What is a Next-Generation Firewall?
Why Next-Generation Firewalls are important
As increasing numbers of organizations began using (and depending on) online applications and SaaS services, it became clear that simply inspecting ports and protocols was insufficient to provide effective network security. The most significant innovation at the time was the ability to provide Layer 7 application profiling and IPS, enabling highly granular policy enforcement based on specific applications.
NGFWs are by now a mature solution category. However, the ongoing mass migration of IT workloads to public-cloud IaaS platforms such as Amazon Web Services, Microsoft Azure, and Google Cloud Platform — and the resulting increase in the complexity of hybrid network architectures — is driving a push to expand the capabilities of advanced network firewalls yet again. In this case, to provide advanced traffic management, WAN optimization, quality-of-service, and transparent cloud-platform integration.
