Which protocol does FortiGate typically use for VPN connections?

The protocol that FortiGate typically uses for VPN connections is IPsec. IPsec (Internet Protocol Security) is a suite of protocols designed to provide secure communication over an IP network by authenticating and encrypting each IP packet in a communication session.

Using IPsec allows FortiGate to create a secure tunnel between endpoints, ensuring that sensitive data can be transmitted safely across potentially insecure networks, such as the internet. IPsec supports various encryption and authentication algorithms, enabling organizations to implement the level of security required for their specific needs.

In the context of VPNs, IPsec is favored because it not only facilitates secure data transmission but also allows for the establishment of site-to-site and remote access connections. This versatility makes it an ideal choice for FortiGate appliances, which are designed to offer robust security solutions and enable secure remote access for users and devices.
