Oversharing in Microsoft 365: Where does it go wrong?
???? “I didn’t know all these files were shared (yet)…”
A phrase we unfortunately hear often in companies working with Microsoft 365.
Without realizing it, sensitive documents may be floating around in Teams, SharePoint or OneDrive.¹
Oversharing occurs not because of unwillingness, but because of lack of structure and understanding:
-
???? Too many permissions for remote guests
-
❓ Unclear who has access to which documents
-
???? No central governance policies or control mechanisms
And that carries risks:
-
Loss of confidential information
-
Data breaches that result in fines or reputational damage
-
Unnecessary chaos in file management
➡️ Without clear agreements and smart tooling, companies simply cannot securely collaborate in Microsoft 365.
At ALTA-ICT B.V., we help organizations to:
-
???? Gain insight into their data streams
-
???? Apply smart governance without blocking productivity
-
✅ Ensure compliance toward standards such as ISO 27001, NEN 7510 and NIS2
