FortiGate Infrastructure 7.2 Study Guide (p.165): "ZTNA access proxy allows users to securely access resources through an SSL-encrypted access proxy. This simplifies remote access by eliminating the use of VPNs."

This is true because ZTNA access proxy is a feature that allows remote users to access internal applications without requiring VPN or user credentials. ZTNA access proxy uses a secure tunnel between the user’s device and the FortiGate, and authenticates the user based on device identity and context. The user only needs to install a lightweight agent on their device, and the FortiGate will automatically assign them to the appropriate application group based on their device profile. This simplifies remote access and enhances security by reducing the attack surface12

An antivirus profile in full scan mode buffers up to your specified file size limit. The default is 10 MB. That is large enough for most files, except video files. If your FortiGate model has more RAM, you may be able to increase this threshold. Without a limit, very large files could exhaust the scan memory. So, this threshold balances risk and performance. Is this tradeoff unique to FortiGate, or to a specific model? No. Regardless of vendor or model, you must make a choice. This is because of the difference between scans in theory, that have no limits, and scans on real-world devices, that have finite RAM. In order to detect 100% of malware regardless of file size, a firewall would need infinitely large RAM--something that no device has in the real world. Most viruses are very small. This table shows a typical tradeoff. You can see that with the default 10 MB threshold, only 0.01% of viruses pass through.

FortiGate Security 7.2 Study Guide (p.350 & 352): "In flow-based inspection mode, the IPS engine reads the payload of each packet, caches a local copy, and forwards the packet to the receiver at the same time. Because the file is ransmitted simultaneously, flow-based mode consumes more CPU cycles than proxy-based." "Each protocol’s proxy picks up a connection and buffers the entire file first (or waits until the oversize limit is reached) before scanning. The client must wait for the scanning to finish."
