What is osquery?

osquery is a powerful, open-source endpoint visibility tool developed by Facebook (now Meta). It allows administrators to monitor, manage, and secure their infrastructure by querying various aspects of their systems. osquery provides an SQL-based interface to explore operating system data, making it easier to detect and respond to security incidents.

With osquery, administrators can collect detailed information about their systems, including hardware and software inventory, configuration settings, running processes, and more. This information can be used to identify potential security threats, detect anomalies, and enforce compliance with organizational policies.
