Drupal is an open source content management system (CMS) that is widely used to create and manage websites and web applications. It allows users without significant technical knowledge to create and edit content, customize the design, and extend the functionality of websites using modules and themes. Drupal is noted for its flexibility, which makes it suitable for creating various types of websites - from simple blogs and corporate portals to complex social networks and e-commerce.

One of the main advantages of Drupal is its modular structure. The core platform contains the basic functionality, and additional features are implemented through modules that can be installed as needed. This allows developers and site administrators to add new features without having to change the core code. There are many free and paid modules that extend the functionality of Drupal, including tools for SEO, social media integration, media management, analytics, and more.

Drupal is also famous for its security and scalability. It is used to create websites of various sizes and complexity, including government portals, corporate websites, and news resources. The high security of the platform is confirmed by numerous successful implementations in areas where security is crucial. In addition, Drupal supports multilingualism and has built-in tools for creating multilingual sites, making it an ideal choice for international projects.
