Hello @Tomy Alfida
Thanks for reaching out to Microsoft Q and A platform.
At this time WAF could be used along with these three Azure Resources:
· Application Gateway: What is Azure Web Application Firewall on Azure Application Gateway? - Azure Web Application Firewall | Microsoft Learn
· Azure Front Door: What is Azure web application firewall on Azure Front Door? | Microsoft Learn
· CDN: What is Azure web application firewall on Azure CDN? | Microsoft Learn
If you would like to use it along with Watchguard, then you must design the Infra as such we include the above resource as the multiple layers.
Regards,
Priya Kumar
