ProtonVPN is a virtual private network service developed by the team behind Proton Mail. Built around a privacy-first philosophy, ProtonVPN aims to give users secure, private access to the internet by encrypting traffic, masking IP addresses, and routing connections through a global server network. Its legal base in Switzerland adds an extra layer of protection because Swiss privacy laws are among the strongest in the world. Security and privacy are core selling points. ProtonVPN supports modern, high-performance protocols such as WireGuard and OpenVPN, and uses industry-standard encryption (AES-256 with strong key exchange and perfect forward secrecy). The company states a strict no-logs policy, meaning it does not record users’ browsing activity. In addition to its policy, ProtonVPN’s apps and code are open source and have undergone independent security audits, which help validate its claims and reduce the risk of hidden vulnerabilities. Unique features set ProtonVPN apart from many competitors. Secure Core is a multi-hop architecture that routes traffic through privacy-friendly countries before it leaves Proton’s network, making correlation attacks and simple exit-server tracking more difficult. NetShield is an integrated DNS-level blocker that can block ads, trackers, and malware domains, improving privacy and reducing unwanted content. ProtonVPN also supports Tor over VPN, allowing users to route traffic to the Tor network with a single click for added anonymity. ProtonVPN is available in several tiers, including a free plan that provides access to a small selection of servers and limited speeds — useful for casual users or those who want to test the service. Paid plans unlock faster speeds, access to the full server network, Secure Core, streaming-optimized servers, P2P support on selected servers, and other advanced features. Apps are available for Windows, macOS, Linux, Android, and iOS, and ProtonVPN can be configured on compatible routers for whole-network protection. Performance is generally solid, especially on WireGuard, though actual speeds depend on server load, location, and the user’s internet connection. ProtonVPN’s emphasis on privacy sometimes means trade-offs (for instance, Secure Core routes can be slower because traffic passes through multiple hops), but for users prioritizing anonymity and strong legal protections, these trade-offs are intentional and valuable. In summary, ProtonVPN is a robust option for users who want a privacy-respecting VPN backed by strong encryption, Swiss jurisdiction, and a suite of advanced privacy features. Its combination of open-source apps, independent audits, and specialized features like Secure Core and NetShield make it a compelling choice for privacy-conscious users.
