What is Azure Rights Management

Question

Does Azure Rights Management (ARM) have something to do with security? How exactly is it useful?

Answer 1

Azure Rights Management (often abbreviated to Azure RMS) is the protection technology used by Azure Information Protection.

This cloud-based protection service uses encryption, identity, and authorization policies to help secure your files and email, and it works across multiple devices—phones, tablets, and PCs. 

Information can be protected both within your organization and outside your organization because that protection remains with the data, even when it leaves your organization’s boundaries.
