Fortigate HA Secondary device Fortiguard update

Hello,

I searched to find out how the Fortigate HA secondary device communicates with and updates the Fortiguard server, but couldn't find a clear answer.
A Fortigate HA cluster uses one VIP and its ARP is maintained by the master device.
So, is it correct that the auxiliary device receives update information through the heartbeat interface?
I would like to know the logic behind Fortigate HA Cluster updating Fortiguard information.

 

Thank you.

Your understanding is correct, only the Primary device connects with Fortiguard and updates the database. Secondary node syncs these db files with Primary node via the HA/Hearbeat link.
If for any reason the sync fails, you will see alerts as below.

secondary's external files are not in sync with the primary's,sequence:1. (type IDS)
secondary's external files are not in sync with the primary's,sequence:3. (type CERT_CA)
