proton vpn provides comprehensive network security protection
ProtonVPN's unique Secure Core technology routes traffic through privacy-protecting countries (Iceland, Switzerland, Sweden) before reaching target websites. Even if VPN servers are compromised, your real IP remains safe. Secure Core achieves double encryption through multi-hop routing. The first hop encrypts at privacy-protecting country servers, the second hop completes final encryption at destination country servers. This architecture ensures even if exit servers are breached, attackers cannot trace back to your real IP address. Swiss law strictly protects user privacy, not subject to EU data retention laws.
Built-in NetShield filter automatically blocks ads, trackers, and malware. Plus users can enable NetShield Level 2 to block all tracking scripts, improving browsing speed by 50%. NetShield filters at DNS level without additional plugins. Level 1 blocks ads, trackers and known malicious domains; Level 2 additionally blocks all tracking scripts and mining scripts. Test data shows enabling NetShield improves page load speed by 30-50%, saving approximately 2GB traffic monthly.
Each connection generates independent encryption keys. Even if long-term keys are compromised, historical sessions remain secure. ProtonVPN uses ECDHE key exchange for absolute session security. Perfect Forward Secrecy (PFS) is implemented through Diffie-Hellman key exchange protocol. Each VPN connection negotiates temporary session keys used only for current session. Keys are destroyed immediately after session ends. Even if attackers obtain server's long-term private key, they cannot decrypt past captured encrypted traffic.
ProtonVPN supports Windows, Mac, iOS, Android, Linux, Android TV and all major platforms. A single account supports 10 simultaneous device connections. Windows client supports Win 7/8/10/11; macOS client supports 10.13+ with native Apple Silicon support; iOS client supports 12.0+; Android client supports 6.0+; Linux client supports Ubuntu, Debian, Fedora. All clients are open-source and subject to community review.
ProtonVPN supports app-level split tunneling. Specify which apps go through VPN tunnel and which connect directly. Split Tunneling allows fine-grained control over network traffic routing. Windows and Android clients support per-app split tunneling with customizable rules. This feature protects privacy while avoiding network performance loss, especially suitable for business users needing simultaneous intranet and internet access.
All ProtonVPN servers support P2P traffic with no speed limits. Swiss privacy law protects your file sharing activities. ProtonVPN maintains friendly P2P traffic policies: all servers allow BitTorrent without bandwidth restrictions. Recommended P2P-friendly server nodes include Netherlands, Germany, Canada. Plus users enjoy 10Gbps server bandwidth for faster large file downloads.
