Manage TDR Groups
In Threat Detection and Response, you can create groups of the hosts on your network. With these groups, you can:
- Specify a group name in a policy to configure different policies for different hosts.
For more information, see Configure TDR Policies. - See and manage Host Sensors, group membership, and Host Sensor settings for a group.
For more information, see Manage Hosts In a Group.
TDR supports three types of groups:
Active Directory Group
Active Directory groups are created in TDR when AD Helper sends the device group information from your Active Directory server to TDR. You manage membership in these groups on your Active Directory domain controller. You can synchronize the Active Directory group on your Active Directory server with TDR from the Groups page in the TDR web UI.
Host Group
You can add a Host group, which is a list of hosts. A host can be a member of only one Host group. An Operator can manage Host Sensors for members of the group and configure Host Sensor settings specific to the group. You can create and add members to a Host Group from the Groups page or from the Hosts page.
The easiest way to add multiple hosts to a group is from the Hosts page. For more information, see Manage TDR Hosts and Host Sensors.
IP Subnet Group
You can add an IP Subnet group, which is for a specific IPv4 subnet. The group includes hosts with IP addresses in the IP subnet specified for the group.
The Groups page appears only for users with Analyst or Operator credentials. A user with Analyst credentials can see information about groups but cannot edit them.
From the Groups page, a user with Operator credentials can:
- Synchronize Active Directory groups
- Add, edit, and remove IP Subnet and Host groups
- Edit the members of a Host Group
- Install and remove Host Sensors for members of a Host group
- Configure Host Sensor settings for a Host group
See Threat Detection and Response Groups
To see the list of groups:
- Log in to the TDR web UI as a user with Operator or Analyst credentials.
- Select Configuration > Groups.
- To see information for a Host group, adjacent to the group name, click .
The hosts in the group and Host Sensor settings for the group appear.
A user with Operator credentials can add and edit IP Subnet and Host groups on this page. An Operator can also manage host sensor settings, and install and remove Host Sensors for members of a group.
Synchronize an Active Directory Group
From the Groups page, an Operator can synchronize the Active Directory groups. When you synchronize a group, AD Helper gets updated information about the group from the Active Directory domain controller and updates the group information in your TDR account.
To synchronize an Active Directory group:
- On the Groups page, adjacent to an Active Directory group, click .
- Select Sync Group.
A confirmation message about whether you want to synchronize the group appears. - Click Yes, Sync.
You must synchronize an Active Directory group before you can expand it on the groups page or change the Host Group membership for members of the Active Directory group.
Add a Group
From the Groups page, you can add a Host group or an IP Subnet group.
You can also use the Change Host Group action to add a Host Group for selected hosts. For more information, see Manage TDR Hosts and Host Sensors.
When you add a Host group, you specify the hosts in the group by name. Before you can add hosts to the group, you must know the names of the hosts. Because you can configure different Host Sensor settings for each group, a host cannot be a member of more than one Host group.
- On the Groups page, click Add Group.
The Add Group dialog box appears.
- In the Group Name text box, type a name for this group.
- From the Type drop-down list, select Host. This is the default option.

To manage Hosts in a group, adjacent to that group, click .
The group information appears on two tabs:
- Hosts — Shows the hosts in the group and includes network, OS, and the Host Sensor status for each host
- Host Sensor Configuration — Host Sensor settings for hosts in the group; you can configure Host Sensor settings for the group that take precedence over the global Host Sensor settings specified by the Administrator
On the Hosts tab, you can see information about the hosts in this group, and manage Hosts Sensors and group membership.
You can complete these actions for hosts:
- Change Host Group — Change the Host Group the host is a member of
- Install Sensor — Use AD Helper to install a Host Sensor on a Windows host
