Skip this if your organization treats email security as a checkbox behind a gateway tool; Abnormal assumes you're running a real SOC function and builds accordingly.

Skip this if your priority is post-breach recovery and forensics; GreatHorn is built for detection and user-facing remediation, not incident investigation depth.
