ProtonVPN is a virtual private network developed by Proton AG, the Swiss company best known for ProtonMail. Designed with privacy and security as priorities, ProtonVPN aims to give users a safer, more open internet experience by encrypting traffic, masking IP addresses, and routing connections through privacy-conscious infrastructure. One of ProtonVPN’s defining features is its jurisdiction: headquartered in Switzerland, it benefits from strong privacy laws and is outside the direct reach of U.S. or EU intelligence-sharing agreements. The service maintains a strict no-logs policy and has made its apps open-source, allowing independent reviewers to inspect the code. ProtonVPN has also subject its applications and infrastructure to third-party security audits, reinforcing trust in its claims. Security-wise, ProtonVPN supports modern protocols such as WireGuard, OpenVPN, and IKEv2, offering fast, secure tunnels suitable for various devices. Advanced options include a system-wide kill switch to prevent data leakage if the VPN disconnects, DNS leak protection, and Secure Core — a feature that routes traffic through Proton’s hardened servers in privacy-friendly countries before exiting to the wider internet. Secure Core adds an extra layer of defense against network-level surveillance and targeted attacks. Beyond privacy, ProtonVPN offers practical features: NetShield (an ad and tracker blocker) on paid plans, Tor over VPN for seamless access to the Tor network, designated P2P servers for torrenting, and optimized servers for streaming and gaming. Apps are available for Windows, macOS, Linux, Android, iOS, and certain router setups, making it easy to protect multiple devices. ProtonVPN provides a free tier with access to a limited number of servers and moderate speeds, useful for basic privacy needs or testing the service. Paid plans expand server access, unlock Secure Core, offer higher speeds, and add features like NetShield. Pricing is competitive with tiered options for individuals and families. Performance is generally solid, particularly with WireGuard, though actual speeds depend on server choice and location. ProtonVPN’s focus on privacy can make some Secure Core routes slower than standard connections, so users should balance privacy needs and speed requirements. Who should consider ProtonVPN? Privacy-conscious users, journalists, activists, and anyone wanting a reputable VPN backed by transparent practices and a strong legal jurisdiction. For casual users who prioritize streaming only, cheaper or more speed-focused alternatives might be worth comparing. Overall, ProtonVPN is a well-rounded, privacy-centric VPN that combines robust security features with user-friendly apps and a free option — a strong choice for users who put privacy first.
