Guest User Management

Control external access with governed onboarding, automated lifecycle, and scheduled access reviews across your M365 tenant.

External collaboration is essential, but uncontrolled guest access creates security blind spots. Affirmatic Guest User Management gives you the answers and the controls.

The hidden risk of unmanaged guest access

Native M365 guest management lacks the visibility and automation security teams need at enterprise scale.

Visibility gaps

Most teams cannot see which guests are active or what they access.

Lifecycle neglect

Guests stay long after projects end, expanding your attack surface.

Audit anxiety

Manual reviews cannot keep up with compliance expectations.

How to manage guest users in Microsoft 365

  1. Use controlled onboarding instead of ad-hoc invites.
  2. Assign accountable sponsors for every guest.
  3. Set time-limited access with automatic expiry.
  4. Require periodic access reviews.
  5. Monitor guest activity and access scope.
  6. Maintain documented audit trails for every decision.

Scheduled reviews confirm continued need and create a clear audit trail of decisions.

Powered by the Affirmatic Governance Framework

Four governance pillars keep every module aligned. Expand each pillar to see what it delivers.

Ownership

Ensure every workspace, guest, and resource has clear ownership, escalation paths, and audit-ready accountability.

  • Designated owners are assigned at creation.
  • Ownership gaps trigger escalation workflows.
  • Ownership changes are fully audited.

Lifecycle

Automate expiry, renewal, archiving, and cleanup to prevent sprawl and maintain security over time.

  • Expiry policies align with business needs.
  • Owners receive renewal prompts before expiry.
  • Actions are configurable: archive, lock, or delete.

Request approval

Route creation and access changes through governed workflows with the right approvers and audit trails.

  • Approval chains align with risk and sensitivity.
  • Requests create full audit records.
  • Self-service is enabled with guardrails.

Templates

Standardize provisioning with templates for naming, metadata, sensitivity labels, and policy enforcement.

  • Naming and metadata standards are enforced at creation.
  • Templates apply policies consistently across object types.
  • Templates are versioned and governed.
