The VPN Advisor - ProtonVPN Review 2025 - Expert Analysis

ProtonVPN is backed by the same privacy-focused team behind ProtonMail, bringing Swiss privacy standards to the VPN industry. Operating from Switzerland, ProtonVPN benefits from some of the world's strongest privacy laws and offers both free and premium tiers. The service maintains over 1,800 servers across 66 countries, with a focus on security and privacy rather than sheer server count.

ProtonVPN employs military-grade encryption and operates under a strict no-logs policy that has been independently audited. The service offers unique features like Secure Core, which routes traffic through privacy-friendly countries before connecting to the final destination, providing an extra layer of protection against network attacks.

ProtonVPN supports WireGuard, OpenVPN, and IKEv2 protocols, ensuring compatibility across all devices. While their free tier offers genuine privacy protection with no data caps or ads, the paid tiers unlock high-speed servers, streaming support, and advanced features like Tor over VPN. With open-source apps, Swiss jurisdiction, and a commitment to transparency, ProtonVPN appeals particularly to privacy advocates and users in high-risk environments who need maximum security guarantees.
