Protocoles VPN

Nos protocoles de tunneling VPN sécurisés

PrivateVPN prend en charge les protocoles VPN les plus courants. Si vous utilisez une appli VPN, paramétrez-la pour qu'elle sélectionne automatiquement le protocole VPN qui convient le mieux à votre réseau. Si vous n'utilisez pas d'application ou si vous n'aimez pas la connexion, apprenez la différence entre les protocoles VPN et essayez les protocoles suivants dans l'ordre de la liste ci-dessous.

Protocole OpenVPN 

OpenVPN is your first choice. OpenVPN permits various kinds of authentication methods and utilizes a secure SSL/TLS protocol for key exchange. OpenVPN provides the fastest vpn protocol access speed compared to L2TP, but it is not supported on all devices.

OpenVPN UDP vs TCP

OpenVPN over TCP, or Transmission Control Protocol, is the most reliable VPN connection type. Using error correction, this connection prevents website failure and incomplete downloads by automatically retransmitting information packets during data transfer.

OpenVPN over UDP, or User Datagram Protocol, is usually faster than TCP because it lacks the error correction feature. Web technologies that depend on real-time interaction, such as online gaming, work better without the interruptions caused by data retransmission.

L2tp VPN and IPsec VPN

You can layer 2 VPN protocols with L2TP and IPsec. When used in combination L2TP and IPsec offer greater security than PPTP, but these protocols are slower than OpenVPN and can be blocked by firewalls on occasion.

L2TP, or Layer 2 Tunneling Protocol, was developed as an upgrade to L2F (Layer 2 Forwarding Protocol) and PPTP (Point-to-Point Tunneling Protocol). By itself, L2TP does not offer very strong authentication or encryption, which is why it is used together with the IPsec protocol. L2TP is ideal for use with mobile devices that are not compatible with OpenVPN.

IPsec, or Internet Protocol security, authenticates and encrypts each IP information packet in a communication, offering a high level of end-to-end security. IPsec offers protection for all application traffic over an IP network and is available for most mobile devices.

WireGuard

WireGuard provides the latest cryptography alongside extreme speed. With very little overhead WireGuard —  above existing technologies —  offers the opportunity for a more simple, secure, and efficient protocol for VPN use.
