6 core features designed to protect your online privacy and data security
ProtonVPN is headquartered in Geneva, Switzerland, governed by Swiss Federal Data Protection Act. Switzerland is not part of EU/US intelligence sharing agreements, legally prohibiting mandatory data retention.
All proton vpn client code is open-source on GitHub, regularly audited by independent security firms like Securitum. Zero-log policy verified multiple times, audit results publicly available.
6000+ servers across 112 countries, all 100% physical servers (no virtual). Stable low-latency connections. Every data center passes strict security review.
protonvpn Secure Core is an industry-unique double VPN feature. Your traffic first passes through an entry server in Switzerland, Iceland or Sweden for first-layer AES-256 encryption, then relays to the exit server in the target country for second-layer encryption.
Even if the exit server is compromised, attackers only see encrypted traffic from the Swiss relay server, unable to trace back to your real IP. This architecture is crucial for journalists, activists and users requiring maximum privacy.
NetShield is proton vpn's built-in DNS-level security engine that analyzes and blocks threats before data packets reach your browser. Three filtering levels: Level 1 blocks malware and ads, Level 2 additionally blocks trackers, Level 3 provides complete domain filtering.
Tests show page load speed improves by 30% with NetShield enabled, blocking over 120,000 tracker requests monthly. For users frequently visiting unsafe sites, NetShield provides native protection without additional browser plugins.
When VPN connection drops unexpectedly, protonvpn's Kill Switch cuts all network traffic within milliseconds, preventing real IP and unencrypted data leaks. System-level implementation means even if the VPN process crashes, network is fully blocked.
Unlike application-layer detection solutions, proton vpn Kill Switch directly controls traffic routing through the OS network stack, ensuring no "naked" moments. Network auto-restores after VPN reconnection, no manual operation needed.
proton vpn provides native clients for Windows, macOS, Linux, Android, iOS with unified interface design. Each client is deeply optimized for its platform: Windows system tray shortcuts, macOS menu bar quick connect with Apple Silicon native support.
Android supports Always-On VPN for continuous background protection, iOS supports Widget and Siri voice control. protonvpn also provides CLI tool protonvpn-cli for Linux servers and advanced users. Single account connects up to 10 devices.
protonvpn is one of few VPN providers with native Tor support. Any VPN server connects directly to Tor network without installing Tor Browser. Triple onion routingε ε VPN encryption provides double anonymity.
Access .onion sites as easily as regular web pages, one-click toggle within the client. For maximum anonymity, Tor over VPN ensures even if Tor entry nodes are monitored, they only see encrypted traffic from VPN servers, completely untraceable to your real identity.
proton vpn dedicated Streaming servers are route-optimized for Netflix, Disney+, BBC iPlayer, Hulu and other mainstream platforms. Smart routing algorithm auto-matches best nodes for 4K UHD zero-buffering playback.
