LeeMiles - PeerSpot reviewer
Very good threat protection, spam filtering, and cloud backups
Considering it integrates with Azure, I would like to be able to effectively set up policies where people are by default included in certain settings. For instance, for email quarantine, I can't set up a global setting. Users must go through an induction session where I guide them in configuring quarantine alerts rather than having default settings based on group membership. This seems like an oversight since they already use Active Directory details. They should assign policies based on group membership, which configures these settings by default.
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.
