One of the key features of Firewalld is its ease of use, with a simple command-line interface (CLI) and a graphical user interface (GUI) available for those who prefer visual management. It also allows for configuration changes on the fly, enabling teams to apply security measures without service interruptions. Firewalld is widely adopted due to its robust set of features, including support for rich features like IP sets, filters, and more.
