ProtonVPN is a popular virtual private network developed by Proton AG, the Swiss company behind Proton Mail. Built around privacy and transparency, it aims to give users secure, private Internet access without logging or selling data. Switzerland’s strong privacy laws and Proton’s clear no-logs policy are central selling points for privacy-conscious users. Security and privacy features ProtonVPN supports modern VPN protocols including WireGuard, OpenVPN, and IKEv2. WireGuard is the default choice for many users because of its combination of strong cryptography and high performance. ProtonVPN also implements a system-wide kill switch to prevent leaks if the VPN connection drops, DNS leak protection, and optional split tunneling on supported apps. A standout feature is Secure Core: traffic is routed through privacy-friendly countries (such as Switzerland, Iceland, or Sweden) before exiting to the public Internet. This adds an extra layer of protection against network-level surveillance or compromised exit servers. ProtonVPN also provides built-in ad, tracker, and malware blocking via NetShield, and access to Tor over VPN by connecting to special Onion servers. Apps, audits, and transparency ProtonVPN offers apps for Windows, macOS, Linux, Android, and iOS, and supports configuration on many routers. The clients are open-source, which enables community scrutiny, and Proton has a history of third-party security audits—details of these audits are published on their site for transparency. Performance and use cases With WireGuard and a large global server network, ProtonVPN can deliver competitive speeds suitable for streaming, remote work, and general browsing. Paid plans unlock priority servers optimized for streaming and P2P/Torrenting, and tend to perform better under load. ProtonVPN is capable of unblocking many popular streaming services, though availability can change as services update restrictions. Pricing and plans ProtonVPN offers a free tier with limited locations and lower speeds, which is a solid option for casual users who want basic protection. Paid tiers (Basic, Plus, and higher/combined bundles) add faster connections, more server locations, Secure Core, NetShield, simultaneous connections, and integrations with ProtonMail in combined plans. Pros and cons summary Pros: strong privacy focus, Switzerland jurisdiction, Secure Core, open-source apps, free plan, WireGuard support, Tor servers. Cons: higher-priced top tiers compared with some competitors, Secure Core sometimes reduces speed due to double routing, and streaming/P2P performance depends on server choice. Conclusion ProtonVPN is a solid choice for users who prioritize privacy and transparency and want a trustworthy VPN backed by independent audits and a reputable company. The free tier and clear feature set make it easy to test before upgrading to a paid plan for better speeds and advanced features.
