Network protection helps protect devices from certain Internet-based events by preventing connections to malicious or suspicious sites. Network protection is an attack surface reduction capability that helps prevent people in your organization from accessing domains that are considered dangerous through applications. Examples of dangerous domains are domains that host phishing scams, exploits, and other malicious content on the Internet. Network protection expands the scope of [Microsoft Defender SmartScreen](/windows/security/threat-protection/microsoft-defender-smartscreen/microsoft-defender-smartscreen-overview) to block all outbound HTTP(S) traffic that attempts to connect to low-reputation sources (based on the domain or hostname).

Network protection extends the protection in [Web protection](web-protection-overview.md) to the operating system level, and is a core component for Web Content Filtering (WCF). It provides the web protection functionality found in Microsoft Edge to other supported browsers and non-browser applications. Network protection also provides visibility and blocking of indicators of compromise (IOCs) when used with [Endpoint detection and response](overview-endpoint-detection-response.md). For example, network protection works with your [custom indicators](manage-indicators.md) that you can use to block specific domains or host names.
