What is the best email encryption software for small enterprises using Office 365?

Hi community, 

What is the best email encryption software for small enterprises using Office 365? 

It needs to:

  • Support 20 users
  • Most staff are at remote sites
  • Staff are mostly technical but not IT experts
  • Needs to be robust 
  • Need to be easy to install and use 

Thanks! I appreciate the help.

In many years of working in secure environments, I have found a combination of MS BitLocker on the local machines O365 E3-E5 and adding on Barracuda Essentials https://www.barracuda.com/prod...   works great.

Encryption is only a very small part of protecting against cyber threats. Encryption in transit and Encryption at rest are important. But, most email threats and vulnerabilities are in the payload itself.  

Barracuda allows you to control what your users can send and receive via emails, has a plethora of other features and is affordable for small businesses.

The first question is what version of Office 365?  It may already be included...

Office Message Encryption or OME: https://docs.microsoft.com/en-...

  • Office 365 Message Encryption is offered as part of Office 365 Enterprise E3 and E5, Microsoft Enterprise E3 and E5, Microsoft 365 Business Premium, Office 365 A1, A3, and A5, and Office 365 Government G3 and G5. You don't need additional licenses to receive the new protection capabilities powered by Azure Information Protection.
