In TAP threat and campaign views, the columns typically reflect a funnel of exposure and interaction. “Intended” (B) represents the number of targeted recipients—i.e., how many users the attacker attempted to reach (often including messages that were blocked or not ultimately delivered). “At Risk” usually reflects users who actually received the message (delivered) and were therefore exposed, while “Impacted” reflects users who interacted with the threat (clicks, credential entry, or other measurable engagement depending on the threat type and telemetry). “Highlighted” is a classification/flagging mechanism (not a population count of targets). For IR detection and analysis, “Intended” is crucial for estimating the campaign’s scope and potential blast radius at the earliest stage—before you know how many were delivered or clicked. Analysts use Intended to decide whether to escalate, whether to run broad retroactive searches, and whether to apply preventative blocks (domains/URLs) quickly. Then they pivot to At Risk and Impacted to prioritize immediate containment actions for exposed and interacting users.
