 | Antivirus & antimalware protection | Microsoft Defender Antivirus is included in all versions of Windows 10, Windows Server 2016 and later, and Windows 11. <br/><br/>From the moment you boot Windows, Microsoft Defender Antivirus continually monitors for malware, viruses, and security threats. Updates are downloaded automatically to help protect your device from threats.  Microsoft Defender Antivirus continually scans for malware and threats, and also detects and blocks potentially unwanted applications (applications that can negatively impact your device even though they are not considered malware).<br/><br/>If you have another antivirus app installed and turned on, Microsoft Defender Antivirus will turn off automatically. If you uninstall the other app, Microsoft Defender Antivirus will turn back on. <br/><br/>Microsoft Defender Antivirus integrates with cloud-delivered protection, which helps ensure near-instant detection and blocking of new and emerging threats.<br/><br/>Learn more about [next-generation protection and Microsoft Defender Antivirus](/microsoft-365/security/defender-endpoint/microsoft-defender-antivirus-windows).| 
 | Attack surface reduction rules | Your attack surfaces are the places and ways you are vulnerable to a cyber attack. Attack surface reduction rules are built into Windows and Windows Server. These rules block certain behaviors that are often abused to compromise your device or network. Such behaviors can include launching scripts or executables that attempt to download or run other files, running suspicious scripts, or performing other behaviors that apps don't typically initiate during normal work. You can configure rules to protect against risky behaviors.<br/><br/> Learn more about [Attack surface reduction rules](/microsoft-365/security/defender-endpoint/attack-surface-reduction) |
 | Anti-tampering protection | Attacks like ransomware attempt to disable security features, such as anti-virus protection, on targeted devices. Bad actors like to disable security features to get easier access to user’s data, to install malware, or to otherwise exploit user’s data, identity, and devices without fear of being blocked. Tamper protection helps prevent these kinds of activities.<br/><br/>With tamper protection, malware is prevented from taking actions such as:<br/>- Disabling virus and threat protection<br/>- Disabling real-time protection<br/>- Turning off behavior monitoring<br/>- Disabling antivirus (such as IOfficeAntivirus (IOAV))<br/>- Disabling cloud-delivered protection<br/>- Removing security intelligence updates <br/><br/>Learn more about [Tamper protection](/microsoft-365/security/defender-endpoint/prevent-changes-to-security-settings-with-tamper-protection). |

+| Network protection | Network protection in Windows helps prevent users from accessing dangerous IP addresses and domains that may host phishing scams, exploits, and other malicious content on the Internet. Network protection is part of attack surface reduction and helps provide an additional layer of protection for a user. <br/><br/>Using reputation-based services, network protection blocks access to potentially harmful, low-reputation based domains and IP addresses. <br/><br/>In enterprise environments, network protection works best with [Microsoft Defender for Endpoint](/microsoft-365/security/defender-endpoint/?view=o365-worldwide), which provides detailed reporting into protection events as part of larger investigation scenarios.<br/><br/> Learn more about [Network protection](/microsoft-365/security/defender-endpoint/network-protection). |
