Introduction to Proton VPN

Proton VPN is part of the Proton family, which also includes Proton Mail, Proton Calendar, and Proton Drive. These services provide end-to-end encryption, protecting user data from prying eyes. Proton VPN, in particular, offers a robust VPN service that masks IP addresses and encrypts internet traffic, making it difficult for third parties to intercept or monitor online activities.

Features of Proton VPN

Encryption and Anonymity

• AES-256 Encryption: Proton VPN uses AES-256 encryption, one of the most secure methods available. This ensures all data is encrypted and unreadable to anyone who might intercept it.
• DNS Leak Protection and Kill Switch: The service offers DNS leak protection and a kill switch, which automatically disconnects the internet if the VPN connection drops, preventing any data from being sent over an unencrypted connection.

Server Locations

• Global Servers: Proton VPN has servers in over 60 countries, providing users with a wide range of options. This allows selection of servers geographically close to their location or in specific regions where access is needed.

Multi-Platform Support

• Cross-Platform Compatibility: Proton VPN supports multiple platforms including Windows, macOS, Android, and iOS. For Linux users, a dedicated client is available, although it has faced some criticism for performance and stability issues.

Free Version

• Limited Free Plan: Proton VPN offers a free version with limited features. The free plan includes access to servers in three countries (Switzerland, the Netherlands, and Japan), useful for casual users wanting to test the service before committing to a paid plan.

Paid Plans

• Enhanced Features: Paid plans offer more features and better performance. The Unlimited plan provides access to all servers and features like the kill switch and DNS leak protection. Additional features include the ability to connect up to 10 devices simultaneously and priority customer support.
