These are hypothetical scenarios with explicit assumptions. They do not establish equal capabilities, measured usability or a negotiated price.
| Requirement | Proposed exercise | Accept when |
|---|---|---|
| Legitimate requests | Run the application's representative safe requests through the test policy. | Required user actions remain available. |
| Test rule | Exercise a safe request designed to match a disposable rule. | The selected policy records or handles the request as configured. |
| False-positive review | Inspect policy events for a representative test session. | The team can explain and resolve unexpected matches. |
| Policy rollback | Rehearse restoration of the previous approved policy. | The operator can reverse an unintended policy change. |

Scope and architecture
Azure WAF and AWS WAF have different policy objects and supported attachment points. Compare the complete application delivery deployment, rule management and false-positive handling rather than assuming managed rule names are identical.
A web application firewall is one layer of application security. Its integration point, managed-rule scope and custom policies must fit the actual application and do not replace secure application code or access control.

Cost and migration planning
For Azure Web Application Firewall, include selected deployment, policies and related application edge resources. For AWS WAF, include web ACLs, rules, requests and selected managed capabilities. Use the same workload and resilience assumptions, then confirm current vendor terms for the selected configuration.
Start with a non-blocking or controlled test configuration where the selected product supports it. Exercise legitimate application requests and safe test payloads, then review false positives and the rollout process before enforcing a production policy.
