Intelligent application protection from edge to cloud with Azure Web Application Firewall

Threat intelligence at scale!


Changes to how we work and operate our businesses have driven every company to now be a digital company. This acceleration in digital transformation has also led to a rise in security risks. Cyberattacks are becoming more common and advanced with growing attack surfaces due to the proliferation of mobile and IoT devices and increasing cloud adoption. Basic protection measures are no longer sufficient as new attack vectors have emerged and attacks have become more sophisticated with automated and large-scale attacks. To help our customers address these security challenges, we have been evolving Azure Web Application Firewall (Azure WAF), our cloud-native, self-managed security service to protect your applications and APIs running in Azure or anywhere else—from the network edge to the cloud.


A quick primer on Azure WAF

We offer two options—global and regional—for deploying Azure WAF for your applications and APIs.




  • Global WAF: Azure WAF attaches to Azure Front Door, our native, modern cloud content delivery network (CDN), to provide global application acceleration and intelligent security at scale. Azure WAF stops the security attacks at the network edge closer to the source of attack with over hundreds of edge locations around the world.


  • Regional WAF: Azure WAF attaches to Azure Application Gateway, a highly scalable, web application regional load balancer running in a virtual network. It manages traffic for both internal and external websites and provides application protection in over 60 Azure regions worldwide.
