Thanks Caroline Shin, great article.
As a very small business, we currently only use Business Essentials and Business Premium, but we deal with some very sensitive client information which we should be sharing using encryption. Unfortunately, from everything I've read and the sales people I've spoken to at MS, data protection offerings such as the ones you've outlined here are geared towards big business / enterprises. What would you recommend for small businesses, who work under exactly the same data protection laws as major enterprise organisations, with regards encrypting emails and so on? The key for us is to keep it all as hosted, online solutions as part of O365 as we do not have our own IT department or infrastructure.
Really hoping you can help as despite lots of research I've not yet been able to come up with a workable, affordable solution.
Many thanks in advance, Oz
