Secure Core
Proton VPN''s Secure Core architecture gives our secure VPN service the unique ability to defend against network-based attacks. Secure Core protects your connection by routing your traffic through multiple servers before leaving our network. This means an advanced adversary who can monitor the network traffic at the exit server will not be able to discover the true IP address of Proton VPN users, nor match browsing activity to that IP.
Secure core servers are located in hardened data centers in Switzerland, Iceland, and Sweden, protected by strong privacy laws, and operated on our own dedicated networks.
Adblocker (NetShield)
NetShield is a DNS filtering feature that protects you from malware, blocks ads, and prevents website trackers from following you as you surf the web.
VPN Accelerator
VPN Accelerator is a set of technologies unique to Proton VPN that can increase your VPN speeds by over 400%. By overcoming CPU limitations that affect how VPN protocols are processed, using advanced networking techniques to reduce latency, and redesigning VPN protocols themselves to reduce inefficiencies in their code, VPN Accelerator can dramatically increase speed performance.
Forward Secrecy
We have carefully selected our encryption cipher suites to only include ones that have Perfect Forward Secrecy. This means that your encrypted traffic cannot be captured and decrypted later if the encryption key from a subsequent session gets compromised. With each connection, we generate a new encryption key, so a key is never used for more than one session.
Strong Protocols
We use only VPN protocols that are known to be secure - OpenVPN, IKEv2, and WireGuard. Proton VPN does not have any servers that support PPTP and L2TP/IPSec, even though they are less costly to operate. By using Proton VPN, you can be confident that your VPN tunnel is protected by the most reliable protocol.
Strong Encryption
We use only the highest strength encryption to protect your Internet connection. This means all your network traffic is encrypted with AES-256, key exchange is done with 4096-bit RSA, and HMAC with SHA384 is used for message authentication.
Full Disk Encryption
Although virtually no personally identifiable data is stored on them anyway, all Proton VPN servers are protected by full disk encryption. This helps secure them from resource-intensive man-in-the-middle attacks of the kind that can be performed by governments. Full disk encryption secures server certificates and all other configurations and software stored on an exit server, so that even if the server is somehow compromised, attackers would not be able to access any data stored on it.
Anonymous
We respect your privacy so no personal identifying information is required to obtain a Proton VPN account. You can sign up with an anonymous Proton Mail email account and use our anonymous VPN without disclosing your identity.
High Speed
For optimal performance, we use only high-speed servers. All Proton VPN servers have at minimum 1 Gbps bandwidth, and many of our servers also utilize 10 Gbps connections. This means that even though we utilize only the strongest encryption, Proton VPN also provides blazing fast speeds.
Easy to Use
We understand that it is important for security technology to be easy to use. We have designed the Proton VPN applications to have a simple and intuitive user interface so that browsing privately and anonymously can be done with a single click. Additionally, you can create custom connection profiles which automatically protect your device whenever you connect to the internet.
