 Windows 11 raises the bar for network security, offering comprehensive protection to help people work with confidence from almost anywhere. To help reduce an organization's attack
 surface, network protection in Windows prevents people from accessing dangerous IP addresses and domains that may host phishing scams, exploits, and other malicious content.
 Using reputation-based services, network protection blocks access to potentially harmful, low-reputation domains and IP addresses.

 Windows 11 requires all PCs to use Unified Extensible Firmware Interface (UEFI)'s Secure Boot feature. When a Windows 11 device starts, Secure Boot and Trusted Boot work together to prevent malware and corrupted components from loading. Secure Boot provides initial protection, then Trusted Boot picks up the process.
