ProtonVPN is a virtual private network service developed by Proton AG, the same team behind ProtonMail. Built around privacy-first principles, ProtonVPN aims to provide strong encryption, transparent operations, and user-friendly apps for desktop and mobile platforms. Headquartered in Switzerland — a country known for robust privacy laws — ProtonVPN emphasizes legal protections and a no-logs policy to minimize the amount of data that can be accessed by third parties. Key features ProtonVPN supports modern VPN protocols including WireGuard, IKEv2, and OpenVPN, offering a balance between performance and security. Its Secure Core architecture routes traffic through privacy-friendly countries (such as Switzerland and Iceland) before exiting to the public internet, adding an extra layer of protection against network-based attacks and surveillance. The service also provides built-in protections like a kill switch, DNS leak prevention, split tunneling (on some platforms), and optional Tor over VPN for an extra layer of anonymity when accessing the Tor network. Privacy and transparency ProtonVPN publishes transparency reports and has taken steps toward openness by making many of its apps open-source and subject to independent security audits. The company’s Swiss location is frequently highlighted because Swiss law favors strong data protection, and the no-logs policy means ProtonVPN states it does not store browsing activity or connection logs that could identify users’ online behavior. Plans and usability ProtonVPN offers a free tier that provides limited server access and moderate speeds — a useful option for users who want basic privacy without a subscription. Paid plans add access to the full server network, higher-speed connections, Secure Core servers, streaming and P2P-optimized servers, and additional simultaneous device connections. Native apps are available for Windows, macOS, Linux, iOS, and Android, and the interface is generally considered intuitive for both beginners and experienced users. Performance and limitations With WireGuard enabled, ProtonVPN can deliver competitive speeds suitable for streaming, video calls, and large downloads; however, actual performance depends on server load and geographical distance. While ProtonVPN’s Secure Core enhances privacy, routing traffic through multiple hops can introduce additional latency, so it’s best used when privacy outweighs speed concerns. Some users may also find the range of server locations smaller than that of very large competitors, although ProtonVPN focuses on strategically chosen locations and security-minded infrastructure. Who should consider ProtonVPN ProtonVPN is a strong choice for privacy-conscious users who value transparency and a strong legal framework. It’s suitable for journalists, activists, travelers, and everyday users who want to protect their data on public Wi‑Fi, access geo-restricted content, or reduce tracking. As with any VPN, evaluate features, performance, and price against your needs, and consider trying the free plan or short-term subscription to assess compatibility and speed before committing.
