Their support should be improved. They are notorious for sending you to knowledge-based articles rather than actually talking to you, but that is, unfortunately, kind of becoming a trend with everything. In terms of features, I haven't had any complaints. However, I don't like the fact they moved to a paid training subscription model. They used to have a lot of free webinars for training, but they have started to charge for them in the past year.

From an administrative point of view, Mimecast is a little bit cumbersome and difficult. It's not something that the end-user can easily find navigate themselves.

While it's quick and easy, the initial setup could be more user-friendly.

The reaction time between a new threat being identified and Mimecast picking it up needs to be narrowed a bit.
