Block Malicious Website has nothing to do with infected files. Since Realtime Protection is OFF, it will be allowed without being scanned.

Based on the settings shown in the exhibit:

Realtime Protection:OFF

Dynamic Threat Detection:OFF

Block malicious websites:ON

Threats Detected:75

The "Realtime Protection" setting is crucial for preventing infected files from being downloaded and executed. Since "Realtime Protection" is OFF, FortiClient will not actively scan files being downloaded. The setting "Block malicious websites" is intended to prevent access to known malicious websites but does not scan files for infections.

Therefore, when a user tries to download an infected file, FortiClient will allow the file to download without scanning it due to the Realtime Protection being OFF.

For adding user authentication to the ZTNA access for remote or off-fabric users, the following FortiGate feature is required in addition to ZTNA:

FortiGate explicit proxyallows FortiGate to intercept web traffic for authentication purposes.

ZTNA integrates with various FortiGate features to provide secure access and ensure that users are authenticated before accessing resources.

By using an explicit proxy, FortiGate can handle web traffic and enforce authentication policies for remote users who are not directly on the corporate network (off-fabric).

Thus, the correct feature to use for this requirement is the FortiGate explicit proxy.
