WAF comparison
Azure WAF vs AWS WAF
Compare Azure Web Application Firewall and AWS WAF for cloud-native application protection across Azure and AWS workloads.
WAFWiki verdict
Choose Azure WAF for Azure Front Door or Application Gateway paths. Choose AWS WAF for CloudFront, ALB, API Gateway, AppSync, and AWS-native workloads.
Search intent: Cloud security team comparing WAF options across Azure and AWS architectures.
| Area | Azure Web Application Firewall | AWS WAF | WAFWiki note |
|---|---|---|---|
| Cloud fit | Azure Front Door and Application Gateway | CloudFront, ALB, API Gateway, and AppSync | The strongest fit follows the cloud entry point. |
| Operations | Azure policy, diagnostics, and Microsoft tooling | AWS web ACLs, rule groups, sampled requests, and AWS logging | Choose the platform your security team can monitor well. |
| Multi-cloud use | Best for Azure-fronted traffic | Best for AWS-fronted traffic | A neutral edge WAF may be simpler for applications spanning several clouds. |
How to validate this choice
- Deploy each option in the same traffic path where possible.
- Replay representative clean and malicious requests.
- Track blocked requests, false positives, latency, and operational effort.
- Compare rollback steps and logging integrations before production use.
Scientific comparison rule
A WAF comparison is only meaningful when traffic path, rule mode, test payloads, and observation window are consistent. WAFWiki uses this principle to guide future benchmark pages.
Azure Web Application Firewall
Azure Web Application Firewall is a managed WAF option for Azure-hosted and Azure-fronted applications, especially when teams already use Application Gateway or Azure Front Door.
