Our verdict on Azure Web Application Firewall
Azure Web Application Firewall is a managed web application firewall for organizations running applications on Azure. It protects websites and APIs from common web exploits, including SQL injection and cross-site scripting. The service supports edge deployment through Azure Front Door or regional protection through Application Gateway, with controls for managed rules, custom policies, bots, rate limits, IP access, geographic access, request parameters, methods, and sizes. It fits teams that want centrally managed Layer 7 traffic protection within the Azure ecosystem.
Pricing is structured across separate policy, rule, ruleset, and request-processing charges. The Policy plan starts at $5 per policy per month. Custom Rules add $1 per rule per month, while Custom Rules Requests Processed cost $0.60 per million requests. Default Ruleset adds $20 per month, and Managed Ruleset Requests Processed costs $1 per million requests. This structure gives smaller deployments a low starting point, but the total cost depends on the deployment and the volume of requests handled by custom and managed rules.
Its strongest fit is an Azure-centered environment that also uses Azure Front Door, Application Gateway, and Azure Monitor. The service combines managed rule sets with custom allow, block, log, redirect, and anomaly-score rules, plus bot protection and rate limiting. That breadth covers common web and API protection needs without requiring a separate WAF platform. Organizations seeking a broader integration range than Azure's verified connections may prefer a cloud alternative, while Azure users prioritizing native platform alignment and a $5 starting policy charge should consider this service.
