DLP

Hi Michael_Obeng​ Microsoft 365 Business Premium does not include Endpoint Data Loss Prevention (Endpoint DLP) out of the box.

Couple of Options:

1.Upgrade to a plan that includes Endpoint DLP, like:

• Microsoft 365 E5, or
• Add-ons such as “E5 Compliance” or “E5 Information Protection & Governance” to your existing licenses.
  (You can trial “E5 Compliance” as a stand-alone add-on first)

2.Use alternatives:

• Defender for Cloud Apps (formerly MCAS) to block cloud uploads to services like Dropbox, Google Drive.
• Defender for Endpoint Device Control for blocking USB, Bluetooth, printing etc.
  These tools don't offer full DLP policy flexibility but can achieve targeted controls.
