NSE4 Security Profiles Practice Question
An administrator wants to integrate FortiSandbox with a FortiGate to analyze suspicious files. Which security profile must be configured to send files to FortiSandbox?
⚠ Common exam trap
It's easy for candidates to assume FortiSandbox can be integrated with multiple security profiles (like IPS or Web Filter) for file analysis, but only the Antivirus profile supports the file-forwarding mechanism to FortiSandbox.

Correct answer & explanation
✓
Antivirus profile with FortiSandbox enabled
FortiSandbox integration with FortiGate requires the Antivirus profile to be configured with FortiSandbox enabled. This is because FortiSandbox is designed to analyze suspicious files that are typically detected by the antivirus engine, and the Antivirus profile is the only security profile that can forward files to FortiSandbox for advanced threat detection. The Antivirus profile uses the 'fortisandbox' option under 'scan-mode' to send files that cannot be conclusively determined as clean or malicious.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Application Control profile with FortiSandbox enabled
Why it's wrong here
Application Control profiles identify and track which applications are running on the network using signature-based detection, but they do not inspect file contents or submit files to FortiSandbox for behavioral analysis. FortiSandbox integration requires a profile that handles file transfers and malware payloads, which Application Control does not manage. Therefore, enabling FortiSandbox in an Application Control profile has no effect on sandboxing actual files.
- ✓
Antivirus profile with FortiSandbox enabled
Why this is correct
An Antivirus profile is the correct integration point because FortiGate's antivirus inspection can forward suspicious files to FortiSandbox for dynamic, sandbox-based analysis. During traffic inspection, the AV engine can detect unknown or low-confidence threats and send the associated file to FortiSandbox to identify zero-day malware. This provides an additional layer of protection beyond standard signature-based antivirus scanning.
- ✗
IPS profile with FortiSandbox enabled
Why it's wrong here
IPS profiles focus on detecting and preventing exploits using attack signatures and protocol anomaly detection, not on examining file payloads in detail. While FortiSandbox can consume logs or threat intelligence from IPS, the actual file submission for sandboxing is configured only in the Antivirus profile. Thus, enabling FortiSandbox in an IPS profile does not enable file sandboxing and is therefore incorrect for this integration.
- ✗
Web Filter profile with FortiSandbox enabled
Why it's wrong here
Web Filter profiles control access to URLs and categorize websites based on FortiGuard database lookups, operating at the request/response layer without inspecting downloadable file contents. FortiSandbox integration specifically requires a profile that inspects file streams and can quarantine or submit files for analysis, which Web Filter does not perform. Hence, enabling FortiSandbox in a Web Filter profile would not send any files to the sandbox.
