Windows 11 introduces several new security features designed to enhance protection from the chip to the cloud. Key features include secured-core PCs, which are 60% more resilient to malware, and the Microsoft Pluton Security Processor that isolates sensitive data. Additionally, Windows 11 supports multifactor authentication and passwordless sign-ins through passkeys, which help reduce the risk of password-related attacks. Organizations have reported a 58% reduction in security incidents since enabling these features.

Windows 11 aims to eliminate the need for passwords by introducing passwordless authentication options like passkeys. Passkeys create unique cryptographic credentials that are securely stored on devices, allowing users to sign in using biometric methods such as face recognition or fingerprints. This approach significantly reduces the risk of phishing attacks, with over 4,000 password attacks occurring every second, according to Microsoft.

Windows 11 includes several tools to support IT teams, such as Config Refresh, which reverts policies to a secured state if tampered with, and Custom App Control, which allows only approved applications to run on devices. Additionally, Windows Hello for Business enables phish-resistant credentials, removing the need for passwords entirely. These features help IT maintain security and streamline policy management effectively.
