What Is ProtonVPN?
ProtonVPN is built by the Proton team — the same company behind ProtonMail. Headquartered in Switzerland (outside EU and US jurisdiction), it operates under some of the world's strictest privacy laws. The client apps are fully open-source and independently audited, which is rare among VPN providers and allows the privacy community to verify the no-logs claim in code.
The standout feature is the free tier: ProtonVPN Free gives unlimited data with no expiration and no payment required. Speeds are throttled on free, and server access is limited to 3 countries (US, Netherlands, Japan), but there is no data cap — making it the only serious option for users who need ongoing VPN access without paying.
Paid plans add 100+ server countries, Stealth protocol (obfuscation for restricted networks including China), Secure Core (multi-hop routing through Switzerland/Iceland/Sweden), and NetShield (DNS-level ad and malware blocking). For users who prioritize verifiable privacy over maximum speed, ProtonVPN is the strongest choice in the market.
