Features
ProtonVPN features Secure Core servers that route traffic through Switzerland, Iceland, or Sweden before reaching the exit server. NetShield blocks ads, malware, and trackers. The VPN Accelerator technology can improve speeds by up to 400%. All apps are open-source and have been independently audited. Integration with ProtonMail, ProtonDrive, and ProtonCalendar offers a complete privacy ecosystem.
Pricing
ProtonVPN offers a completely free plan with no data limits — the best free VPN tier available. The Plus plan costs $4.99/month on the 2-year plan and includes all servers, streaming support, and Secure Core. The Proton Unlimited plan ($7.99/month for 2 years) bundles all Proton services.
Usability
ProtonVPN's apps are clean and well-designed with a modern aesthetic. The server map provides a visual way to select connections, and the Profiles feature lets you save preferred configurations. The apps clearly indicate server load and support for streaming, P2P, and Secure Core, making server selection informed and easy.

Who should skip this
ProtonVPN is not the right pick for every reader. Skip it if:
- You want the absolute fastest speeds regardless of policy stance. Lightway on ExpressVPN and NordLynx often edge ahead.
- You need a mature family-plan structure bundled with privacy tools beyond VPN.
- You want a free tier that removes all limits. Proton's free tier is honest but intentionally limited.
