It would be cool to have examples on where to use one. I am aware of the capabilities but a NSG is a simple firewall that can be attached to a VNET. If you do not need SNAT, DNAT or Layer 7 you can use NSG. There is a question the the practice exam which I choose the wrong alternative since it is does not require specific features which I could use with a Firewall.

Hi Fernando,
Thanks for the feedback. I have noted it and will take it into account in the next round of updates. 😊

An NSG is a firewall, albeit a very basic one. It’s a software defined solution that filters traffic at the Network layer. However, Azure Firewall is more robust. It’s a managed firewall service that can filter and analyze L3-L4 traffic, as well as L7 application traffic.
