How to Disable Fortinet​? How to Turn Off Fortinet​

1. Disabling FortiCloud Login on a FortiGate Appliance

Use Case: Prevent administrators or the device itself from using FortiCloud single-sign-on, or to fully disable cloud-based control/update daemons.

A. CLI Method

The FortiGate CLI provides a single command to shut down all FortiCloud-related communication daemons:

config system global
    set cloud-communication disable
end

This command halts the forticldd and updated daemons, effectively stopping all FortiCloud and FortiGuard communications.

Steps:

1. SSH or console into your FortiGate.
2. Enter configuration mode: config system global.
3. Disable cloud communication: set cloud-communication disable.
4. Exit and save: end.

Implication: IPS, antivirus, and web-filter signature updates will no longer be downloaded automatically. If you require these, plan for manual updates or use a FortiManager as an internal update source.

B. GUI Method (FortiOS 7.x and later)

1. Log in locally to FortiGate’s web interface.
2. Navigate to System → FortiCloud.
3. Uncheck Enable FortiCloud Portal Login (or similar option).
4. Click Apply.

Note: GUI labels may vary by firmware version. Always consult your version’s Administration Guide for the exact menu path.

2. Disabling or Uninstalling FortiClient on Windows

Use Case: Remove endpoint protection or VPN client functionality from a Windows workstation.

A. Using Windows “Apps & Features” (Windows 10/11)

1. Open Settings → Apps → Apps & features.
2. Scroll to Fortinet Antivirus (or FortiClient).
3. Click it and select Uninstall, then follow the on-screen wizard.

B. “Force Uninstall” via the Fortinet Removal Utility

Some installations lock the uninstall option; in these cases:

1. Download the latest FortiClient Removal Utility from Fortinet support.
2. Run the utility as Administrator.
3. When prompted, choose Force Uninstall under Fortinet Antivirus.
4. Reboot the machine when complete.

Tip: Always confirm that no FortiClient processes are running in Task Manager before starting—otherwise the uninstall may silently fail.

3. Uninstalling or Disabling FortiGate Software Components on Windows

Use Case: In lab or testing environments, you may install FortiGate-related utilities that later need removal.

Typical Steps via Control Panel

1. Open Control Panel → Programs and Features.
2. Locate Fortinet FortiGate (or related utilities).
3. Right-click and select Uninstall/Change.
4. Follow the guided prompts, providing administrative credentials as needed.

Caution: Some older FortiGate utilities leave behind services. After uninstalling, open Services.msc and look for any forticldd, fctupd, or Forti... services—disable or delete them manually.

4. Advanced: Disabling FortiCloud Logging via Automation

For environments managed via automation (e.g., Ansible), you can disable FortiCloud logging with the fortios_log_fortiguard_setting module:

- name: Disable FortiCloud access to configuration & data
  fortinet.fortios.fortios_log_fortiguard_setting:
    vdom: "root"
    log_fortiguard_setting:
      status: "disable"
      access_config: "disable"
      conn_timeout: 5

This ensures that log transmission and cloud-based analytics are both turned off.

5. Best Practices & Considerations

• Backup Configuration
  Always back up your FortiGate config before disabling core services.
• Understand Security Trade-offs
  Disabling cloud updates means losing automatic threat intelligence feeds. If you still need updates but want to block internet access, consider using an internal FortiManager or proxy.
• Test in a Lab First
  Before rolling changes into production, replicate the disablement in a non-production environment to catch unexpected issues (e.g., broken policies, logging gaps).
• Document Changes
  Record CLI commands used, GUI paths, and dates of changes in your change-management system. This aids in troubleshooting and future audits.
