ProtonVPN is a VPN service from Proton AG, the Swiss company behind Proton Mail. It routes internet traffic through encrypted servers to protect privacy and bypass network restrictions, operating under a strict no-logs policy backed by Swiss privacy law. Unusually among VPN providers, its free tier has no data cap or ads, though it limits server locations and speed compared to paid plans.
Why ProtonVPN's Free Tier Stands Out
Most "free" VPNs cap monthly data, show ads, or quietly sell usage data to stay in business. ProtonVPN's free plan instead offers unlimited data with no ads, funded by its paid subscribers, though it restricts users to a smaller set of server countries and standard, not top, speeds. Its Secure Core feature, available on paid plans, routes traffic through privacy-friendly countries before it exits to the public internet.
ProtonVPN Features
- Free Tier with No Data Cap — unlimited data usage on the free plan, unusual among free VPN services

- WireGuard and OpenVPN Support — modern, fast VPN protocols alongside the established OpenVPN standard
- Secure Core Servers — routes traffic through hardened servers in privacy-friendly countries before exiting to the internet

- NetShield — built-in blocking of ads, trackers and known malicious domains
- Cross-Platform Apps — dedicated apps for Windows, macOS, Linux, Android and iOS

Avoid third-party "download manager" sites offering ProtonVPN. They commonly wrap the genuine installer in their own bundler, which is how adware and browser hijackers get onto a machine that the user believed was clean.
