Vanessa received a PDF file that appeared empty. Which component of SandBlast protection is her company using on a Gateway?

The correct answer is that the company is likely using SandBlast Threat Extraction. SandBlast Threat Extraction is designed to remove potentially malicious content from a document, such as a PDF. When a file is processed by this component, it sanitizes the document by eliminating any suspicious or dangerous elements while preserving the intended content. This often results in files that might appear empty, especially if the malicious parts were integral to the visible content.

In the context of the question, Vanessa receiving an empty PDF suggests that the threats embedded within the file were successfully extracted, leaving the document void of any harmful components. The goal of this approach is to ensure that users only receive safe versions of files, without exposing them to potential malware.

Other components like SandBlast Threat Emulation and SandBlast Agent serve different purposes. Threat Emulation is focused on analyzing files in a virtual environment to detect threats before they reach the user, while the SandBlast Agent is an endpoint solution that protects individual devices from various types of attacks but does not specifically handle the sanitization of documents in the way Threat Extraction does. Check Point Protect is a more general concept related to overall protection and doesn't specifically address the handling of documents like the other options do.
