Network protection helps reduce the attack surface of your devices from Internet-based events. It prevents employees from using any application to access dangerous domains that may host phishing scams, exploits, and other malicious content on the Internet.

Network protection helps reduce the attack surface of your devices from Internet-based events. It prevents employees from using any application to access dangerous domains that may host phishing scams, exploits, and other malicious content on the Internet.
|

|

It expands the scope of [Windows Defender SmartScreen](../windows-defender-smartscreen/windows-defender-smartscreen-overview.md) to block all outbound HTTP(s) traffic that attempts to connect to low-reputation sources (based on the domain or hostname).
|
||||
|
||||
Network protection is supported beginning with Windows 10, version 1709.

Network protection works best with [Microsoft Defender Advanced Threat Protection](../microsoft-defender-atp/microsoft-defender-advanced-threat-protection.md), which gives you detailed reporting into Windows Defender EG events and blocks as part of the usual [alert investigation scenarios](../microsoft-defender-atp/investigate-alerts.md).
|
||||
|
||||
When network protection blocks a connection, a notification will be displayed from the Action Center. You can [customize the notification](customize-attack-surface-reduction.md#customize-the-notification) with your company details and contact information. You can also enable the rules individually to customize what techniques the feature monitors.
|
||||
|
||||
You can also use [audit mode](audit-windows-defender-exploit-guard.md) to evaluate how Network protection would impact your organization if it were enabled.
