Understanding Cloud Firewalls

Cloud firewalls operate differently than traditional on-premises firewalls, largely due to their role in inspecting packets at various layers. They can exist as virtual appliances or as services from cloud providers like AWS and Azure. This differentiation means that organizations must navigate the complexities of cloud networking versus on-premise setups, where they often relied on hardware boxes. Given the intricacies of public cloud environments, understanding the functionality and capabilities of cloud firewalls becomes essential for effective network security.
