Executive SummaryUpdated on Apr 20, 2025
Imperva Web Application Firewall and Microsoft Azure Application Gateway compete in the web application security market. Imperva seems to have the upper hand in providing robust security features, while Azure Application Gateway stands out for its ease of integration and scalability within Azure's cloud platform.
Features: Imperva Web Application Firewall provides strong security features such as correlated attack validation, threat radar, profiling policies, and DDoS protection. These tools ensure comprehensive security with effective customization. Microsoft Azure Application Gateway focuses on ease of use, comprehensive cloud integration, and traffic management features. It allows organizations to manage their traffic efficiently while offering scalability through Azure's cloud services.
Room for Improvement: Imperva needs enhancements in GUI, policy management, and cloud component integration to improve user experience. Users find policy management complex and request better traffic visibility. Azure Application Gateway could improve its interface, flexibility in configuring rules, and provide more detailed documentation for configuration and updates. Performance during updates and limitations on request size and protocol support also need improvement.
Ease of Deployment and Customer Service: Imperva Web Application Firewall supports on-premises, private, public, and hybrid cloud deployments but needs improved support response times and localization. Microsoft Azure Application Gateway is primarily cloud-based, integrating seamlessly with Azure services, contributing to ease of deployment although the initial setup may appear complex. Enhanced support could benefit users.
Pricing and ROI: Imperva's pricing is considered high but offers strong ROI, particularly in banking. Its licensing model is complex. Microsoft Azure Application Gateway offers a pay-as-you-go model which adjusts based on usage, although some users find it expensive. Both provide meaningful ROI, but their pricing approaches differ significantly.
