Office 365 uses encryption in two ways: in the service, and as a customer control. In the service, encryption is used in Office 365 by default. If you want to increase security level of messaging and protect extremely sensitive data we will provide implementation service to email encryption and rights protection capabilities.

Get secure email messaging implemented in your organization. With the new Office 365 Message Encryption (OME) capabilities, which leverage the protection features in Azure Information Protection, your organization can easily share protected email with anyone on any device. Users can send and receive protected messages with other Office 365 organizations as well as non-Office 365 customers using, Gmail, and other email services.

Our objective is to enable OME – Office 365 Message Encryption in your Office 365 tenant and provide instruments to control sensitive data with flexible policies or ad hoc customer controls that are built into Office 365.

An implementation project will be considered successful when you:

  1. start to send encrypted email from any device,
  2. easily navigate through encrypted messages,
  3. deliver encrypted email directly to recipients’ inboxes
  4. decrypt and read encrypted email with confidence, without installing client software.
  5. enjoy simplified user management that eliminates the need for certificate maintenance.
