Proton VPN is a Swiss-based VPN service built by the team behind Proton Mail, with 8,600+ servers worldwide. All apps are open-source and independently audited. It offers a free tier with unlimited data and no ads, making it one of the few trustworthy free VPN options. Swiss jurisdiction provides strong legal privacy protections.
Proton VPN benefits from the trusted Proton brand and ecosystem bundling with Mail, Drive, Calendar, and Pass. It competes with Mullvad on privacy credentials, mainstream VPNs like NordVPN and ExpressVPN on features, and Windscribe on flexible pricing. The free tier is a major acquisition channel that few competitors match.
Anonymous signup with no email required and cash payments. Simpler and more privacy-focused but no free tier and smaller server network.
Largest mainstream VPN with 6,000+ servers and aggressive marketing. Threat Protection feature blocks ads and malware. More commercially oriented than Proton's privacy focus.
Unique build-a-plan pricing at $1/location/month. R.O.B.E.R.T. ad and tracker blocking. Free tier with generous data but Canada-based (Five Eyes alliance).
Known for consistently fast speeds and reliability. Premium pricing with strong streaming support. Less transparent about privacy than Proton's open-source approach.
