What's the difference between an NSG and Azure Firewall ?

Hi,

Thank you for posting the question to the Q&A forum.

Unlike Azure Firewall, which monitors all traffic for workloads, NSG is commonly deployed for individual vNets, subnets, and network interfaces for virtual machines to refine traffic. It does so by activating a rule (allow or deny) or Access Control List (ACL), which allows or denies traffic to Azure resources.
