Proton VPN review — the privacy-first pick

Many free VPNs fund service through advertising or data collection. Proton VPN instead offers a limited free tier alongside paid plans, and that model is one reason it ranks highly in this review. It comes from the team behind Proton Mail, publishes open-source apps, and supports its no-logs policy with independent audits under Swiss law.

Documented protection#

Proton documents kill-switch, DNS-leak protection, and Secure Core features. Secure Core routes traffic through an additional server before it exits. These controls can reduce common leak and traffic-correlation risks, but their effectiveness depends on the application, platform, configuration, and threat model.

Performance#

Proton supports WireGuard and publishes platform-specific applications. Actual connection speed depends on the selected server, route, device, and network, so readers should test the service on their own connection before relying on it for demanding workloads.

Privacy#

This is where Proton earns its ranking. The apps are open-source and auditable, the no-logs policy has been verified by outside assessors, and the company's Swiss jurisdiction keeps it out of reach of the usual data-sharing alliances.

Verdict#

Proton VPN is the VPN we recommend first: trustworthy where it counts, fast enough for everything, and backed by the only free tier we're comfortable telling people to use.
