Web Download Protection

Define the settings for the SandBlast Agent Browser Extension to protect against malicious files that come from internet sources. The Browser Extension is supported on Google Chrome.

The automatic options are:

• Protect web downloads with Threat Extraction and Emulation - Send files for emulation. While a file is tested, users receive a copy of it with all suspicious parts removed. If the file is not malicious, users receive the original file when the emulation is finished. Emulation can take up to two minutes.
• Protect web downloads with Threat Emulation - Send files for emulation. Users do not receive a copy during the emulation. If the file is not malicious, users receive the original file when the emulation is finished. Emulation can take up to two minutes.
• Do not use web download protection - The SandBlast Agent Browser Extension is not active.

When Threat Extraction is selected, it only applies to file types that can be extracted, such as documents.

When Threat Emulation is selected, it only applies to file types that can be emulated, such as executables and scripts.

You can edit the selections manually to define more settings for Threat Extraction and Threat Emulation for different file types.

3. Select an option for emulation and access to the original file from the options shown. Different options show for different file types.
   • Extract and suspend original file until emulation completes - Send files for emulation. While a file is tested, the user receives a copy of it with all suspicious parts removed.
   • Emulate and suspend original file until emulation completes - Send files for emulation. Users only receive the files after the emulation finishes and the file was found to be safe.
   • Emulate original file without suspending access - Send files for emulation. Users can download and access the file while it is tested. The administrator is notified if files are found to be malicious.
   • Allow Download - No emulation or extraction. The download is allowed.
