The risk

Microsoft secures the platform. The rest is up to you.

Microsoft 365 is essential for modern businesses, but many organisations don't realise that Microsoft's protection only goes so far. Under the shared responsibility model, Microsoft secures the platform, while you are responsible for user identities, access controls and configuration settings.

Even a single misconfiguration can expose your business to unnecessary risk: an admin account without MFA, legacy authentication left switched on, or files shared publicly by default.

Our audit identifies these gaps and gives you straightforward, actionable guidance to strengthen your defences, protect sensitive data and improve compliance.

What we review

  • Identity, MFA and conditional access
  • Admin roles and privileged access
  • Email security and forwarding rules
  • SharePoint, OneDrive and Teams sharing
  • Defender and Secure Score settings
  • Audit logging and alerting
