What is osquery?

osquery is an open-source, scalable endpoint visibility tool that provides a universal endpoint agent to collect and analyze data from various operating systems, including Windows, macOS, and Linux. It allows administrators to define SQL tables to collect and analyze various types of data, such as process information, network connections, and file system data. osquery is widely used in the industry for its ability to provide a unified and efficient way to collect and analyze endpoint data, making it an essential tool for safety and security.

Main Features of osquery

Some of the key features of osquery include:

• Endpoint visibility: osquery provides a comprehensive view of endpoint data, allowing administrators to monitor and analyze various aspects of endpoint activity.
• SQL-based queries: osquery uses SQL to define tables and collect data, making it easy to query and analyze endpoint data.
• Scalability: osquery is designed to handle large-scale deployments and can collect data from thousands of endpoints.
