Modern endpoint security encompasses protection from the device firmware to the cloud, covering all phases of the device lifecycle. Each Microsoft Surface device is designed with advanced hardware and firmware that enhances security. Microsoft maintains the Unified Extensible Firmware Interface (UEFI) and provides tools like Windows Update for Business and Microsoft System Center Configuration Manager (SCCM) to ensure timely software updates.

Microsoft offers several advanced authentication methods to enhance security. Windows Hello provides biometric authentication, eliminating the need for passwords by recognizing faces or fingerprints. Additionally, Microsoft 365 Conditional Access allows access to resources based on specific criteria, while the Microsoft Authenticator app supports multifactor authentication for secure online access.

Microsoft offers various tools to help IT manage device security throughout its lifecycle. Windows Autopilot enables zero-touch deployment, simplifying the setup process. Microsoft Endpoint Manager allows management down to the firmware level via the cloud, and Microsoft Intune provides the capability to wipe and reset devices, ensuring they remain secure whether lost, stolen, or reassigned.
