Learn about IRM-encrypted documents and how they work

Updated over a week ago

What is IRM

IRM (Information Rights Management) – is the unique plugin-free protection mechanism that will apply an additional security level to your MS Office document to prevent its unauthorized access and distribution.

The feature will let users download IRM-encrypted documents and work with them in a protected native format on a local PC.

How it works

In case the document is assigned IRM permission, users will need to authenticate successfully with VDR credentials before opening the document. In addition, the document will be protected with watermarks. Saving changes (except for Excel), copying the content, and making screen captures will be disabled. At the same time, administrators can revoke access at any time, so the document cannot be opened again.


Supported formats

  • MS Word (*.doc, *.docx)

  • MS Excel (*.xls, *.xlsm, *.xlsx)

  • MS PowerPoint (*.ppt, *.pptx)


How to assign IRM permission

In the permission section, the administrator should apply "Download encrypted file" permission.

Two additional modes of access are available for MS Excel documents downloaded as encrypted files:

  • Secure analysis – users can see the formulas and analyze data by recalculating, applying their own formulas, editing the document, and saving the changes. Yet, creating a new copy of the document is disabled.

  • No formulas – users cannot see or edit formulas or the document itself.

ℹ️ Print option will be available if the document is assigned Upload, Download original, Download PDF, or Print permission. Learn more about available document permissions.


How to open IRM-encrypted files

  • Download the document in an encrypted format;

  • Open the IRM document downloaded to your computer;

  • Fill in your username (email) and password in the corresponding fields.

*In case 2-step verification is switched on, you will also have to fill in a one-time SMS code into the password field.

Please adhere to the following format: password#SMS code

The system will remember the successful authentication and won't ask users to re-authenticate within a timeout period. By default, the timeout is set to 8 hours, but it can be customized for your project by the Customer Support team.


System requirements

  • Windows 11, Windows 10

  • MS Office 2007 and higher


What if you have macOS

  • The users cannot download IRM-encrypted files using macOS devices. The only available option will be to download an encrypted PDF version for all supported formats.

  • IRM-encrypted files downloaded from the data room on a Windows PC can be opened on macOS devices using MS Office 2013. Other versions of MS Office on macOS are not supported.
