Using FortiSandbox Cloud with antivirus

Feature overview

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 compliances regarding data storage locations.

Support and limitations

• In FortiOS 6.2 and later, users do not require a FortiGate Cloud account to use FortiSandbox Cloud.
• Without a valid 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.
  • There is a limit on how many submissions are sent per minute.
  • The per-minute submission rate is based on the FortiGate model.
• FortiSandbox can be used with antivirus in both proxy-based and flow-based policy inspection modes.
• With FortiSandbox enabled, full scan mode antivirus can do the following:
  • Submit only suspicious files to FortiSandbox for inspection.
  • Submit every file to FortiSandbox for inspection.
  • Do not submit anything.
• Quick scan mode antivirus cannot submit suspicious files to FortiSandbox. It can only do the following:
  • Submit every file to FortiSandbox for inspection.
  • Do not submit anything.

Network topology example

Configuring the feature

To configure antivirus to work with an external block list, the following steps are required:

1. Through FortiCare, register the FortiGate device and purchase a FortiGuard antivirus license
2. Enable FortiSandbox Cloud on the FortiGate
3. Enable FortiSandbox inspection
4. Enable the use of the FortiSandbox database

To obtain or renew an AVDB license:

1. Please see the video How to Purchase or Renew FortiGuard Services for FortiGuard antivirus license purchase instructions.
2. Once a FortiGuard license has been purchased or activated, users will be provided with a paid FortiSandbox Cloud license.
   1. Go to Global > Dashboard > Status to view the FortiSandbox Cloud license indicator.

      

   2. Users can also view this indicator at Global > System > FortiGuard.

      

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 Global > Security Fabric > Settings and enable Sandbox Inspection.

   

4. Select FortiSandbox Cloud and choose a region from the dropdown list.

   

5. Click Apply to save the settings.

   

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

   

To enable FortiSandbox inspection:

1. Go to Security Profiles > AntiVirus.
2. Enable FortiSandbox inspection by selecting either Suspicious Files Only or All Supported Files.

   

3. Files can be excluded from being sent to FortiSandbox based on their file types by choosing from a list of supported file types.

   

4. Files can also be excluded from being sent to FortiSandbox by using wildcard patterns.

   

5. Click Apply.

To enable the use of the FortiSandbox database:

1. Go to Security Profiles > AntiVirus.
2. Enable Use FortiSandbox Database.

   

3. Click Apply.

Diagnostics and debugging

• Checking FortiGate Cloud controller status:
