ProtonVPN is a virtual private network service developed by Proton AG, the Swiss company best known for Proton Mail. Built around privacy and open principles, ProtonVPN aims to provide secure, reliable internet access while minimizing data exposure to third parties. Its approach combines strong encryption, a transparent development model, and a legal advantage from being headquartered in Switzerland — a country with robust privacy protections. Core features of ProtonVPN include end-to-end encryption using modern protocols, support for WireGuard and OpenVPN, and a strict no-logs policy. WireGuard offers a lightweight, high-performance connection with contemporary cryptography, while OpenVPN remains a widely supported and configurable option. ProtonVPN’s clients are open source, allowing independent inspection of their code — an important factor for users who need verifiable assurances about how their traffic is handled. One distinctive aspect of ProtonVPN is Secure Core. This feature routes user traffic through multiple secure servers in privacy-friendly jurisdictions (for example, Switzerland, Iceland, and Sweden) before it exits to the wider internet. Secure Core makes it substantially harder for observers to correlate incoming and outgoing traffic, adding a layer of protection for users at elevated risk. Additional security features include a reliable kill switch, DNS leak protection, Tor-over-VPN support, and split tunneling on supported platforms. ProtonVPN offers both free and paid plans. The free tier provides access to a limited set of servers and is suitable for casual users who want basic protection without cost. Paid tiers expand server access, add access to Secure Core, higher connection speeds, P2P-optimized servers for torrenting, and advanced streaming support. ProtonVPN Plus is positioned for power users, offering the fastest servers and priority support. Pricing is competitive with other reputable VPNs, and Proton frequently emphasizes its commitment to not monetizing user data. Performance is generally strong, particularly when using WireGuard and connecting to nearby servers. As with any VPN, speeds vary by server load, distance, and local network conditions, but many reviewers and users find ProtonVPN fast enough for streaming, gaming, and large downloads on premium plans. ProtonAG also publishes transparency reports and has undergone independent security audits, bolstering its credibility. In summary, ProtonVPN is a solid choice for privacy-conscious users who want a transparent, well-engineered VPN with strong Swiss legal protections. It balances ease of use with advanced options for those who need enhanced anonymity or specialized configurations. Whether you choose the free plan or a paid subscription, ProtonVPN provides reliable tools to reduce online tracking and improve digital security.
