NGINX Application Platform A suite of products that together form the core of what organizations need to create applications with performance, reliability, security, and scale. 7 The NGINX Application Platform is a suite of products that together form the core of what organizations need to create applications with performance, reliability, security, and scale. The NGINX Application Platform includes NGINX Plus for load balancing and application delivery, the NGINX WAF for security, and NGINX Unit to run the application code, all monitored and managed by NGINX Controller.
