# Host List and the Query Builder
The **Host List** is located at the bottom of the [Rogue Report](/technical-documentation/admin-guides/epiphany-intelligence-platform-administrator-guide/epiphany-tools/rogue-report.md). It shows each user that meets the criteria set up using the filters at the top of the pane. In the image below, this report shows *all* users, regardless of which tools they are using. You can tell this by the colored rectangles at the top, which show Windows AD, CrowdStrike, and Tenable.
Host List
You can quickly filter the information by removing and adding data sources from the list:
* Select the “x” next to a data source name to remove it from the list.
* To add a data source you previously removed, expand the drop-down list and select it.
Expand the drop-down list (on the right) and select a data source.
* To change the detail shown in the list, select the **Advanced Filter**/**Basic Filter** switch on the left.
* To perform an advanced query to potentially identify devices that aren’t using the required tools, select the filter icon . This is described in the next section.
### Query Builder
Based on our example images, let’s assume you need to build a query to show you the users in Windows Active Directory who aren’t using CrowdStrike.
1. Select the filter icon .
2. Select **in +** and then select **windows\_ad+** .
3. Select **not +** and then select **crowdstrike+** .
4. Select **Run Query**.
This builds a query that tells Epiphany to list all users who are using Windows AD but not using Crowdstrike. These are the devices you need to ensure start using Crowdstrike. You can download this list as a .csv file and it can become a worklist.
