Proton Drive is currently in beta. Document editing is on our road map for future development. If you'd like to receive notifications about future product releases, contact our sales team.
Proton VPN
A “VPN connection” is any device that is securely connected to the internet using Proton VPN. One VPN connection allows one device to connect to the internet with Proton VPN at any given time. For example, to connect a phone and a laptop to the internet with Proton VPN at the same time, you need two VPN connections.
A VPN allows you to connect to the internet securely. It adds a layer of encryption to prevent WiFi providers and hackers from snooping on your data while you use public WiFi in airports, coffee shops, or co-working spaces. A VPN also prevents internet service providers (ISPs) selling or handing over details of your online activity to third parties, such as advertisers and governments.
Unfortunately, we don't currently offer dedicated IP addresses for your business. This functionality is on our road map for future development. If you'd like to receive notifications about future product releases, contact our sales team.
