Securing Your Email
Before the explosion of cloud technologies, organizations had control over their data that resided within the perimeter of their on-premises data centers. The identity of the users, the devices they used, the applications they ran, and the company data were all confined within this parameter and controlled by the IT team.
Nowadays, however, we operate in a boundary-less world. We check email from our personal devices, we do our work at the office or at home — or even at the beach — and we use cloud services outside the perimeter of an organization’s data center. We do these things because we want to be productive, but sometimes this productivity can mean sacrificing security.
In Office 365, you can continue to do the things you do to be productive while at the same time stay secure. In Exchange Online (the technology driving your email), for example, you can encrypt your email so that only the intended recipi- ents of the message will be able to read it. You can apply protection to your email so if it’s confidential, the email can only be read by people within your organiza- tion. If someone accidentally forwards or copies a recipient outside of the organi- zation on email marked confidential, that recipient will get the email but he or she won’t be able to read it.
These security features for protecting email are available through the Office 365 Message Encryption (OME) service.
