Maester

Maester enables administrators to define, execute, and validate security checks across Microsoft 365 tenants. It facilitates continuous monitoring of tenant configurations, ensuring settings align with security best practices and identifying deviations that could compromise the environment's integrity.

Maester is designed for security engineers, Microsoft 365 administrators, and compliance officers responsible for maintaining tenant security posture. It is ideal for professionals tasked with managing complex identity environments and ensuring consistent adherence to organizational security policies.

Maester is an open-source project available under the MIT license, allowing for free use, modification, and distribution. There are no licensing fees for the framework itself, though users are responsible for any costs associated with the underlying cloud infrastructure used to execute the checks.
