Protecting Proton VPN’s infrastructure

We protect your data with only the strongest encryption. We also go to great lengths to protect Proton VPN’s physical infrastructure.

  • We own, ship, and install our Secure Core servers ourselves.
  • Our servers are housed in secure data centers with biometric security.
  • All VPN servers have full-disk encryption to secure their server certificates.
  • Multiple layers of VPN security

    Your security is our primary concern, which is why we consider and address every potential vulnerability in our VPN service. To keep your data as secure as possible, we house our critical infrastructure in highly secure locations and limit access to our VPN servers to approved partners.

    Secure locations

    Our critical infrastructure, like our Secure Core VPN servers, is housed in secure data centers or on former military bases. Using these locations prevents anyone from being able to tamper with our servers.

    Limited access

    We installed all our Secure Core infrastructure and operate it ourselves to prevent anyone from gaining unauthorized access to our servers. These extra security precautions prevent our hardware from being compromised or tampered with.

    Full-disk encryption

    Full-disk encryption secures our server certificates, configurations, and other software, so even in the unlikely event that someone was able to get physical access to one of our VPN servers, they would not be able to access its encryption keys.

    Keep your connection secure with Proton VPN

    DNS leak protection

    Your DNS queries can be analyzed to see what websites you visited. To prevent this, we include your DNS queries in the encrypted VPN tunnel and run our own DNS servers. This ensures your DNS queries are resolved without ever exposing your browsing activity.

    Kill switch

    Our built-in kill switch feature continuously monitors your connection to our VPN servers and will immediately block all network traffic if you lose your connection to the VPN server. By blocking all traffic, the kill switch feature prevents your true IP address from being revealed.

    Tor over VPN

    If you have a Plus plan, you can use Proton VPN to access the Tor network. Route all your traffic through the Tor anonymity network and access onion sites with a single click using our Tor-enabled VPN servers.

    Frequently Asked Questions

    How do you protect my data?

    Proton VPN protects your data at every level. To begin with, we require no personally identifying information when you sign up for an account — just an email address. We only use the strongest encryption and VPN protocols for your internet traffic, including IKEv2, OpenVPN, and WireGuard, and we protect our servers with full-disk encryption. Additionally, our infrastructure is housed on ex-military bases and in secure data centers to prevent unauthorized physical access.

    Where is Proton VPN based?

    Proton VPN is based in Switzerland. This means that in addition to our strong physical security, we are also protected by some of the world’s strictest privacy laws. Switzerland’s strong laws mean that we cannot be coerced into spying on anyone, and we are not obligated to save any user connection logs.

    Who owns Proton VPN?

    Proton VPN was created by the same team of scientists that met at CERN who developed Proton Mail, the respected end-to-end encrypted email service. Proton VPN employees hold the vast majority of shares in the company, and we are almost entirely financed by our paying subscribers, so we have no incentive to betray our community’s privacy or trust.

    Does a Proton VPN Free plan compromise my security in any way?

    No. If you have a Proton VPN Plus plan, you will receive additional features, but using a Free plan does not compromise your privacy or security in any way. If you sign up for a Proton VPN Free plan, you will receive the same level of encryption and privacy.
