Maester Sponsor Maester
Maester is free and open source, for every team that needs to check its Microsoft 365 security. Sponsors keep it that way.
Keep Maester free
Sponsorship pays for Merill's time building and maintaining Maester, the test tenants every check is proven against, and the Microsoft licences those tenants need.
