The correct answer is true. NGFWs offer application-level control, which includes the ability to enforce granular policies within applications. This means that while an application as a whole might be permissible, specific behaviors or features – like file transfers within a messaging application – can be selectively blocked, while other functionalities, such as chatting, are allowed to continue. This level of control is beyond traditional port- and protocol-based firewalls and is a distinguishing feature of NGFWs.
