Frank Rawson - PeerSpot reviewer
It gives clients peace of mind and helps them educate their users about threats
A few years ago, our team found the implementation to be somewhat challenging. It has gotten easier as we've grown more experienced. The difficulty depends on the expertise of the person doing it. I don't work with Mimecast every day, so it might be more difficult for me than it is for one of my techs who regularly does Mimecast implementations. It requires some specific in-depth product knowledge and an understanding of email solutions. The deployment time varies. In South Africa, it depends on who you use to deploy it. If you use one of Mimecast's local partners, it can take up to two weeks because of their process. However, it's only about four to eight hours of work. After deployment, there isn't much maintenance aside from supporting and educating your customers. Users require constant education on how to use the Mimecast client and release an email that has been blocked.

Offers clear vision on the clear side of what is being blocked and easy to use but a bit old-fashioned GUI
I would rate my experience with the initial setup a four out of ten when one is difficult, and ten is easy. It's difficult initially since it's an on-premise solution. So it's a bit difficult. So the initial assessment took a few days, and then the deployment was a couple of days. It is on-prem. That is also one of the improvements you need to make on the cloud. Most of the people like things to be on the cloud. You don't have the burden of setting up things on-premise.
