How does SSL VPN work in FortiGate?

SSL VPN (Secure Sockets Layer Virtual Private Network) in FortiGate is a type of VPN that uses SSL/TLS encryption protocols to create a secure and encrypted connection between the user’s device and the internal network resources.

When a user wants to access an internal resource, they connect to the SSL VPN gateway through a web browser or a client application installed on the device. The SSL VPN gateway then authenticates the user’s credentials and creates a secure SSL/TLS encrypted tunnel between the user’s device and the internal network.

This encrypted tunnel allows the user to access the internal resources securely, as all the data transmitted between the user’s device and the internal resources are encrypted and protected from eavesdropping and other cyber threats.

Furthermore, FortiGate SSL VPN has several features that enhance security, such as two-factor authentication, endpoint detection and response, and antivirus scanning.

To uninstall FortiGate SSL VPN, users can follow the standard process for uninstalling applications on their operating system. However, it is recommended to consult the Fortinet documentation or seek assistance from a certified Fortinet technician before uninstalling any FortiGate component to ensure proper removal and avoid potential system issues.
