FortiClient at a glance
FortiClient is Fortinet's endpoint agent for VPN, endpoint protection and fabric integration, deployed on user devices. Fortinet ships regular FortiClient releases plus security advisories; as exposed VPN/endpoint software, timely updates matter.
For admins the priorities are keeping the agent current and its configuration secure. FortiClient connects to the corporate network (VPN) and integrates with the Fortinet fabric, so security fixes should be applied promptly — and its compatibility with the FortiGate/EMS side should be kept in step (check the matrix). Roll it out and update it through EMS or software distribution. Older versions on personal or rarely-used devices are the classic weak spot — enforce a minimum version.
