What is the primary role of the FortiGate firewall?

The primary role of the FortiGate firewall is to protect network infrastructure from threats. This is achieved through a variety of security measures, including intrusion prevention, antivirus scanning, web filtering, and application control, all of which are integral components of a next-generation firewall. FortiGate firewalls are specifically designed to safeguard networks against attacks and unauthorized access, ensuring that sensitive data remains secure and that the network's integrity is maintained.

While providing internet access to users, monitoring network speed, and managing bandwidth allocation are important functions in network management, they are not the primary purpose of a FortiGate firewall. Instead, these functionalities can often be considered secondary roles that support the overall goal of maintaining a secure and efficient network environment. The focus of FortiGate is firmly rooted in threat protection and security management, making option B the most accurate representation of its primary role.
