Our company (from Fortune 500 list) just finished the DLP migration project from previous solution to Microsoft Purview. More then 70000 client located in more than 70 countries is onboarded.

I can share that experience from the first person.

Beside that, I can talk about how that benefits DLP strategy and open possibilities for better integration with O365 environment, enabling MIP label based rules, cooperation with Inside Risk Management (IRM) and bringing controls and visibilities on Copilot for web usage.
