 Hardware and firmware-level attacks have continued to rise in recent years, as modern security solutions made persistence and detection evasion on the operating system more difficult. Attackers compromise the boot flow to achieve low-level malware behavior that's hard to detect, posing a significant risk to an organization's security posture.

 The UEFI scanner is a new component of the [built-in antivirus](microsoft-defender-antivirus-windows.md) solution on Windows 10 and newer versions, and gives Defender for Endpoint the unique ability to scan inside of the firmware filesystem and perform security assessment. It integrates insights from our partner chipset manufacturers and further expands the comprehensive endpoint protection provided by Defender for Endpoint.

 With its UEFI scanner, [Defender for Endpoint](https://www.microsoft.com/microsoft-365/windows/microsoft-defender-atp) gets even richer visibility into threats at the firmware level, where attackers have been increasingly focusing their efforts on. Security operations teams can use this new level of visibility, along with the rich set of detection and response capabilities in Defender for Endpoint, to investigate and contain such advanced attacks.

+
+The following phishing email thresholds are available only in anti-phishing policies in Defender for Office 365. These thresholds control the sensitivity for applying machine learning models to messages for phishing verdicts:
 
 - **1 - Standard**: This is the default value. The severity of the action that's taken on the message depends on the degree of confidence that the message is phishing (low, medium, high, or very high confidence). For example, messages that are identified as phishing with a very high degree of confidence have the most severe actions applied, while messages that are identified as phishing with a low degree of confidence have less severe actions applied.
 - **2 - Aggressive**: Messages that are identified as phishing with a high degree of confidence are treated as if they were identified with a very high degree of confidence.
 - **3 - More aggressive**: Messages that are identified as phishing with a medium or high degree of confidence are treated as if they were identified with a very high degree of confidence.
 - **4 - Most aggressive**: Messages that are identified as phishing with a low, medium, or high degree of confidence are treated as if they were identified with a very high degree of confidence.
 
-The chance of false positives (good messages marked as bad) increases as you increase this setting. For information about the recommended settings, see [anti-phishing policy settings in Microsoft Defender for Office 365](recommended-settings-for-eop-and-office365.md#anti-phishing-policy-settings-in-microsoft-defender-for-office-365).

 Verify these policies are working. Safe Links and Safe Attachments protection is turned on by default, thanks to Built-in protection in [preset security policies](preset-security-policies.md). Anti-phishing has a default policy that applies to all recipients where anti-spoofing protection is turned on by default. Impersonation protection isn't turned on in the policy, and therefore needs to be configured.
