I'm Merill Fernando, the creator of Maester. I grew up in Sri Lanka and know what it feels like when useful technology exists but is priced out of reach. Backing Maester Cloud helps keep the Maester core tests open, maintained, and free for admins, schools, nonprofits, and small teams everywhere.

Common questions
Data, security, residency, and how change detection works. See sponsor options →
What is Maester?
Maester is the open-source PowerShell security test framework for Microsoft 365, with hundreds of community-maintained checks across Entra, Intune, Exchange, Teams, and more. Maester Cloud is the service built around it: the hosted history, drift detection, and evidence layer for your Maester and Zero Trust Assessment results.
What am I paying for before launch?
Your pledge funds development now. Private preview opens August 2026, with GA targeted September 2026. You get founding status and roadmap input immediately, and the full service at GA.
When am I charged?
You are charged $99 today and then monthly, and you can cancel any time from the customer portal. As a Founding Supporter you lock in a lifetime 10% discount on any future Hosted Maester Cloud tier, plus a place on the Supporters wall if you opt in and a direct line to the roadmap.
What happens to my $99/month subscription at GA?
It simply continues as your self-hosted subscription: deployment in your own Azure subscription, updates, and support, plus your founding perks. If you would rather move to Hosted Maester Cloud, you can switch at any time; your lifetime 10% founding discount applies to any hosted tier, and you stop paying the $99 when you switch. Either way you can cancel whenever you like.
Does Maester Cloud run Maester for me?
Your choice. Keep running Maester and Zero Trust Assessment in your own environment and add one cmdlet to send the results, or let the hosted Maester Runner run everything inside Maester Cloud, no separate steps. Either way it stores, compares, alerts on, and preserves the results.
Where does my data live?
An isolated instance in the Azure region you choose. Send results from your own CI and Maester Cloud never connects to your tenant at all. Use the hosted Maester Runner and it reaches your tenant only through a single-tenant app you create and control (managed identity or federation, no secrets or certificates).
How does data residency work?
You choose an Azure region at setup. All report data (JSON, HTML, and history) is stored and processed in that region and stays there. Billing metadata may live in our central control plane, but security report data stays regional.
What data is actually stored?
Only Maester and Zero Trust Assessment results. When you send results yourself, Maester Cloud never connects to your tenant. You run the tests and export the output. If you use the hosted Maester Runner, it reaches your tenant only through a single-tenant app you create and control (managed identity or federation, no secrets or certificates).
Is AI on by default?
No. Maester Cloud ships with AI disabled. Maester AI is an opt-in add-on you turn on only if you want it, and it arrives after GA (after September 2026). Separately, the Maester MCP is free for everyone: a Model Context Protocol server you can plug into any agent, including Microsoft Foundry, Microsoft Copilot, and Microsoft Security Copilot, so your own copilots can query Maester tests and results.
How are changes detected?
Each export is diffed against your previous run for the same tenant, surfacing new failures, fixes, and accepted risks, pinned to a date and run ID across 5+ years of tenant history.
How do alerts reach me?
Through your own Microsoft 365 shared mailbox, connected at setup. Notifications come from your tenant with a familiar sender identity, not from us.
How much tenant history is kept?
Hosted Cloud is private-preview only during the funding launch. We expect hosted plans to retain tenant history for 5+ years, with one retained run per tenant per day. Custom retention can be discussed during onboarding.
How does Maester Cloud authenticate users?
Portal access is Entra-only after setup. You control access by assigning users to your own Entra app role. V1 treats users as a single access level; granular roles can come later.
How does the subscription support open source?
Every paid plan helps keep the Maester tests open, maintained, and aligned with CIS, CISA, and evolving standards. You receive a real service while funding better security for the whole community.
