ProtonVPN is a virtual private network service designed around privacy, transparency and security. Launched by the ProtonMail team, the company is headquartered in Switzerland, a jurisdiction known for robust privacy laws. That legal base underpins its core selling points: a strict no-logs policy, independent audits, and a commitment to open-source clients and clear privacy practices. Security and privacy features are central to ProtonVPN’s appeal. Connections use modern protocols and strong cryptography (AES-256, 4096-bit RSA where applicable, and ChaCha20/IETF for WireGuard), and the service supports multiple secure tunneling options including OpenVPN and WireGuard. ProtonVPN offers a “Secure Core” architecture — traffic is routed through privacy-friendly countries and Proton’s hardened servers before exiting to the wider internet — reducing risks from certain types of surveillance or compromised exit nodes. Additional protections include a built-in kill switch, DNS leak protection, and full-disk encrypted servers. ProtonVPN supports a range of use cases. It allows P2P file sharing on select servers and offers optimized streaming servers to access geo-restricted content. A free tier is available, which is unique for a privacy-focused provider: it gives access to a limited set of servers with moderate speeds and no data cap, making it useful for testing and basic browsing. Paid plans add access to the full server network, faster speeds, Secure Core, Tor over VPN, and support for more simultaneous connections. Proton’s Visionary or Plus plans also include perks for ProtonMail users, so the service can integrate into a broader privacy stack. Apps are available for Windows, macOS, Linux, iOS and Android, plus configuration guides for routers. The clients are generally user-friendly, with simple connect buttons for beginners and advanced settings for power users. Performance has improved over time, particularly with the adoption of WireGuard, though speeds vary by server and location like any VPN service. On the downside, premium pricing is higher than some mainstream competitors, and advanced privacy features require higher-tier plans. The free plan is limited, and not every server supports every use case (for example, P2P is restricted to specific servers). Overall, ProtonVPN is a strong choice for users who prioritize privacy, transparency and security. Its Swiss jurisdiction, Secure Core routing, audited no-logs policy and open-source clients make it especially appealing to privacy-conscious individuals, while the range of apps and features keeps it accessible to general users seeking better online privacy.#1#
