What is the main function of FortiGate regarding TCP traffic?

The main function of FortiGate regarding TCP traffic is to process and inspect TCP traffic between endpoints and protected servers. FortiGate appliances are designed to act as next-generation firewalls, which means they provide deep packet inspection capabilities. This involves analyzing the contents of TCP packets to identify malicious payloads, inspect for compliance with security policies, and allow or block traffic based on a variety of parameters such as application type, user identity, and session state.

By inspecting TCP traffic, FortiGate can effectively manage quality of service (QoS), respond to threats in real-time, and maintain secure communications between devices and servers. This enables organizations to maintain a secure network that adheres to their security policies while also ensuring that legitimate traffic can flow freely without unnecessary disruption.

Other options, while relevant aspects of network security management, do not capture the core focus of FortiGate's role in handling TCP traffic. Monitoring bandwidth usage is important for performance management but does not encompass the comprehensive traffic inspection capabilities provided by FortiGate. Similarly, providing firewall protection for sensitive data and preventing unauthorized access to server logs are crucial functions of a security infrastructure but are secondary to the primary role of processing and inspecting traffic to ensure security across the network.
