FortiManager communicates with managed devices by using several protocols. Device Manager, FortiGuard Manager, and FortiAnalyzer Features each use a different protocol to communicate with managed devices.
Device Manager contains all devices that are managed by the FortiManager unit. You can create new device groups, provision and add devices, and install policy packages and device settings. Device Manager communicates with devices by using the FortiGate-FortiManager (FGFM) protocol. See Firewall Devices.
FortiGuard Manager communicates with devices by using the FortiGuard protocol.
When FortiAnalyzer features are enabled for the FortiManager unit, the FortiView, NOC - SOC, Log View, Event Manager, and Reports panes are available. FortiAnalyzer features include tools for viewing and analyzing log messages, and the feature communicates with devices by using the logging protocol.
