Happy New Year.

Microsoft has renamed its Microsoft 365 A5 Security suite to the Microsoft Defender Suite. This change is purely a branding update—features and licensing remain the same.

What you need to know:

In the tenant, you will now see Microsoft Defender Suite instead of the previous A5 Security naming – see below example.

  • If you have changed from Microsoft M365 unified to Microsoft Defender Suite for Education you will need to assign these licenses.
  • If you were on Microsoft M365 Security, no action is required other than being aware of the new name when managing assignments.
If you have any questions about this change, please contact the schools licensing team on nzsc...@cyclone.co.nz

Regards
Paul
