ProtonVPN is a virtual private network service developed by Proton AG, the same team behind ProtonMail. Launched with privacy as its core mission, ProtonVPN emphasizes strong technical protections, transparent practices, and user control. Its Swiss base gives it favorable data-protection legal conditions and a firm public commitment to a strict no-logs policy. Core features that define ProtonVPN include robust encryption and modern VPN protocols. The service supports WireGuard, IKEv2, and OpenVPN, offering a balance between speed and security. ProtonVPN also implements a system-wide kill switch and DNS leak protection to prevent accidental exposure of user traffic if a connection drops. For users seeking extra anonymity, ProtonVPN’s Secure Core routes traffic through multi-hop servers in privacy-friendly countries before reaching the internet, protecting against network-level attackers. ProtonVPN also provides specialty features for different needs. NetShield is an integrated DNS-based blocker that filters ads, trackers, and known malware domains at the DNS level, improving privacy and sometimes speed. The service supports Tor over VPN, enabling direct access to the Tor network without a separate Tor Browser configuration. Peer-to-peer traffic is allowed on selected servers, and ProtonVPN’s higher-tier plans include access to high-speed servers optimized for streaming and torrenting. One attractive aspect is ProtonVPN’s availability: it offers apps for Windows, macOS, Linux, Android, and iOS, plus configuration guides for routers. ProtonVPN maintains an openly visible stance on transparency—clients and some server-side components have been audited and aspects of the software are open source, allowing independent review of security claims. Plans range from a free tier with limited servers and speeds to paid plans that unlock the full server network, Secure Core, faster protocols like WireGuard, and additional features such as dedicated IPs and priority support. The free option is useful for casual users or those who want to test the service, while paid tiers are designed for frequent streamers, heavy downloaders, and privacy-focused professionals. In practice, ProtonVPN is well-suited for users who prioritize privacy guarantees, want a Swiss-based provider, or need advanced features like multi-hop routing and Tor integration. It also performs strongly for general VPN tasks—securing connections on public Wi‑Fi, accessing geo-restricted content, and maintaining anonymity online. Limitations include potential speed trade-offs on certain Secure Core or long-distance connections and restricted free-tier resources. As with any VPN, the choice should be based on your threat model, performance needs, and feature priorities. For those seeking a privacy-centric, transparent VPN with modern protocols and specialty privacy tools, ProtonVPN is a compelling option.
