If you are in an environment where you want to make sure that the SSL VPN portal page does NOT show that is fine. You can use the following command to disable the SSL VPN Portal page of a FortiGate
Config VPN SSL Settings
Set sslvpn-enable disable
This is commonly used when you are wanting to accept only IPSec tunnels etc to your device. I usually just leave mine up and customize the page to look cool and creative but that is me!
