ProtonVPN is a virtual private network service developed by Proton AG, the Swiss company best known for Proton Mail. Built around privacy-first principles and headquartered in Switzerland — a country with strong privacy laws — ProtonVPN aims to give users secure, private, and transparent internet access without compromising ease of use. Core features and security ProtonVPN offers strong encryption (AES-256) and supports modern VPN protocols including WireGuard, OpenVPN, and IKEv2. WireGuard is the default for many users because of its balance of speed and security. ProtonVPN apps are open-source and have undergone independent security audits, which improves trust by allowing third parties to review the code. A standout feature is Secure Core, which routes traffic through multiple servers in privacy-friendly countries (such as Switzerland and Iceland) before exiting to the public internet. This architecture helps mitigate risks from compromised exit servers and increases resilience against advanced network surveillance. ProtonVPN also includes a built-in kill switch, DNS leak protection, and optional Tor over VPN access for routing traffic directly into the Tor network. Privacy and transparency ProtonVPN maintains a strict no-logs policy and benefits from Swiss jurisdiction, which offers legal protections that can make it harder for outside governments to obtain user data. The company publishes transparency reports and has a history of defending user privacy. While no provider can guarantee absolute anonymity, ProtonVPN’s combination of technical features and legal positioning makes it a solid option for privacy-conscious users. Plans, platforms, and performance ProtonVPN offers a free tier with limited server access and moderate speeds, useful for casual or trial use. Paid tiers (Plus, Visionary, and others) unlock Secure Core, higher speeds, more server locations, P2P-optimized servers for torrenting, and streaming-optimized servers for services like Netflix and BBC iPlayer. Apps are available for Windows, macOS, Linux, Android, and iOS, plus manual setup options for routers and other devices. Performance varies by server choice and location; WireGuard generally provides the best speeds, while Secure Core adds privacy at the cost of some latency. For typical browsing, streaming, and secure remote access, ProtonVPN delivers reliable performance. Who should consider ProtonVPN? Choose ProtonVPN if you want a privacy-minded, transparent VPN with strong legal protections, open-source clients, and advanced features like Secure Core and Tor integration. If your priority is the absolute fastest speeds for gaming or downloading large files, test the paid plans and select servers optimized for performance. In summary, ProtonVPN is a well-rounded VPN service that balances privacy, transparency, and usability — particularly attractive for users who treat online privacy as a high priority.
