ProtonVPN is a virtual private network developed by Proton AG, the same Swiss company behind Proton Mail. It aims to provide strong privacy and security protections while remaining easy to use for both beginners and experienced users. Based in Switzerland, ProtonVPN benefits from favorable privacy laws and a stated no-logs policy that minimizes the data stored about users’ online activity. Key features - Strong encryption and modern protocols: ProtonVPN supports WireGuard, OpenVPN, and IKEv2, and uses industry-standard encryption (AES-256) to protect your traffic. - Secure Core: This unique feature routes traffic through multiple privacy-friendly countries (for example: Switzerland, Iceland) before reaching the public internet. Secure Core is useful when you want an extra layer of protection against network-level surveillance. - Tor over VPN: ProtonVPN can route traffic through the Tor network directly from the app, allowing easier access to .onion sites and an additional privacy layer without a separate Tor browser setup. - Kill switch and leak protection: Built-in features prevent DNS, IPv6, and WebRTC leaks and block internet access if the VPN connection drops. - Cross-platform apps and audited code: ProtonVPN offers apps for Windows, macOS, Linux, iOS, and Android, with some components open-source and subject to third-party audits. - Free tier and paid plans: ProtonVPN has a free plan with limited servers and speeds, plus tiered paid plans that add faster servers, Secure Core, streaming and P2P-optimized servers, and multi-device support. Why choose ProtonVPN ProtonVPN is a solid choice if privacy and transparency matter to you. Its Swiss jurisdiction, public commitment to no-logs, and emphasis on open technologies make it appealing to privacy-conscious users. Secure Core and Tor-over-VPN options set it apart from many competitors for higher-risk use cases. Use cases - Secure public Wi‑Fi: Encrypts traffic on untrusted networks in cafés, airports, and hotels. - Privacy-first browsing: Masks your IP and reduces tracking by websites and advertisers. - Geo-unblocking: Access region-restricted content on streaming platforms (performance varies by server). - Safe P2P: Offers torrent-friendly servers on paid plans. Practical tips - For best speed, select a nearby server; use WireGuard when available for an optimal balance of speed and security. - Enable the kill switch and DNS leak protection in the app settings. - Use Secure Core only when you need extra privacy; it can reduce speed because of extra routing. - Keep apps updated and review the plan that meets your device and bandwidth needs. Conclusion ProtonVPN combines strong technical safeguards with a privacy-centric company background. It’s flexible enough for everyday security and advanced enough for users who require additional anonymity protections. As with any VPN, match features and performance to your needs and test the service using the free tier or trial before committing to a subscription.
