| Encryption and data protection | Wherever confidential data is stored, it must be protected against unauthorized access, whether through physical device theft or from malicious applications. Windows provides strong at-rest data-protection solutions that guard against nefarious attackers. <br/><br/> Learn more about [Encryption](encryption-data-protection.md). | Encryption and data protection | Wherever confidential data is stored, it must be protected against unauthorized access, whether through physical device theft or from malicious applications.

| Encrypted Hard Drive | <br/><br/>Encrypted Hard Drive uses the rapid encryption that is provided by BitLocker Drive Encryption to enhance data security and management. <br> By offloading the cryptographic operations to hardware, Encrypted Hard Drives increase BitLocker performance and reduce CPU usage and power consumption. Because Encrypted Hard Drives encrypt data quickly, enterprise devices can expand BitLocker deployment with minimal impact on productivity. <br/><br/> Learn more about [Encrypted Hard Drives](information-protection/encrypted-hard-drive.md). <br><br/> | | Encrypted Hard Drive | <br/><br/>Encrypted Hard Drive uses the rapid encryption that is provided by BitLocker Drive Encryption to enhance data security and management. <br> By offloading the cryptographic operations to hardware, Encrypted Hard Drives increase BitLocker performance and reduce CPU usage and power consumption.

| Windows Defender Firewall | Windows Defender Firewall is a stateful host firewall that helps secure the device by allowing you to create rules that determine which network traffic is permitted to enter the device from the network and which network traffic the device is allowed to send to the network. Windows Defender Firewall also supports Internet Protocol security (IPsec), which you can use to require authentication from any device that is attempting to communicate with your device. <br><br/> Learn more about [Windows Defender Firewall with advanced security](threat-protection/windows-firewall/windows-firewall-with-advanced-security.md).<br/><br/> | Windows Defender Firewall | Windows Defender Firewall is a stateful host firewall that helps secure the device by allowing you to create rules that determine which network traffic is permitted to enter the device from the network and which network traffic the device is allowed to send to the network.

| Antivirus & antimalware protection | Microsoft Defender Antivirus is included in all versions of Windows 10, Windows Server 2016 and later, and Windows 11. 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/>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/>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).| | Antivirus & antimalware protection | Microsoft Defender Antivirus is included in all versions of Windows 10, Windows Server 2016 and later, and Windows 11.
