What is the main function of Sophos Firewall's traffic shaping feature?

The main function of Sophos Firewall's traffic shaping feature is to manage bandwidth allocation and prioritize traffic for optimal network performance. This feature allows organizations to define rules that dictate how bandwidth is distributed among various types of traffic or applications. By prioritizing critical applications or users, traffic shaping ensures that essential services operate smoothly even during peak usage times. This capability is crucial in maintaining overall network efficiency and performance, as it reduces congestion and improves the user experience.

The other options relate to different aspects of network security and management. Enhancing physical security typically involves measures outside the scope of traffic shaping, such as securing hardware and controlling physical access to network devices. Providing a user interface for monitoring focuses on the visual tools available for managing the network rather than actively shaping traffic. Blocking unauthorized access is a fundamental aspect of firewall functionality but does not pertain to the specific task of managing bandwidth and traffic prioritization.
