Maester

Maester is an open-source framework designed to enhance the security of Microsoft 365 environments through automated testing and monitoring. Built on the Pester PowerShell testing framework, Maester introduces cloud capabilities and user-friendly reporting features. It includes over 40 pre-built tests sourced from the Entra ID Security Config Analyzer (EIDSCA), which are tailored to validate common security settings and configurations within Microsoft 365.

This tool is particularly valuable for organizations seeking to maintain robust security protocols in their Microsoft 365 setup. Maester facilitates continuous security monitoring, compliance validation, and change management by enabling users to write custom tests in PowerShell and integrate with GitHub Actions for automated, continuous monitoring. The framework also generates easy-to-understand reports, aiding in the assessment of the overall security posture.
