How to: Custom configurations
Because meeting all the use cases only using the settings is not an option (even with [external plugins](https://docs.bunkerweb.io/1.6.7/plugins/?utm_campaign=self&utm_source=github)), you can use custom configurations to solve your specific challenges.

Under the hood, BunkerWeb uses the notorious NGINX web server, that's why you can leverage its configuration system for your specific needs. Custom NGINX configurations can be included in different [contexts](https://docs.nginx.com/nginx/admin-guide/basic-functionality/managing-configuration-files/#contexts) like HTTP or server (all servers and/or specific server block).

Another core component of BunkerWeb is the ModSecurity Web Application Firewall: you can also use custom configurations to fix some false positives or add custom rules, for example.
