Azure Rights Management (Azure RMS) is the cloud-based protection technology used by Azure Information Protection.
Azure RMS helps to protect files and emails across multiple devices, including phones, tablets, and PCs by using encryption, identity, and authorization policies.
For example, when employees email a document to a partner company, or save a document to their cloud drive, Azure RMS's persistent protection helps secure the data.
Protection settings remain with your data, even when it leaves your organization's boundaries, keeping your content protected both within and outside your organization.
Azure RMS may be legally required for compliance, legal discovery requirements, or best practices for information management.
Azure RMS ensures that authorized people and services, such as search and indexing, can continue to read and inspect the protected data.
Ensuring ongoing access for authorized people and services, also known as "reasoning over data", is a crucial element in maintaining control of your organization's data. This capability may not be easily accomplished with other information protection solutions that use peer-to-peer encryption.
Protection features
Feature
Description
Protect multiple file types
In early implementations of Rights Management, only Office files could be protected, using built-in Rights Management protection.
Azure Information Protection provides support for additional file types. For more information, see Supported file types.
Protect files anywhere
When a file is protected, the protection stays with the file, even if it is saved or copied to storage that is not under the control of IT, such as a cloud storage service.
Collaboration features
Feature
Description
Safely share information
Protected files are safe to share with others, such as an attachment to an email or a link to a SharePoint site.
If the sensitive information is within an email message, protect the email, or use the Do Not Forward option from Outlook.
Support for business-to-business collaboration
Because Azure Rights Management is a cloud service, there’s no need to explicitly configure trusts with other organizations before you can share protected content with them.
Collaboration with other organizations that already have a Microsoft 365 or a Microsoft Entra directory is automatically supported.
For organizations without Microsoft 365 or a Microsoft Entra directory, users can sign up for the free RMS for individuals subscription, or use a Microsoft account for supported applications.
Tip
Attaching protected files, rather than protecting an entire email message, enables you to keep the email text un-encrypted.
For example, you may want to include instructions for first-time use if the email is being sent outside your organization. If you attach a protected file, the basic instructions can be read by anyone, but only authorized users will be able to open the document, even if the email or document is forwarded to other people.
Platform support features
Azure RMS supports a broad range of platforms and applications, including:
Feature
Description
Commonly used devices not just Windows computers
Client devices include:
- Windows computers and phones - Mac computers - iOS tablets and phones - Android tablets and phones
- Exchange Server - SharePoint Server - Windows Server running File Classification Infrastructure
Application extensibility
Azure Rights Management has tight integration with Microsoft Office applications and services, and extends support for other applications by using the Azure Information Protection client.
The Microsoft Information Protection SDK provide your internal developers and software vendors with APIs to write custom applications that support Azure Information Protection.
Organizations always have the choice to stop using the Azure Rights Management service without losing access to content that was previously protected by Azure Rights Management.
Customized protection templates provide a quick and easy solution for administrators to apply policies, and for users to apply the correct level of protection for each document and restrict access to people inside your organization.
For example, for a company-wide strategy paper to be shared with all employees, apply a read-only policy to all internal employees. For a more sensitive document, such as a financial report, restrict access to executives only.
For new subscriptions, activation is automatic. For existing subscriptions, activating the Rights Management service requires just a couple of clicks in your management portal, or two PowerShell commands.
Auditing and monitoring services
Audit and monitor usage of your protected files, even after these files leave your organization’s boundaries.
For example, if a Contoso, Ltd employee works on a joint project with three people from Fabrikam, Inc, they might send their Fabrikam partners a document that's protected and restricted to read-only.
Azure RMS auditing can provide the following information:
Whether the Fabrikam partners opened the document, and when.
Whether other people, who were not specified, attempted, and failed to open the document. This might happen if the email was forwarded on, or saved to a shared location.
Because Azure Rights Management runs as a cloud service with the Azure elasticity to scale up and out, you don’t have to provision or deploy additional on-premises servers.
Maintain IT control over data
Organizations can benefit from IT control features, such as:
Feature
Description
Tenant key management
Use tenant key management solutions, such as Bring Your Own Key (BYOK) or Double Key Encryption (DKE).
Use auditing and usage logging features to analyze for business insights, monitor for abuse, and perform forensic analysis for information leaks.
Access delegation
Delegate access with the super user feature, ensuring that IT can always access protected content, even if a document was protected by an employee who then leaves the organization. In comparison, peer-to-peer encryption solutions risk losing access to company data.
Enable single-sign on without replicating passwords to the cloud, by using AD FS.
Migration from AD RMS
If you've deployed Active Directory Rights Management Services (AD RMS), migrate to the Azure Rights Management service without losing access to data that was previously protected by AD RMS.
Security, compliance, and regulatory requirements
Azure Rights Management supports the following security, compliance, and regulatory requirements:
Support for nCipher nShield hardware security module (HSM) to store your tenant key in Microsoft Azure data centers.
Azure Rights Management uses separate security worlds for its data centers in North America, EMEA (Europe, Middle East and Africa), and Asia, so your keys can be used only in your region.
Certification for the following standards:
ISO/IEC 27001:2013 (./includes ISO/IEC 27018)
SOC 2 SSAE 16/ISAE 3402 attestations
HIPAA BAA
EU Model Clause
FedRAMP as part of Microsoft Entra ID in Office 365 certification, issued FedRAMP Agency Authority to Operate by HHS
PCI DSS Level 1
