What is NGINX?
NGINX is open-source web server software used for reverse proxy, load balancing, and caching. It provides HTTPS server capabilities and is mainly designed for maximum performance and stability. It also functions as a proxy server for email communications protocols, such as IMAP, POP3, and SMTP.

Benefits of NGINX
NGINX offers a highly scalable architecture that is very different from that of Apache (and many other open source and commercial products in the same category). It has a modular, event‑driven, asynchronous, single-threaded architecture that scales extremely well on generic server hardware and across multi-processor systems. NGINX uses all of the underlying power of modern operating systems like Linux to optimize the usage of memory, CPU, and network, and extract the maximum performance out of a physical or virtual server.

What is modsecurity?
ModSecurity is an open-source web-based firewall application (or WAF) that is designed to provide an additional layer of security for web applications and websites. It is supported by the following web servers: Apache, Nginx, LiteSpeed, and IIS.

Benefits of ModSecurity
ModSecurity addresses a wide range of threats and vulnerabilities that web applications and websites commonly face. It protects against attacks against web applications and allows for HTTP traffic monitoring, logging, and real-time analysis. ModSecurity interacts with Apache on the open-source web server. There are many advantages of using Mod_security and are resistant to various types of web attacks, including code injection, brute force, etc.
