surface, network protection in Windows prevents people from accessing dangerous IP addresses and domains that may host phishing scams, exploits, and other malicious content.

New DNS and TLS protocol versions strengthen the end-to-end protections needed for applications, web services, and Zero Trust networking. File access adds an untrusted network scenario with Server Message Block over QUIC, and new encryption and signing capabilities. Wi-Fi and Bluetooth advancements also provide greater trust in connections to other devices. In addition, VPN and Windows Firewall platforms offer new ways to easily configure and debug software.
