Investigative information is the extra context security tools attach to a detection so analysts can understand why something was flagged. It may include sender details, message headers, URLs, file hashes, related alerts, user actions, and links to other events in the same campaign. The goal is not just to say “this is suspicious,” but to explain what made it suspicious.
This matters because defenders rarely investigate one alert in isolation. Context helps separate a false positive from a real threat, trace how an attacker moved through a system, and decide whether multiple messages or endpoints are connected. In practice, investigative information appears in phishing detections, malware alerts, and collaboration-platform warnings such as suspicious chat messages or QR-code links. Good investigative data speeds triage, supports incident response, and improves hunting by revealing patterns across otherwise ordinary-looking activity.
