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.

Secure Core VPN

Our Secure Core architecture gives you extra security against advanced attacks by routing your traffic through multiple servers before it leaves our network.
