Windows Enhances Security with Post-Quantum Features

At IGNITE 2025, Microsoft revealed new Windows security advancements, including Post-Quantum Cryptography APIs and enhanced encryption measures. These updates aim to prepare organizations for emerging quantum threats.

Key Security Enhancements

• Post-Quantum Cryptography (PQC) APIs introduced to bolster future security against quantum threats.
• BitLocker upgraded with hardware-accelerated disk encryption and silicon-level key protection for new devices from Spring 2026.
• Passkey manager integration in Windows Hello enables compatibility with various password managers.
• Sysmon integrated into Windows 11 and Server 2025 for advanced threat logging.
• Zero Trust DNS strengthens network security by enforcing encrypted server interactions.

App and Driver Resilience

Windows 11 enhances application security with App Control for Business and Intune's Managed Installer, ensuring only trusted apps and drivers operate. Antivirus has been moved to user mode, reducing kernel crashes. Improved driver resilience results from higher certification standards and driver isolation techniques.

Future-Proof Networking

Enterprise users benefit from Wi-Fi 7 support, featuring mandatory WPA3-Enterprise authentication. This advancement aligns with the broader aim to reinforce network security and adaptability to developing technologies.
