ProtonVPN is a privacy-focused virtual private network service developed by Proton AG, the Swiss company behind Proton Mail. Designed with an emphasis on security and transparency, ProtonVPN aims to give users safer, more private internet access whether they are on public Wi-Fi, at home, or traveling. Its combination of strong encryption, a clear privacy policy, and a range of modern VPN features makes it a popular choice for privacy-conscious users. One of ProtonVPN’s defining features is its Secure Core architecture. Secure Core routes traffic through multiple servers in privacy-friendly countries before it exits to the public internet, which helps protect against network-based attacks and makes it harder to trace user activity back to an origin IP. The service also supports modern VPN protocols such as WireGuard, along with OpenVPN and IKEv2, providing a good balance between speed and security. Standard features include AES-256 encryption, a network-wide kill switch, DNS leak protection, and optional split tunneling on supported platforms. ProtonVPN offers both a free tier and several paid plans. The free plan is notable for providing a usable level of service without data caps (subject to connection speeds and server availability), which is rare among reputable providers. Paid tiers add access to more servers, faster speeds, streaming-optimized and P2P-friendly servers, and advanced features like Tor over VPN. Pricing and plan details change over time, but the company positions its paid packages to cater to casual users, power users, and privacy advocates alike. Cross-platform compatibility is strong: ProtonVPN provides apps for Windows, macOS, Linux, Android, and iOS, along with setup guides for routers and other devices. The apps are generally user-friendly, with quick-connect options for beginners and detailed configuration settings for advanced users. Performance tends to be reasonable, especially on WireGuard-enabled servers, though speeds can vary depending on server load and geographic distance. From a privacy standpoint, ProtonVPN benefits from being headquartered in Switzerland, which has robust privacy laws and is outside US and EU surveillance alliances. The company has repeatedly emphasized a strict no-logs policy and transparency in its operations. Prospective users should still review current audits and privacy statements to confirm the latest status and any independent verifications. ProtonVPN is well-suited for people who prioritize privacy, want a reputable free option, or need features like Secure Core and Tor integration. It’s also a solid choice for streaming or torrenting when using the appropriate servers. Users seeking the absolute cheapest service or maximum global server count may find other providers more appealing, but for many, ProtonVPN’s mix of security, simplicity, and principled privacy stance makes it a strong contender in the VPN market.
