ProtonVPN Free
What we liked
- Truly unlimited data — no caps or throttling
- No-logs policy backed by Swiss privacy law
- Strong encryption (AES-256, OpenVPN, WireGuard)
- Built by the same team as Proton Mail
- Kill switch and DNS leak protection
- No ads, no bandwidth selling
Could be better
- Only 1 device
- Only 3 server locations (US, Netherlands, Japan)
- No streaming or torrenting support on free plan
- No access to Secure Core or Tor servers
- Medium speeds due to server crowding
Best for security-first users. ProtonVPN Free is the only genuinely unlimited free VPN with a verified no-log policy and Swiss privacy protection. If you need privacy without data caps, this is it.
