Can I Use WAF Across Enterprise Projects?

That depends on which mode your WAF instance is deployed. The details are as follows:

• Cloud mode
  • Cloud mode- CNAME access: In this mode, WAF can be used across enterprise projects.
  • Cloud mode - Load balancer access: In this mode, WAF can be used across enterprise projects only when the load balancer and WAF instance groups are in the same VPC.
• Dedicated mode

  If you dedicated WAF instance can communicate with the VPC where your origin servers belong, the instance can be used across enterprise projects. Otherwise, the WAF dedicated you purchase in a certain enterprise project cannot be used for other enterprise projects.

  

  For the dedicated WAF instance that cannot communicate with the VPC where your origin servers belong, if you still want to use it for other enterprise projects, go to the Enterprise Project Management page and move the WAF instance to the target enterprise project. Then, you can use or upgrade the dedicated WAF instance in the enterprise project.
