Evaluation criteria

|---|---|
| Deployment model | Managed WAF tied to Azure application delivery entry points. |
| Operations | Best when Azure Monitor, diagnostics, and Microsoft tooling are already part of the workflow. |

Hands-on test plan
- Attach a WAF policy to one test Front Door or Application Gateway path.
- Run in detection mode and review diagnostics.
- Test login, upload, admin, and API workflows.
- Document exclusions, custom rules, and rollback to detection mode.
Decision questions
- Is the protected application already fronted by Azure services?
- Do we need Front Door WAF, Application Gateway WAF, or both?
