## How threats are remediated ## How threats are remediated
Depending on how you set up the device groups and their level of automation, each automated investigation either requires user approval (default) or automatically takes action to remediate threats. Depending on how you set your organization's level of automation, each automated investigation either requires user approval (default) or automatically takes action to remediate threats. The following table describes each level of automation and how it works.
> [!NOTE]
> Microsoft Defender for Endpoint tenants created on or after August 16, 2020 have **Full - remediate threats automatically** selected by default. You can keep the default setting, or change it according to your organizational needs. To change your settings, [adjust your device group settings](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-atp/configure-automated-investigations-remediation#set-up-device-groups).
You can configure the following levels of automation:
|Automation level | Description| |Automation level | Description|
|---|---| |:---|:---|
|**Full - remediate threats automatically** | All remediation actions are performed automatically. Remediation actions that were taken can be viewed in the [Action Center](auto-investigation-action-center.md), on the **History** tab.<br/><br/>***This option is recommended** and is selected by default for tenants that were created on or after August 16, 2020 with Microsoft Defender for Endpoint, with no device groups defined yet.* <br/><br/>*If you do have a device group defined, you will also have a device group called **Ungrouped devices (default)**, which will be set to **Full - remediate threats automatically**.* | |**Full - remediate threats automatically** <br/>(also referred to as *full automation*)| With full automation, all remediation actions are performed automatically, and can be viewed in the [Action Center](auto-investigation-action-center.md), on the **History** tab.

|**No automated response** | Automated investigation does not run on your organization's devices.

> If your tenant already has device groups defined, then the automation level settings are not changed for those device groups. > - New tenants (which include tenants that were created on or after August 16, 2020) with Microsoft Defender for Endpoint are set to full automation by default.
> - Full automation has proven to be reliable, efficient, and safe, and is recommended for all customers. Data collected and analyzed over the past year shows that customers who are using full automation had 40% more high-confidence malware samples removed than customers using lower levels of automation. Full automation frees up your critical security resources so they can focus more on your strategic initiatives.
> - If your security team has defined device groups that include certain levels of automation, those settings are not changed by new default settings that are rolled out. However, we recommend using full automation wherever possible.
> - You can keep your default automation setting, or change it according to your organizational needs. To change your settings, [set your level of automation](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-atp/configure-automated-investigations-remediation#set-up-device-groups).
