ProtonVPN is a privacy-centric virtual private network (VPN) developed by Proton AG, the Swiss company best known for Proton Mail. It aims to combine strong technical protections with user-friendly apps so individuals and businesses can browse, stream, and communicate with greater confidentiality and security. Core privacy and jurisdiction ProtonVPN benefits from Switzerland’s strong privacy laws and outside-the-EU/US jurisdiction, which can provide an added legal layer of protection for user data. Proton states a strict no-logs policy — meaning it does not record user activity — and its applications are open-source and have undergone independent security audits, which increases transparency and trust. Security technologies ProtonVPN supports modern VPN protocols such as WireGuard and OpenVPN, delivering a good balance of speed and cryptographic robustness. Unique to ProtonVPN is the “Secure Core” feature: traffic first routes through privacy-friendly servers in secure countries (like Switzerland and Iceland) before exiting through a public server. This multi-hop approach defends against network-level surveillance and malicious exit nodes. Other useful protections include a reliable kill switch, DNS leak protection, Tor over VPN, and NetShield — an optional built-in tracker and ad blocker that can also block malware and ads at the DNS level. Performance and streaming With WireGuard and well-distributed servers, ProtonVPN generally offers competitive speeds suitable for streaming, video calls, and downloads. Paid plans unlock higher-speed servers optimized for streaming and torrenting and increase the number of simultaneous connections. ProtonVPN can unblock many popular streaming services, though success can vary by region and streaming provider. Plans and platform support ProtonVPN provides a free tier with limited countries and medium speeds, which is a strong option for casual users who want basic privacy without cost. Paid tiers (Basic, Plus, and Visionary) add features like Secure Core, faster servers, more simultaneous connections, and advanced threat protection. Official apps are available for Windows, macOS, Linux, iOS, Android, and select routers, with user-friendly interfaces and advanced settings for power users. Considerations No VPN can guarantee absolute anonymity. Users should combine ProtonVPN with good security practices (strong passwords, 2FA, careful browsing). Pricing is higher than some budget providers but reflects Proton’s focus on privacy, open-source software, and independent audits. Conclusion ProtonVPN is a solid choice for users prioritizing privacy and transparency. Its Swiss base, audited apps, Secure Core multi-hop routing, and modern protocols make it particularly appealing to journalists, activists, or anyone seeking stronger protection than typical consumer VPNs.
