 | 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). 
 | BitLocker | BitLocker Drive Encryption is a data protection feature that integrates with the operating system and addresses the threats of data theft or exposure from lost, stolen, or inappropriately decommissioned computers. BitLocker provides the most protection when used with a Trusted Platform Module (TPM) version 1.2 or later. <br/> <br/> Learn more about [BitLocker](information-protection/bitlocker/bitlocker-overview.md). |
 | 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/> |
-| Virtual Private Network | Virtual private networks (VPNs) are point-to-point connections across a private or public network, such as the Internet. A VPN client uses special TCP/IP or UDP-based protocols, called tunneling protocols, to make a virtual call to a virtual port on a VPN server. <br><br/>Learn more about [Virtual Private Networks](identity-protection/vpn/vpn-guide.md) (VPNs).<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. 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/>
 | 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).| 
 | 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) |
