FAQ
Common Questions
Does this tool connect to our Microsoft 365 tenant?
No. This is a self-reported questionnaire — it does not connect to your tenant or read your actual product deployment. Results reflect the answers you provide.
How is this different from the Microsoft 365 Security Readiness Assessment?
The Readiness Assessment covers the tenant-wide security baseline (identity, email, device, data settings). This planner maps to the full five-layer product architecture — including Defender for Endpoint and Purview specifically — for organizations planning their broader product stack, not just baseline settings.
