Create an investigation from a detection summary

You can add multiple detections to an investigation at the same time from a summary panel on the Detections page.

A summary panel appears when detections are grouped by Type in Summary view on the Detections page.

To add a group of detections to an investigation from a detection summary, complete the following steps:

  1. Log in to the ExtraHop system through https://<extrahop-hostname-or-IP-address>.
  2. At the top of the page, click Detections.
    By default, the page should be in Summary view with detections grouped by Type. If the page is not in Summary view, click Summary view and then group by Type.
  3. Click a detection type in your detections list.
  4. Click the criteria you want to filter by: participants, properties, network localities, or users.
  5. In the lower left corner of the summary panel, click the Bulk Actions drop-down menu, and select Add All Detections to an Investigation.
  6. Specify where you want to add the detections.
    • Click Add detections to a new investigation to create a new investigation.
    • Click Add detections to an existing investigation then select the investigation where you want to add the detections.
  7. Click Next.

Next steps

If you created a new investigation, type a name, and add notes. You can also set the status and assign the investigation to an ExtraHop user. If you added the detections to an existing investigation, review the name, status, assignee, and notes to make sure they reflect your changes.
