Secure Core is ProtonVPNโs multi-hop architecture designed to fortify your online privacy by routing traffic through privacy-friendly countries before it exits to the public internet. By leveraging Secure Core servers located in Switzerland, Iceland, and Sweden, you gain an extra layer of defense against network-based attacks and potential surveillance. ๐
๐ What Is Secure Core
Secure Core consists of hardened VPN servers hosted in privacy-safe jurisdictions. When you connect, traffic first enters a Secure Core server, then passes through a second VPN server close to your location. This double-hop arrangement makes it extremely difficult for adversaries to trace your real IP or monitor your activities.
๐ Why Choose Secure Core
โ Enhanced anonymity: Two separate VPN hops conceal your origin.โ Protection against compromised servers: Even if an exit server is attacked, the Secure Core server safeguards your true IP.โ Jurisdictional advantage: Entry servers are hosted in countries with strong privacy laws (Switzerland, Iceland, Sweden).

โ๏ธ Performance Considerations
Latency Speed
Due to the extra hop, latency can increase by 20โ50 ms. Download/upload speeds typically remain above 60โ70% of your baseline, depending on your location.
Bandwidth Impact
Secure Core servers are provisioned with high bandwidth, but if you experience slowdowns, switch to the nearest Secure Core exit server for optimal performance.
๐ก๏ธ Troubleshooting Tips
โ Connection fails Verify your subscription tier supports Secure Core.โ Persistent timeouts Switch DNS to 1.1.1.1 or 9.9.9.9 in Settings โ Network.โ Crashes on startup Reinstall the latest ProtonVPN version and reboot.
