ProtonVPN is a virtual private network service built by the team behind Proton Mail. Launched with privacy as its core principle, ProtonVPN is headquartered in Switzerland — a jurisdiction with strong privacy laws — and emphasizes transparency, independent audits, and open-source client apps. Key features - No-logs policy: ProtonVPN states it does not log user activity or connection metadata that could be used to identify individual users. This posture is reinforced by Swiss privacy protections. - Secure Core: A distinctive multi-hop design routes traffic through privacy-friendly countries (often Switzerland, Iceland, or Sweden) before it exits to the wider internet. Secure Core improves resistance to network-level surveillance and correlation attacks. - Protocol support: ProtonVPN supports modern protocols, including WireGuard for fast, efficient connections, as well as OpenVPN and IKEv2 for broader compatibility. - NetShield: Available on paid plans, NetShield blocks trackers, ads, and malware at the DNS level to reduce privacy leaks and speed up browsing. - Tor integration: ProtonVPN operates Tor over VPN servers, allowing easy access to the Tor network for anonymity without separately configuring Tor software. - Kill switch and split tunneling: These protections prevent accidental data leaks by forcing traffic through the VPN and letting users choose which apps use the tunnel. Plans and performance ProtonVPN offers a free tier with access to a limited number of servers and medium speeds — a solid option for basic privacy needs. Paid plans add higher speeds, more server locations, Secure Core access, and features like NetShield and support for streaming or P2P. Performance is generally competitive, particularly when using WireGuard on nearby servers; however, Secure Core will add latency because of the multi-hop routing. Security and transparency ProtonVPN’s apps are open source and have undergone security audits, supporting its trust claims. Strong encryption, modern authentication, and the company’s Swiss base provide meaningful privacy advantages. Still, users should evaluate whether a VPN suits their threat model: a VPN conceals traffic from local networks and ISPs but does not anonymize you like Tor for higher-risk situations. Use cases and tips ProtonVPN is well suited for privacy-conscious users, journalists, and anyone wanting to protect browsing on public Wi‑Fi. For best results: use WireGuard on a nearby server for speed, enable the kill switch, and turn on NetShield if you want ad/tracker blocking. Choose Secure Core only when you need extra protection and can accept slower speeds. Conclusion ProtonVPN stands out for its privacy-first philosophy, innovative Secure Core multi-hop routing, and transparent practices. Its mix of free and paid plans makes it accessible, while modern protocols and privacy features make it a reliable choice for safeguarding everyday online activity.
