About Proton VPN
Proton VPN, from the creators of Proton Mail, brings Swiss-level privacy to the VPN market. Operating under Switzerland's strict privacy laws — widely considered the strongest in the world — Proton VPN offers a level of legal protection that few competitors can match. Their Secure Core architecture routes traffic through multiple servers in privacy-friendly countries before exiting, making it extremely difficult to trace activity back to the user. The free plan is genuinely impressive: no data caps, no ads, and the same strong encryption as paid plans. While speeds on the free tier are limited, paid plans offer excellent performance with WireGuard support and access to servers in 65+ countries.

Final Verdict
Proton VPN is the best choice for privacy purists who value transparency and legal protection above all else. The free plan is genuinely useful and makes Proton VPN accessible to everyone. While the premium plans are pricier than some competitors and lack live chat support, the combination of Swiss jurisdiction, open-source code, and Secure Core architecture makes it the most trustworthy VPN available.
