What is the main difference between Inspection Mode and Flow Mode in FortiGate?

The main difference between Inspection Mode and Flow Mode in FortiGate is that Inspection Mode analyzes packets in detail for threats, while Flow Mode prioritizes faster routing with less intensive inspection.

In Inspection Mode, each packet is thoroughly scrutinized against various security policies and checks for threats, allowing for granular control and in-depth analysis of the data. This involves a more comprehensive examination of the content, which is essential for advanced threat detection and maintaining security integrity.

Conversely, Flow Mode is designed to optimize performance by speeding up the flow of traffic through the firewall. In this mode, the system performs minimal inspection, making it less resource-intensive and better suited for environments where performance is a higher priority than detailed security analysis. This mode allows packets to be routed more quickly since less time is spent analyzing each packet in depth.

While the other options touch upon various aspects of Inspection Mode and Flow Mode, they do not accurately highlight the key differences in terms of the trade-off between thorough threat analysis and routing performance, which is specifically captured in the correct answer.
