ProtonVPN is a privacy-focused virtual private network developed by Proton AG, the Swiss company best known for ProtonMail. Designed to give users secure, private access to the internet, ProtonVPN combines strong encryption, modern protocols, and privacy-preserving features to protect data on public Wi‑Fi, prevent tracking, and help bypass content restrictions. Core features and privacy protections ProtonVPN uses industry-standard encryption and modern VPN protocols, including WireGuard, OpenVPN, and IKEv2. WireGuard support offers a compelling balance of strong security and high performance, making it a good choice for streaming and large downloads. The service implements DNS leak protection and an automatic kill switch that blocks internet access if the VPN connection drops, preventing accidental exposure of your real IP address. A standout ProtonVPN feature is Secure Core, a multi-hop architecture that routes your traffic through privacy-friendly countries before it leaves Proton’s network. This adds an extra layer of protection against network-based attacks or adversaries who might try to trace traffic back to the user. ProtonVPN also offers Tor over VPN servers, enabling direct access to the Tor network without a separate Tor Browser configuration for added anonymity when needed. Transparency and trust ProtonVPN is based in Switzerland, a jurisdiction known for strong privacy laws, which is an important advantage for users concerned about governmental data requests. The company has emphasized transparency and privacy in its operations: its VPN apps are open-source, allowing independent review of client code, and the service has undergone security reviews. Proton’s public-facing approach and its broader reputation in privacy services reinforce its trustworthiness in the VPN market. Performance and usability ProtonVPN provides a range of plans, including a limited free tier and paid subscriptions that unlock higher speeds, more server locations, and advanced features like Secure Core and NetShield. NetShield is an integrated ad and malware blocker that filters trackers, ads, and malicious domains at the DNS level, improving privacy and browsing speed. Apps are available for Windows, macOS, Linux, Android, iOS, and compatible routers, with user-friendly interfaces and features like split tunneling on supported platforms. Use cases Common use cases include securing devices on public Wi‑Fi, avoiding ISP tracking, accessing home country content while traveling, and maintaining anonymity for sensitive communications. While ProtonVPN can help bypass geo-blocking and censorship in many cases, users in highly restricted regions should combine it with safe practices and consider additional tools as needed. Conclusion ProtonVPN is a strong option for users who prioritize privacy and transparency without sacrificing performance. With Swiss jurisdiction, open-source clients, Secure Core multi-hop routing, and modern protocols like WireGuard, it provides a well-rounded suite of features for personal and professional privacy needs.
