Your environment improved this month, but three material exposures remain. Identity is stable. Data protection needs attention. AI adoption introduced two new governance gaps.

What changed since your last visit

Material exposures

Risk that spans domains. Not a list of failed checks — a prioritized executive backlog.

SIA executive brief

What should I care about today?

Three developments deserve your attention. External data exposure increased after a SharePoint configuration change. Two privileged identities remain outside your target access model. Copilot usage increased while AI data controls remain incomplete.

MFA fatigue protection is not fully configured

Authentication methods policy does not enforce number matching and additional context for Microsoft Authenticator across all user groups. 412 of 1,840 accounts remain on plain approve/deny push.

CISMicrosoft Zero TrustNIS2 / CBWDefend 365 Baseline

Impact: Push-based approval without number matching enables MFA bombing against privileged accounts.
Affected: 412 accounts · 3 groups

Recommended remediation

  1. 1.Enable number matching and additional context in the Authentication methods policy.
  2. 2.Scope the policy to All users, exclude only break-glass accounts.
  3. 3.Monitor sign-in logs for 7 days for legacy client failures.
