Company Mac OS laptop must connect to Cisco AnyConnect VPN in order to access to the Internet

My company Mac OS X laptops (Mojave) are managed devices and in order for the user to connect to Internet, the user must first launch and connect the Cisco AnyConnect VPN otherwise the user is not able to connect to the Internet.

Just for my knowledge, I am looking for the specific file or configuration profile or settings that show me this specific rule. It must be something on the system that I can see that the Mac system must be connected to Cisco AnyConnect VPN first in order to get Internet access.

I just want to see where this rule is located.
