Architecture & deployment
저널링 (Journaling)
Definition
Sending a copy of every message to the security system for non-disruptive monitoring/audit.
For executives (CEO·CISO)
Zero impact on mail flow makes it near-risk-free — ideal as a PoC / audit entry point. Commonly missed: journaling only observes, it does not block — plan the move to inline blocking after value is proven, rather than stopping at monitoring.
