NGINX Plus also has NGINX App Protect. It's a separate module, which is inspired by the F5 apps.
NGINX Plus offers advanced web traffic control, scalability, and stability with zero downtime during server transitions. It features a simple configuration, excellent connection efficiency, and supports authentication, caching, and load balancing. Known for handling DoS attacks and superior geographical routing, NGINX also benefits from community support. However, it requires improvements in scalability, module management, memory zone integration, and integration with Grafana. Enhancements in automation and pricing are also needed for better maintenance and value.
