Overview
Web applications are a primary attack surface for cybercriminals. SQL injection, cross-site scripting, bot attacks, and DDoS threats can compromise your data, disrupt services, and damage customer trust. Azure Web Application Firewall gives your organisation centralised, scalable protection without the overhead of managing physical appliances or additional software agents.
Azure WAF integrates natively with Azure Front Door and Azure Application Gateway, allowing you to enforce consistent security policies across all your web properties - from the network edge to your core datacenters.

Common Use Cases
Protecting Customer-Facing Web Applications
Retail, financial services, and healthcare organisations use Azure WAF to shield customer portals and transactional platforms from injection attacks, session hijacking, and automated credential stuffing.
Securing APIs and Microservices
Development teams integrating REST APIs or microservices architectures benefit from WAF's ability to inspect and filter API traffic, reducing exposure without slowing delivery pipelines.
Supporting DevSecOps Workflows
Azure WAF integrates with existing DevOps toolchains, enabling security policies to be defined as code and applied consistently across environments. This streamlines compliance and reduces the gap between development speed and security requirements.
Meeting Regulatory and Industry Standards
Organisations subject to PCI-DSS, HIPAA, ISO 27001, or other frameworks use Azure WAF as part of a broader compliance strategy, taking advantage of Azure's extensive certification portfolio and built-in policy enforcement tools.

Pricing
Azure Web Application Firewall operates on a pay-as-you-go model with no upfront costs or pre-commitments required. You pay only for what you use, making it accessible for organisations of all sizes - from growing mid-market businesses to large enterprises with complex multi-region deployments.
TechPower can help you forecast costs, identify the right WAF configuration for your workloads, and ensure you are not over-provisioning or paying for unused capacity.
