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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The most important feature is data processing."
"The solution is scalable."
"It does a good job for us, and its admin console is easy to use."
"In the current environment that the world is in, everyone is trying to hack everyone else, so Project+ definitely helps a lot there."
"Due to our specialized use case, that HIPAA dictionary really comes in handy."
"The initial setup is very straightforward."
"Email security is the most valuable feature of the solution."
"The biggest advantage of Mimecast Email Security is its spam filtering. Its filtering feature is interesting."
"In terms of efficacy, Proofpoint is better than Mimecast, though it's a little difficult to manage."
 

Cons

"The pricing for personal users is not cost-effective."
"The price could be better, it should be reduced."
"The product's interface could be improved to be more user-friendly."
"They could provide a unified licensing model, including all the security features."
"I did have a problem with Mimecast. That is why I was looking for an alternative solution because their sender IP address gets poorly rated by Microsoft."
"Mimecast need to ensure that the body text format is correctly handled and that images are properly embedded in the body text."
"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."
"The feature that should be included is to remove the block on the encrypted files."
"The detection rates are an area for improvement."
