Installing SentinelOne Agents on Devices

  • Last updated on

Installing SentinelOne on your devices is the final step in deploying SentinelOne protection in Barracuda RMM. Before you do this step, you must have already done the previous procedures:

To use SentinelOne, you must purchase your SentinelOne license from Barracuda Networks. Contact your Barracuda Networks sales representative.

When you install SentinelOne agents on devices, you choose a SentinelOne Manual group to move the device to in SentinelOne. Dynamic and Pinned groups are not available.

Applying a Default SentinelOne Monitoring Policy

If you want to apply a SentinelOne Antivirus monitoring policy to a group or device directly, see Applying a Monitoring Policy to a Group or Device.

Installing SentinelOne Agents on Devices

macOS devices can be protected by SentinelOne. No extra steps are required.

You can perform the SentinelOne agent install on any number of devices at the same time. The install will occur in batches of 10. For example, if you selected 20 devices during the procedure, the first 10 will install, then the next 10.

If you select multiple devices and one has the agent already deployed, that device is skipped, and the rest deploy.

You can select any number of devices for install at the same time, as long as those devices are in the same Barracuda RMM site. When you install on a large number of devices, the agent is deployed in groups of 10. For example, if you choose 100 devices, the process will install on the first 10 first, then proceed to the next 10.

It can take up to 2 minutes for the install to begin on devices. Once the install has begun, it can take up to 3 minutes for the install to complete. The more devices you choose to install on at the same time, the longer the install will take to fully complete.

The following are the Deployment Statuses you may see on in the device table:

This deployment status...indicates...
-The SentinelOne agent has not been installed on the device, or has been deleted.
Install FailedAn install was attempted on the device, but was not successful.
Install PendingAn install is in progress on the device.
InstalledThe SentinelOne agent has been successfully installed on the device.
  • If the device has the Deployment Status of Failed Install, the agent must be uninstalled and the device rebooted before a new agent can be installed on it. This can occur if a SentinelOne agent has previously been installed on a device or if an install was interrupted and could not be completed.
  • Deleting the SentinelOne group before the agent install is complete causes the install to fail. If this happens, you may have to uninstall the agent, reboot the device, then install an agent from another SentinelOne group.
  To install SentinelOne agents on devices
SentinelOne agent install only supports the Basic proxy authentication type. If the device is using a different proxy authentication type, the install fails.
  1. In Service Center, click Configuration > Integrations > SentinelOne.
  2. Click the expand button expand.jpg next to the site where you want to deploy SentinelOne to devices.
  3. Click the checkboxes of devices you want to deploy to.
  4. Click Install.
  5. Select the SentinelOne group you want to add the device to.
    You can only add devices to Manual groups. Dynamic and Pinned groups are not available.
  6. Click Install.
    During the install, Deployment Status of devices is Install Pending.

 

If the device’s Deployment Status changes to Installed, but also has a yellow warning icon SentinelOneWarning.png, it means the agent is installed, but requires a reboot. Follow the To reboot devices procedure below.

If the device’s Deployment Status changes to Failed Install, the device may have had a previous SentinelOne agent that failed to uninstall, or requires a reboot before a new agent can be installed successfully. See To uninstall SentinelOne agents or To reboot devices below.

A SentinelOne monitoring policy must be in place on the site you want to protect. You may want to review Using the Default SentinelOne Monitoring Policies.

To uninstall SentinelOne agents
Due to third-party limitations, after you uninstall an agent, the Deployment Status of the device displays as Failed Install. You can change this status by rebooting the device.
  1. In Service Center, click Configuration > Integrations > SentinelOne.
  2. Click the expand button expand.jpg next to the site where you want to remove the SentinelOne agent from devices.
  3. Click the checkboxes of devices you want to uninstall the agent from.
  4. Click Uninstall.
  5. In rare cases, a Reboot Device error may pop up during the uninstall, if this happens, click Cancel. Clicking Reboot will shut down the device and changes the device’s Deployment Status to Reboot Pending, but will not reboot the device. The device will only be shut down. You will not be able to unlink the site until the device that is in the status of Reboot Pending has been turned on and the uninstall allowed to complete.
    If you want to install a SentinelOne agent again, you must reboot before the install can be started. See To reboot devices below.
To reboot devices

Devices require a reboot when they have the Deployment Status of Failed Install. This can occur when an install is interrupted, or when an agent has been uninstalled from the device but the device hasn’t been rebooted yet.

  1. In Service Center, click Configuration > Integrations > SentinelOne.
  2. Click the expand button expand.jpg next to the site where you want to reboot devices.
  3. Click the checkboxes of devices you want to deploy to.
  4. Click Reboot.
To update SentinelOne Agents on devices

If you want to update a SentinelOne agent on a device, you must uninstall the existing agent, reboot the device, then install a new agent. See the following procedures, above:

  • To reboot devices
