Azure Function & VNet Integration
It allows the function app to access resources in a VNet without exposing them to the internet. It’s useful for securing outbound traffic from the function app.

This ensures that all outbound traffic from FA uses specific static public IP addresses --> Control Azure Functions outbound IP with an Azure virtual network NAT gateway | Microsoft Learn
Security : VNet Integration helps in securing FA by allowing it to communicate with resources in VNet privately.
