MICROSOFT 365 AUDIT

Microsoft 365 Business Premium security review

Review Business Premium security configuration, assignments and evidence before deciding whether additional licences are needed.

Discuss your requirements

Start with capabilities and assignments

A useful Business Premium review begins with the actual licence inventory and the workloads in use. Ask whether available identity, email and device capabilities are assigned, configured and operated for the intended users. Mixed licence estates and add-ons need explicit confirmation.

A practical sequence

  • Confirm licence assignments and active populations
  • Review identity and administrator protection, including exceptions
  • Reconcile device enrolment, compliance and access requirements
  • Examine effective email policy coverage and sharing controls
  • Validate available logging and operational ownership
  • Separate configuration actions from optional entitlement changes

Do not silently assume every enterprise feature

Business Premium includes Conditional Access through Entra ID P1. Risk-based policies based on user and sign-in risk require P2. Other advanced capabilities have their own entitlement requirements; an audit should identify the dependency rather than prescribe an unavailable setting.

Prepare your audit request
