What this solution brief helps you decide

Give the technical owner and the governance owner the same baseline to argue from.

Microsoft 365 posture evidence is spread across Entra, Intune, Defender, Purview, Secure Score and other administration areas. Rebuild that in a spreadsheet for a board pack or a customer review and the technical findings, the governance reporting and the remediation work quietly lose their shared baseline. The next assessment then starts again somewhere different.

This brief sets out how to keep one record. Published baselines and overlays are selected to fit the tenant and its obligations, with the excluded checks stated rather than assumed. Each finding carries supporting evidence, an accountable owner, a status and a proposed next step. An approved baseline is pinned so Secure Score movement and configuration drift can be reviewed against it.

It is careful with language, and says so. Secure Score is improvement guidance, not an absolute measure of breach risk and not proof of compliance, so the output supports a remediation and assurance discussion without claiming certification.

  • How to choose which published baselines and overlays apply, and record the ones deliberately excluded.
  • What makes a finding traceable: evidence, an owner, a status and a dated recheck.
  • Whether posture is measured once or monitored between reviews, and what each choice costs.
  • How to report Secure Score movement and configuration drift against a pinned state.
  • How to describe the result to leadership without overstating compliance or protection.

What you get

  • Two pages: where the decision gets difficult, what changes and how you measure it, and the four questions to settle first.
  • Three measures to track: checks in scope, open findings by owner, and movement from the pinned baseline.
  • A scope statement on what Secure Score does and does not establish.
  • One live decision to test the approach on, using a single baseline or one assurance question.

Who it is for

IT leaders, security and governance owners, compliance leads and MSPs preparing tenant assurance reviews. Written so a security engineer and a governance lead can work from the same two pages instead of two versions of the truth.
