ProtonVPN is a virtual private network service created by Proton Technologies AG, the same Swiss company known for ProtonMail. Launched with a focus on privacy and security, ProtonVPN aims to give users stronger online anonymity, protection on public Wi‑Fi, and the ability to bypass geographic restrictions while keeping data under Swiss jurisdiction. Key features that define ProtonVPN include a strict no-logs policy, strong encryption, and a suite of privacy-oriented technologies. Connections use AES-256 encryption with modern key exchange and authentication algorithms, and the apps support secure VPN protocols such as WireGuard and OpenVPN. ProtonVPN also offers Secure Core — a multi-hop routing option that routes traffic through privacy-friendly countries before it exits to the internet — designed to protect against sophisticated network-based attacks. One of ProtonVPN’s distinguishing elements is transparency. The client apps are open source, and the company has commissioned independent security audits of its software and infrastructure. Based in Switzerland, Proton benefits from strong privacy laws and is outside the jurisdiction of the Five Eyes alliance, which appeals to users who prioritize legal protections for their data. ProtonVPN provides tiered plans, including a free version with limited server access and slower speeds compared to paid tiers. Paid plans expand available countries, enable streaming and P2P servers, allow simultaneous connections, and include features like Tor over VPN and advanced server routing. While the free tier is a useful entry point, heavy users — particularly those who stream high-definition video or need consistent P2P performance — will likely prefer one of the paid subscriptions. In practice, ProtonVPN performs well in privacy and security tests and is a solid choice for users who want a trustworthy VPN backed by a reputable company. Speeds on premium servers are competitive, though multi-hop routing and long-distance connections can reduce throughput, which is typical of privacy-enhancing VPN configurations. Its usability is strong: apps are available for Windows, macOS, Linux, iOS, and Android, and the interface balances simplicity with advanced options for power users. Considerations before choosing ProtonVPN include cost relative to other premium VPNs, occasional speed trade-offs for extra privacy modes, and geographic server coverage compared with some competitors that maintain larger global networks. For privacy-conscious users, journalists, or anyone tied to the Proton ecosystem (such as ProtonMail users), ProtonVPN is an attractive, credible option. In summary, ProtonVPN blends robust encryption, transparent practices, and privacy-oriented features under Swiss jurisdiction. Its free tier makes it accessible for casual users, while paid plans add performance and advanced capabilities for those who require more.
