Is an extra agent required for FortiGate observability?
FortiGate usually needs syslog/API flow; additional sources depend on deployment scope.
Observability
FortiGate security observability
Security observability turns raw FortiGate logs into operational views teams can act on.
Signals that matter
VPN sessions, admin logins, deny/allow actions, policy ID, user, country, ASN, and time windows should be observed together.
Why it differs from SIEM search
Search finds historical events; observability shows which risk pattern the system is approaching now.
