Exam FCP_FGT_AD-7.4 Topic 3 Question 16 Discussion

A: FortiGate uses fewer resources.
C: FortiGate adds less latency to traffic.
Flow-based inspection is a type of traffic inspection that is used by some firewall devices, including FortiGate, to analyze network traffic. It is designed to be more efficient and less resource-intensive than proxy-based inspection, and it offers several benefits over this approach.
Two benefits of flow-based inspection compared to proxy-based inspection are:
FortiGate uses fewer resources: Flow-based inspection uses fewer resources than proxy-based inspection, which can help to improve the performance of the firewall device and reduce the impact on overall system performance.
FortiGate adds less latency to traffic: Flow-based inspection adds less latency to traffic than proxy-based inspection, which can be important for real-time applications or other types of traffic that require low latency.
A: Fewer resources since it does not need to keep much in memory.
C: Samples traffic while it goes by, and only does makes allow or deny decision with the last package.
So client does not have to wait on FortiGate to scan the bulk of the packtets.
