ProtonVPN is a virtual private network service developed by Proton AG, the same Swiss company behind ProtonMail. It positions itself as a privacy-first VPN, emphasizing strong encryption, transparent policies, and protections that reduce the risk of surveillance and data collection. Headquartered in Switzerland—known for robust privacy laws—ProtonVPN appeals to users who want a legally grounded privacy solution combined with practical features for everyday browsing, streaming, and file sharing. Security and privacy lie at the heart of ProtonVPN’s offering. The service supports modern VPN protocols such as WireGuard, OpenVPN, and IKEv2, and uses AES-256 encryption with secure key exchange to protect data in transit. ProtonVPN has implemented features that harden user privacy beyond standard VPN functionality: Secure Core routes traffic through hardened servers in privacy-friendly countries before it exits to the wider internet, reducing the risk from compromised exit nodes. Tor over VPN lets users route traffic to the Tor network with a single click. A strict no-logs policy, backed by independent security audits and transparency reports, underpins the service’s privacy claims. ProtonVPN is available across major platforms—Windows, macOS, Linux, Android, iOS—and offers manual configuration options for routers and other devices. Core privacy features include a kill switch (which prevents leaks if the VPN connection drops), DNS leak protection, and split tunneling on supported platforms. The network also supports P2P traffic on selected servers and maintains specialized servers for streaming and high-bandwidth activities. Performance has improved significantly with the adoption of WireGuard, which generally provides faster and more stable connections than older protocols. ProtonVPN operates hundreds of servers across multiple countries; paid subscribers gain access to the full server network, faster speeds, and advanced features like Secure Core and Plus-only servers optimized for streaming and P2P. ProtonVPN also offers a limited free tier—useful for casual users who want VPN protection without cost—though the free plan has fewer server locations and lower priority speeds. While ProtonVPN is a strong choice for privacy-conscious users, potential downsides include the need to subscribe for the fastest speeds and full feature set, and occasional variability in streaming unblocking depending on the service and region. Overall, ProtonVPN is a compelling option for users who value transparency, strong technical protections, and a company structure rooted in privacy-friendly jurisdiction.
