Governance Compliance Score 0% Complete

Check each governance control to evaluate tenant health.

1 Identity, Access & Guest Boundaries

Conditional Access Enforced: Require compliant or hybrid Entra ID joined devices for accessing sensitive corporate SharePoint sites.

External Sharing Restrictions: Disable anonymous "Anyone with link" tenant-wide; require B2B one-time passcode verification for external guests.

Entra ID Access Reviews: Automated 90-day access reviews for external users with automatic revocation upon non-response.

2 Teams & SharePoint Sprawl Mitigation

Group Creation Controlled: Standardize group and team provisioning through an approval workflow with required secondary owner.

Group Expiration Policy: 180-day activity-based group expiration with automated renewal notifications sent to team owners.

Version History Limits: Enable intelligent SharePoint version trimming (e.g., 50 versions max) to save terabytes of billable storage.

3 Data Protection & Power Platform DLP

Purview Sensitivity Labels: Standardized 3-tier label taxonomy applied to all containers and Office document libraries.

Power Platform DLP Rules: Strict connector isolation preventing data movement between enterprise M365 and consumer storage APIs.

M365 Tenant Governance Audit & Implementation Matrix

Enterprise Microsoft 365 governance requires a structured operational cadence across security, identity, data lifecycle, and application sprawl. Below is our senior architect roadmap for quarterly compliance.

Identity & Access Management

Enforce Entra ID Conditional Access policies with risk-based MFA, compliant device filters, and session controls. Conduct automated monthly reviews of Global Administrator, Privileged Role Administrator, and SharePoint Administrator role assignments using Privileged Identity Management (PIM).

External Sharing & Guest Lifecycles

Disable anonymous "Anyone with the link" sharing across all sensitive site collections. Configure automated 90-day guest user access reviews in Entra ID to revoke orphaned vendor access and purge stale external sharing permissions.

Purview Data Classification & Retention

Deploy mandatory sensitivity labels across Exchange, SharePoint, and Teams. Enforce automated classification rules for PCI-DSS, PII, and financial records with strict DLP rules blocking exfiltration via personal cloud sync or public AI tools.

Power Platform & Copilot Governance

Implement the Microsoft Power Platform Center of Excellence (CoE) Starter Kit. Enforce tenant DLP policies restricting custom connectors and isolate Default environment citizen workflows from production enterprise databases.

Quarterly Microsoft 365 Governance Execution Roadmap

Month 1: Identity & PIM

Review Entra ID role assignments, revoke stale Global Admin privileges, and configure emergency "break-glass" accounts with continuous monitoring.

Month 2: Data & Retention

Audit Purview sensitivity label coverage, check auto-labeling simulation results, and review SEC 17a-4 WORM compliance locks.

Month 3: Power Platform & Teams

Run CoE Starter Kit telemetry, clean up orphaned Power Apps, review guest user access expiration, and archive inactive Teams channels.
