Microsoft has initiated the integration of native System Monitor (Sysmon) functionality into Windows 11. This development is significant for threat hunters and security operations centers (SOCs).
The feature has been introduced with the Windows 11 Insider Preview Build 26300.7733 (Dev Channel) as of Fri, Feb 3, 2026. Sysmon, a tool previously available as a standalone application, is now embedded in the operating system’s optional features.
Sysmon has been a crucial utility for cybersecurity experts, enabling the monitoring and logging of system activities in the Windows event log. Its native integration simplifies deployment within enterprise environments, facilitating the capture of detailed system events such as process creations and network connections without the need for third-party tools.
Key Technical Details
The integrated version of Sysmon mirrors the standalone version, supporting custom configuration files to filter events and minimize log noise. It is important to note that the feature is disabled by default. Administrators are required to enable it through Settings or PowerShell.
For systems with the standalone Sysinternals Sysmon agent installed, it must be uninstalled before activating the native Windows feature to prevent conflicts.
