Which types of VPNs does FortiGate support?

FortiGate supports two primary types of VPNs: IPsec and SSL. This capability allows organizations to implement secure site-to-site connections using IPsec, which is ideal for connecting different networks securely, and remote user access via SSL, which allows secure connections for users working remotely from various locations.

IPsec is a robust and widely used protocol that offers strong encryption and is suitable for connecting entire networks together. It operates at the network layer and secures and authenticates IP packets. On the other hand, SSL (Secure Sockets Layer), now largely replaced by TLS (Transport Layer Security), provides secure access for individual users and is particularly useful for remote access VPNs, where end-user flexibility and ease of use are essential.

While other protocols like PPTP and L2TP may provide VPN services, FortiGate does not primarily support them in the context of the latest capabilities for secure connections. Specifically, PPTP has known security vulnerabilities, making it less favorable for deployment in secure environments. L2TP often relies on IPsec for encryption but is not directly included as a separate type of VPN within FortiGate's conventional offerings.

Hence, the combination of IPsec and SSL VPNs fully leverages the security features FortiGate provides,
