PCI DSS requires the use of regularly updated antivirus protection. The antivirus functionality of the FortiGate unit protects both the FortiGate unit and the networks it manages. Workstations on these networks can be protected using FortiClient Endpoint Security. Both FortiGate and FortiClient antivirus protection can receive updates from Fortinet’s FortiGuard service. Workstations can also use third-party antivirus applications with update services.

The FortiGate unit can enforce the use of antivirus software, denying unprotected workstations access to the network.
