ProtonVPN is a virtual private network service developed by the team behind Proton Mail. Built with a strong emphasis on privacy and transparency, ProtonVPN aims to give users secure, easy-to-use tools to protect their internet traffic from surveillance, tracking, and interference. Headquartered in Switzerland, the company benefits from strong privacy laws and positions itself as a privacy-first alternative in the crowded VPN market. Core features set ProtonVPN apart. Secure Core is ProtonVPN’s multi-hop routing option that sends traffic through privacy-friendly servers in Switzerland, Iceland, or Sweden before it exits to the wider internet. This makes tracking the origin of connections substantially more difficult and helps defend against network-based attacks. ProtonVPN also supports modern VPN protocols such as WireGuard and legacy options like OpenVPN and IKEv2, giving users both strong performance and compatibility across devices. Privacy protections are central to ProtonVPN’s pitch. The service operates a no-logs policy and publishes transparency reports. Its apps are open-source, which allows independent review of the client software. ProtonVPN has undergone third-party audits to validate aspects of its security and privacy claims, and its team frequently communicates updates and improvements to the community. Security features commonly expected in a premium VPN are included: a kill switch to block traffic if the VPN connection drops, DNS leak protection, and secure encryption standards. ProtonVPN’s NetShield feature acts as a DNS-based blocker that can filter ads, trackers, and known malware domains, improving privacy and sometimes speeding up browsing. For users who want to access the Tor network without running the Tor Browser, ProtonVPN offers a Tor over VPN option that routes traffic into the Tor network from within the app. Performance and usability have improved significantly with support for WireGuard, which provides lower latency and higher throughput compared with older protocols. ProtonVPN operates a global network of servers, including specialized servers for P2P file-sharing and streaming. While VPNs cannot guarantee access to every streaming library or circumvent all forms of content restriction, ProtonVPN is commonly used to access geo-restricted content and to secure streaming on untrusted networks. ProtonVPN is available on major platforms — Windows, macOS, Linux, iOS, and Android — and provides browser extensions and manual configuration options for routers. It offers a free tier with limited speeds and server access, which is useful for casual users or those who want to try the service before upgrading. Paid plans add features like Secure Core, higher speeds, more simultaneous connections, and access to the full server network. Typical use cases for ProtonVPN include protecting privacy on public Wi-Fi, avoiding ISP tracking, secure remote access, and maintaining anonymity while browsing. As with any VPN, users should weigh their threat model and needs; ProtonVPN is best suited for people prioritizing privacy, transparency, and strong technical safeguards. Overall, ProtonVPN is a robust choice for users seeking a privacy-focused, audited, and feature-rich VPN solution.
