Using FortiSandbox Cloud with antivirus

FortiSandbox Cloud allows users to take advantage of FortiSandbox features without having to purchase, operate, and maintain a physical appliance. It works the same way as the physical FortiSandbox appliance.

FortiSandbox Cloud allows you to control the region where your traffic is sent to for analysis. This allows you to meet your country's compliance needs regarding data storage locations.

FortiSandbox can be used with antivirus in both proxy-based and flow-based inspection modes. When FortiSandbox is enabled, full scan mode antivirus can submit the following for inspection: only suspicious files, all supported file, or no files. Quick scan mode antivirus cannot submit suspicious files to FortiSandbox, so either all files or no files are submitted for inspection.

In FortiOS 6.2 and later, users do not require a FortiGate Cloud account to use FortiSandbox Cloud. Without a valid FortiGuard antivirus (AVDB) license, FortiGate devices are limited to 100 FortiGate Cloud submissions per day. Unlimited FortiGate Cloud submissions are allowed if the FortiGate has a valid AVDB license; however, there is a per-minute submission rate is based on the FortiGate model.

For more information, see FortiSandbox.

Configuring FortiSandbox Cloud

There are three steps to configure FortiSandbox Cloud inspection in an antivirus profile:

1. Through FortiCare, register the FortiGate device and purchase a FortiGuard antivirus license.
2. Enable FortiSandbox Cloud on the FortiGate.
3. Enable FortiSandbox inspection options in the antivirus profile.

To obtain or renew a FortiGuard antivirus license:

1. See the How to Purchase or Renew FortiGuard Services video for FortiGuard antivirus license purchase instructions.
2. Once a FortiGuard license is purchased and activated, users are provided with a paid FortiSandbox Cloud license.
   1. Go to Dashboard > Status to view the FortiSandbox Cloud license indicator.

      

   2. Alternatively, go to System > FortiGuard to view the FortiSandbox Cloud license indicator.

      

To enable FortiSandbox Cloud on the FortiGate:

1. Make the FortiSandbox Cloud feature visible:

   config system global
       set gui-fortisandbox-cloud enable
   end

2. Log out of FortiOS and log in again.
3. Go to Security Fabric > Fabric Connectors and double-click the FortiSandbox card.
4. For status, click Enable.
5. For Type, click FortiSandbox Cloud and choose a region from the dropdown list.
6. Click OK.

   When the FortiGate is connected to the FortiSandbox Cloud, the current FortiSandbox database version is displayed.

To enable FortiSandbox inspection options in the antivirus profile:

1. Go to Security Profiles > AntiVirus.
2. Edit an antivirus profile, or create a new one.
3. Under APT Protection Options, select either Suspicious Files Only or All Supported Files.
4. For Do not submit files matching types, click the + to exclude certain file types from being sent to FortiSandbox.
5. For Do not submit files matching file name patterns, click the + to enter a wildcard pattern to exclude files from being sent to FortiSandbox.

   

6. Enable Use FortiSandbox Database.
7. Click OK.
