ProtonVPN is a privacy-focused virtual private network developed by the team behind ProtonMail. Based in Switzerland — a country with strong privacy laws — ProtonVPN places user confidentiality at the forefront, combining technical safeguards, transparent policies, and easy-to-use apps for desktop and mobile platforms. Core features and security At the heart of ProtonVPN’s offering are modern encryption standards and secure protocols. The service supports WireGuard and OpenVPN, using AES-256 encryption and robust key exchange mechanisms to protect traffic. ProtonVPN’s Secure Core architecture routes traffic through multiple privacy-friendly servers (located in Switzerland, Iceland, and Sweden) before it exits to the public internet, making it much harder for adversaries to trace the origin of a connection. Additional features include a strict no‑logs policy, a network kill switch that prevents data leakage if a connection drops, DNS leak protection, and optional Tor over VPN for seamless access to the Tor network. Privacy, transparency, and trust ProtonVPN emphasizes transparency: the apps are open source and regularly audited, and the company publishes transparency reports and warrants canaries. Being headquartered in Switzerland gives ProtonVPN legal protections that limit the scope for government data requests compared with many other jurisdictions. Combined with independent audits, these factors enhance trust for users prioritizing privacy. Plans and performance ProtonVPN offers a free tier with limited countries and medium speeds — a useful option for basic privacy needs. Paid plans unlock faster servers, support for WireGuard, Secure Core, streaming-optimized servers, P2P-friendly servers, and higher simultaneous device allowances. Performance is generally competitive: WireGuard connections deliver low-latency, high-throughput speeds suitable for streaming and large downloads. Server distribution is wide enough for most needs, though extremely large server farms of some competitors may deliver slightly better global coverage. Use cases - Privacy-conscious browsing and defending against ISP tracking. - Secure access to public Wi‑Fi hotspots without risking man-in-the-middle attacks. - Streaming geo-restricted content via dedicated streaming servers. - Safe P2P/torrenting on P2P-enabled servers. - Combining ProtonMail and ProtonVPN for enhanced privacy across email and web traffic. Pros and cons Pros: Strong privacy focus, Swiss jurisdiction, Secure Core, open-source apps, audited code, free plan. Cons: Paid plans can be pricier than some competitors, and server count is moderate rather than massive. Getting started Sign up at the ProtonVPN website, choose a plan (or start free), download the app for your device, log in, and connect to a server.

In summary, ProtonVPN is an excellent choice for users who prioritize privacy, transparency, and security, offering a balance of powerful features and accessible apps suitable for both novices and advanced users.#1#
