Executive SummaryUpdated on Jan 1, 2025

NGINX App Protect and Azure Web Application Firewall are competitors in the web application security space. Azure appears to have the upper hand due to its ease of integration within its ecosystem and cost-effective pricing options.

Features: NGINX App Protect is known for its flexibility, reverse proxy capabilities, and open-source nature. It is effective in managing HTTP sessions and traffic inspection while offering command-line interface support. Azure Web Application Firewall is highlighted for its easy configuration, seamless Azure ecosystem integration, and effective request filtering with custom rules.

Room for Improvement: NGINX App Protect could improve its flexibility in configuration and face challenges with integration and throughput. It also needs better dashboard views and simpler policy management. Azure Web Application Firewall could enhance its documentation and provide clearer deployment tutorials. It would benefit from more affordable pricing plans for medium to small enterprises.

Ease of Deployment and Customer Service: NGINX App Protect supports both on-premises and cloud environments but has inconsistent technical support. Azure Web Application Firewall is easier to deploy within Azure with generally good support, though improvements are needed for non-Microsoft environments.

Pricing and ROI: NGINX App Protect offers varied pricing based on needs and is considered expensive, though beneficial for network security. Azure Web Application Firewall offers flexible, enterprise-friendly pricing, making it attractive for larger deployments, though attention to cost management is essential.

Featured Reviews

Mano Senaratne

Head of Digital Engineering, Management Consultant at Stax Inc.

Comprehensive suite simplifies configuration while frequent updates require management

Mainly, it comes with the complete suite of Microsoft services. I can use it in conjunction with the best options and other features that come with it. Configuration is much easier than using different platforms. For example, if I have hosted the application in AWS and am using the Application Firewall from Azure, there are certain additional steps to follow when configuring them. With Microsoft, everything is within a single suite, making it easier to configure and plan. Azure continually upgrades platforms and sends us messages to upgrade to the next version, simplifying the process. Later, it's much easier if I want to upgrade the software platform, scale it, or move it to a different application host as the whole suite comes together. The return on investment is good. If I am doing applications for clients, I can invoice them for better costs. Most applications that I run and use have a better return on investment.

Long-term web protection has supported reliable traffic management but needs a simpler interface

NGINX App Protect is a good product. I have used both versions from F5 -also the free version- (I mean the NGINX/NGINX One/App Protect free trial period), and I think it is a good product. It's stable, affordable, and easy to manage. NGINX App Protect is a comprehensive security solution that combines advanced WAF, DoS protection, API security, and DevSecOps automation in a lightweight, scalable package ideal for modern cloud-native architectures. The adaptive machine learning capabilities are truly commendable, as the solution can establish traffic baselines and detect anomalies in real time. It automatically adjusts security policies, minimizing the need for manual intervention and reducing false positives. Additionally, it supports scalable deployment across diverse environments, including on-premises, cloud, Kubernetes, and containers, offering both flexibility and scalability I have experience with the web server, F5 load balancer, and similar products provided by Ergon, for eg. the web application firewall and the Microgateway for K8S. I'm also familiar with F5 BIG-IP products.
