What is the purpose of application control in FortiGate?

The purpose of application control in FortiGate is to identify and manage application usage within a network. This feature enables organizations to gain visibility into the applications being used, allowing them to monitor traffic and enforce policies according to organizational needs. By doing so, network administrators can prioritize certain applications, limit bandwidth consumption for non-essential applications, and apply specific security measures for potentially harmful applications. This granular control is essential for maintaining a secure and efficient network environment.

In contrast, other options do not align with the function of application control. Improving device performance is typically associated with optimization techniques rather than application management. Blocking all internet traffic would not be practical for most organizations, as it would prevent users from accessing necessary resources. Enforcing strong user authentication relates more to identity and access management rather than application control, which focuses on monitoring and regulating application traffic specifically.
