Events in FortiAnalyzer will be in one of four statuses. The current status will determine if more actions need to be taken by the security team or not.
The possible statuses are:
Unhandled: The security event risk is not mitigated or contained, so it is considered open.
Contained: The risk source is isolated.
Mitigated: The security risk is mitigated by being blocked or dropped.
(Blank): Other scenarios.

However, no matter the moment, Fortigate will upload logs encrypted or unencrypted based on previous / differente config).
