What is the function of the FortiGate device?

The FortiGate device is primarily designed to serve as a next-generation firewall (NGFW). This means it not only controls traffic through a set of predefined security rules but also integrates additional functions that enhance its security capabilities, such as intrusion prevention systems (IPS), application control, antivirus protection, and web filtering.

As a next-generation firewall, FortiGate devices are equipped to operate at multiple layers of the network stack, allowing them to inspect data packets in great detail and to understand the context of applications being used. This enables them to prevent breaches and attacks by blocking malicious activity while allowing legitimate traffic through. The device's comprehensive security posture is essential in today’s complex network environments, where traditional firewalls may not suffice due to the sophistication of modern cyber threats.

Choosing this option reflects an understanding of how FortiGate fits within the broader security architecture of an organization, emphasizing the device's primary role in maintaining cybersecurity through advanced traffic management and protection features.
