# Past Investigations

Past investigations are closed cases listed under the **Completed** tab. They preserve who was involved, threat context, and collaboration history without cluttering active work queues.

## Overview

After you [close an investigation](/closing-an-investigation), it no longer appears under **In Progress** or **Pending** for operational triage. Completed cards retain investigation IDs, subject names, threat badges, and summaries so you can verify outcomes and support audits. For how open cases are structured, see [Investigations](/investigations).

## The Completed Tab

The tab bar still shows counts for **In Progress** and **Pending** (for example “In Progress (0)”, “Pending (3)”) so you can see backlog at a glance while browsing history. Selecting **Completed** lists resolved investigations only.

Cards may show **multiple avatars** when several people collaborated on the same case. Subject names and threat types match the conventions used on open investigations.

## Reviewing Past Cases

Use completed cards to confirm how similar threats were handled, which [enforcement actions](/enforcement-status) were taken, and who participated. Search or filter behavior depends on your deployment; the list itself is ordered for recent closure by default in typical configurations.

## Investigation History

History is the sequence of status changes, assignments, and outcomes tied to each investigation ID. Together with notes from [closing](/closing-an-investigation), it forms the audit trail for Enforce. Cross-reference IDs when correlating with Predict or external ticketing systems.
