Description This article describes disabling FortiGuard, including Antivirus (AV), Web Filtering, and Antispam.
Scope FortiGuard.
Solution

Disable FortiGuard Services Globally.

To disable FortiGuard, including Antivirus (AV), Web Filtering, and Antispam, use the following commands:

 

set outbreak-prevention-force-off enable 

 

set outbreak-prevention-force-off enable: This command disables the FortiGuard Virus Outbreak Prevention service.

 

set webfilter-force-off enable

 

set webfilter-force-off enable: This command forces Web Filtering to be turned off, bypassing any Web Filtering services provided by FortiGuard.

 

set antispam-force-off enable

 

set antispam-force-off enable: This command disables the FortiGuard Antispam service, preventing any antispam functionality provided by FortiGuard.

 

Verify the Configuration.

Run the following command to confirm that the settings are applied:

 

show full-configuration system fortiguard

 

This will display the current FortiGuard settings. Ensure that the values for avquery-force-off, webfilter-force-off, and antispam-force-off are set to enable.

 

Note:

  • Disabling FortiGuard services on a FortiGate device results in reduced security capabilities, as the device will no longer receive real-time updates for antivirus signatures, web filtering, and antispam, relying only on cached data.
  • This increases vulnerability to new threats, malicious websites, and spam, potentially exposing the network to security risks.
  • While core network functions and management features remain operational, the overall security posture is compromised, so disabling these services should be done with caution and a clear understanding of the potential risks involved.
