ProtonVPN is a Swiss-based virtual private network company that is a subsidiary of Proton Technologies, the company behind secure email service ProtonMail.
ProtonVPN has dedicated apps for Microsoft Windows, macOS, Android, and iOS. For Linux, the company has a command-line tool to offer through which they can secure their connection. ProtonVPN has a collection of 474 servers, available in 36 countries from around the world and all of the servers are owned by ProtonVPN and are operated through the company’s secure network.
ProtonVPN uses OpenVPN (UDP/TCP) and the IKEv2 protocols for the VPN connection. Both of these are secure protocols and the latest in the market. The company respects the privacy of the users by having a strict no-logging policy.
ProtonVPN is one of the securest VPN services out there and uses the latest AES-256 encryption, and prevents DNS and IP leaks of the users, protecting their IP address from being exposed. In case the connection is lost, ProtonVPN has a kill switch which turns off the Internet access to prevent data leaks.
ProtonVPN is also compatible with the TOR browser and you can use ProtonVPN servers to add an extra layer of security when you access the TOR browser. This double security layer will prevent anything from being traced back to you.
The reason why ProtonVPN is a popular choice for VPN software is that it is run by the makers of ProtonMail which is a very secure, end-to-end encrypted email service and that makes the users pick the ProtonVPN due to its security, privacy, and encryption.
