Secure Core VPN safeguards your data

ProtonVPN’s Secure Core network gives your data an additional layer of security and defends you against advanced attacks.

  • Protect yourself from advanced network attacks
  • Remain secure behind two layers of encryption
  • Connect to our most secure VPN servers
  • How Secure Core defends your data

    We installed our Secure Core servers(new window) and continue to operate them ourselves to eliminate any chance that they could be tampered with, and all Secure Core VPN servers are located in countries with strong data privacy laws. ProtonVPN’s Secure Core routes your traffic through these hardened servers before connecting you to a second VPN server. With Secure Core, if the other VPN server is somehow compromised, your online traffic and IP address remain safe.

    Global server network

    Route your traffic through our Secure Core servers in privacy-friendly countries — Switzerland, Iceland, or Sweden — to any of our VPN servers in dozens of countries around the world.

    Full-disk encryption

    All ProtonVPN Secure Core servers have full-disk encryption, which secures all the software and certificates in an exit server. So even if an attacker somehow got physical access to a server, they still would not be able to access its encryption keys.

    High-security data centers

    Our Secure Core servers are owned and operated by ProtonVPN and are stored in high-security data centers that follow strict security protocols. This level of security reduces the risk that anyone could have tampered with or compromised these servers.

    A secure and reliable VPN

    Always-on VPN

    ProtonVPN’s always-on VPN feature automatically establishes a connection between your device and the server, ensuring you remain protected at all times.

    Kill switch

    If your connection to one of our VPN servers is interrupted, the kill switch automatically blocks all connections to your device, so your IP address is never exposed to the network outside the secure VPN tunnel.

    DNS and IPv6 leak protection

    ProtonVPN guards against two common issues: DNS and IPv6 leaks. Your DNS queries are always resolved on our DNS servers, and we convert all IPv6 traffic into a protocol that won’t expose your device’s IP address.

    Frequently Asked Questions

    Is ProtonVPN trustworthy?

    ProtonVPN was created by Proton, the same company that built ProtonMail, the world’s largest encrypted email service. As a company founded by scientists, we believe that trust must be verified by data. This is why we have made all our apps open source and are open about who we are.

    Proton’s vision is to create an internet where privacy is the default, and we are supported by the European Commission and recommended by the United Nations. We support the global movement for online freedom and privacy and have donated over $500,000 to organizations whose work aligns with our mission.

    What is ProtonVPN’s Secure Core VPN?

    Secure Core VPN refers to ProtonVPN’s network of specially protected servers that are located in three privacy-friendly countries: Switzerland, Iceland, and Sweden. It is an advanced security feature that improves your security and privacy. By routing your traffic through our Secure Core servers before reaching the exit server in another country, you add an extra layer of security between your data and any attacker monitoring the network.

    Is Secure Core safe?

    Yes, ProtonVPN’s Secure Core feature is designed to make surveillance exceedingly difficult. As for the Secure Core servers themselves, we use full-disk encryption and house them in high-security data centers. We own and provision all of these servers ourselves.
