ProtonVPN is a virtual private network service developed by the team behind Proton Mail, designed to provide strong privacy protections, modern security protocols, and a user-friendly experience. Based in Switzerland, ProtonVPN benefits from a legal framework with robust privacy laws, which complements its stated no-logs policy and commitment to user confidentiality. Security and privacy ProtonVPN supports industry-standard protocols such as WireGuard, OpenVPN, and IKEv2. WireGuard in particular offers a good balance of speed and security, reducing connection overhead without sacrificing encryption strength. ProtonVPN also provides features tailored to privacy-conscious users: a strict no-logs policy, Secure Core servers that route traffic through multiple privacy-friendly jurisdictions, and Tor over VPN integration that sends traffic directly into the Tor network for additional anonymity. A built-in kill switch prevents accidental IP leaks if the VPN connection drops, and DNS leak protection is enabled to keep queries private. Unique features Secure Core is a standout feature: rather than routing traffic through a single exit server, Secure Core first routes it through servers in high-privacy countries (such as Switzerland or Iceland) before exiting to the wider internet. This makes tracing user activity more difficult even if an exit server is compromised. NetShield, ProtonVPN’s ad and malware blocker, filters out trackers, ads, and known malicious domains at the DNS level, improving both privacy and browsing speed. ProtonVPN also offers split tunneling on supported platforms, allowing users to designate which apps use the VPN and which use the regular connection. Plans and accessibility ProtonVPN has a free tier with access to a limited subset of servers and moderate speeds, which is useful for basic privacy needs and for trying the service without commitment. Paid tiers add faster servers, access to Secure Core, more simultaneous connections, and additional country locations. The service provides apps for Windows, macOS, Linux, Android, and iOS, with browser extensions and clear setup guides for less technical users. Performance and use cases With modern protocols and a global server network, ProtonVPN performs well for everyday browsing, secure remote work, and streaming. Many users rely on it to protect sensitive communications on public Wi‑Fi, access region-restricted content, and maintain privacy from ISPs and advertisers. For those needing extra anonymity or anti-censorship tools, Secure Core and Tor over VPN are valuable options. Transparency and trust ProtonVPN emphasizes transparency: it publishes audits, transparency reports, and details about infrastructure and privacy practices. For users who want privacy without sacrificing usability, ProtonVPN offers a feature-rich, well-documented, and trustworthy option backed by a team with a long-standing focus on privacy.
