ProtonVPN is a consumer and business VPN service developed by Proton AG, the company behind Proton Mail. Designed around privacy and security, it emphasizes a no-logs policy, strong encryption, and transparency. Based in Switzerland — a country with robust privacy laws — ProtonVPN aims to provide users with a trustworthy option for safeguarding online activity, evading tracking, and accessing geo-restricted content. Key features - Strong encryption and modern protocols: ProtonVPN supports WireGuard and OpenVPN, providing a balance of speed and security. Connections use industry-standard cryptography to protect traffic and maintain confidentiality. - No-logs policy and Swiss jurisdiction: ProtonVPN states it does not log user activity. Being headquartered in Switzerland places it outside the 14 Eyes intelligence-sharing alliance and under Swiss privacy legislation. - Diskless (RAM-only) servers: Many ProtonVPN servers run in RAM only, which helps ensure that data cannot be retained on disk if a server is seized or compromised. - Secure Core routing: This feature routes traffic through multiple servers in privacy-friendly countries before it exits to the public internet, adding protection against network-level attacks. - Tor over VPN: Users can route traffic directly to the Tor network from the ProtonVPN app without a separate Tor browser configuration, offering an extra layer of anonymity. - NetShield ad and malware blocking: Built-in DNS filtering blocks ads, trackers, and malicious domains at the network level. - Kill switch and leak protection: Apps include an automatic kill switch and protections against DNS and IPv6 leaks to prevent accidental exposure of real IP addresses. - Open-source apps and audits: ProtonVPN’s clients are open-source, and the service has engaged in third-party audits, supporting greater transparency. Plans and usability ProtonVPN offers a free tier with limited servers and moderate speed, which is useful for casual privacy needs or testing the service. Paid tiers (Plus and higher) unlock faster servers, Secure Core, streaming and P2P-optimized servers, and additional features. There’s also a Visionary plan that bundles ProtonVPN with Proton Mail for users who want full-suite privacy services. Apps and compatibility Native apps are available for Windows, macOS, Linux, Android, and iOS, and ProtonVPN can be configured on compatible routers. Features like split tunneling are available on some platforms, while the user interface focuses on simplicity for newcomers and enough control for advanced users. Who should use it ProtonVPN is a strong choice for privacy-conscious users, journalists, and anyone who wants a credible no-logs VPN with transparent practices and extra privacy layers like Secure Core and Tor integration. The free plan makes it accessible for initial use, while paid plans are competitive for users seeking higher speeds and additional security features.#1#

PN: A Privacy-Focused VPN from Switzerland Keywords ProtonVPN, VPN, privacy, Secure Core, WireGuard, no-logs, Switzerland, Proton Description ProtonVPN is a privacy-centric virtual private network developed by the same team behind ProtonMail. It emphasizes strong encryption, a strict no-logs policy, and unique features such as Secure Core routing to protect users’ anonymity and data. Content ProtonVPN is a consumer VPN service designed for people who prioritize privacy and security. Launched by the creators of ProtonMail, it is headquartered in Switzerland, which benefits from strong privacy protections and data-friendly legal frameworks. The service aims to combine strong technical safeguards with transparent policies and user-friendly apps across desktop and mobile platforms. Security and privacy are at the center of ProtonVPN’s offering. The service uses industry-standard encryption and supports modern VPN protocols including OpenVPN, IKEv2, and WireGuard. ProtonVPN enforces a strict no-logs policy, meaning it states it does not record user traffic or connection logs. To further harden privacy, ProtonVPN includes DNS leak protection, a kill switch that blocks internet access if the VPN connection drops, and full-disk encrypted servers in some configurations. A standout feature is Secure Core, which routes traffic through multiple servers in privacy-friendly countries (such as Switzerland and Iceland) before it exits to the public internet. This multi-hop architecture reduces the risk that an adversary could trace traffic back to a user even if an exit server were compromised. ProtonVPN also publishes transparency reports and has undergone third-party security audits, adding credibility to its privacy claims. ProtonVPN offers several subscription tiers, including a limited free plan. The free tier provides access to a small set of servers with moderate speeds, making it useful for casual or privacy-conscious users on a budget. Paid plans unlock faster speeds, access to the full server network, Secure Core, streaming and P2P-optimized servers, and advanced features like split tunneling and dedicated IP addresses. Pricing is competitive, especially if you bundle VPN service with Proton’s other privacy products. Performance is generally good, particularly when using WireGuard, which is designed for speed and efficiency. However, real-world speeds can vary by server location and network conditions. ProtonVPN’s network size is smaller than some major commercial providers, so peak-time congestion can be a factor for some users. ProtonVPN is a solid choice for users who value privacy, transparency, and independent audits. It’s particularly well-suited for journalists, activists, and everyday users who want a trustworthy VPN backed by a privacy-focused company. For people whose primary need is maximum streaming performance or the largest global server footprint, other providers might offer advantages. Overall, ProtonVPN provides a balanced blend of security, usability, and a
