly run when I try to manage a server while on a mobile device. VPN hides some traffic and removes some network filters.
