Exhibit:

What is indicated by the icon shown in the ''Highlighted'' column?
In the TAP Dashboard, the ''Highlighted'' column is used to surface items that require analyst attention beyond basic volume metrics, including items that have been explicitly flagged for investigation outcomes. The icon shown corresponds to a false positive report (C), meaning the message or threat classification is being contested as benign but incorrectly condemned or prioritized as malicious. In Proofpoint workflows, this matters because false positives can disrupt business operations (legitimate suppliers, customer mail, internal systems) and can also hide real threats if analysts become desensitized to noisy alerting. Handling a highlighted false positive typically involves validating message authentication (SPF/DKIM/DMARC), reviewing TAP verdict drivers (URL/attachment detonation, reputation, MLX scoring where applicable), and confirming business legitimacy (known sender relationship, expected content, and user confirmation). When confirmed, analysts submit false positive feedback through the correct channel to improve future detection fidelity and reduce repeat quarantines. Operationally, false positive handling is part of detection hygiene: it improves signal quality, reduces alert fatigue, and ensures that high-confidence threats rise to the top of the triage queue.
