Featured Reviews

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.

A simple and easy-to-handle solution that does not need multiple configurations, but its pricing could be improved
Trustifi Inbound Shield is a simple and easy-to-handle solution where we don't have to go for multiple configurations. A single IT admin supporting over 100 or 200 users can easily understand everyday reports. Trustifi Inbound Shield is a user-friendly solution that even simple lay people can understand. The product helps our customers avoid 95% of unwanted phishing emails.

Quotes from Members

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

Pros

"The solution is pretty straightforward to use and easy to set up."
"The initial setup is easy."
"The biggest advantage of Mimecast Email Security is its spam filtering. Its filtering feature is interesting."
"Based on overall experience, Mimecast Email Security is the best solution for traditional gateways."
"We like Mimecast's spam filtering. The email signature feature is also a big plus for our users."
"The setup was easy."

"Trustifi Inbound Shield is a simple and easy-to-handle solution where we don't have to go for multiple configurations."
 

Cons

"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."
"Lately, Mimecast's outbound mail servers have been regularly blocklisted by spam filters. That didn't happen a few years back, but it seems to be a more frequent problem these days. When a server is blocklisted, it means all of my outgoing mail ends up in the recipient's junk mail. That affects my reputation and business confidence."
"The installation is not so straightforward."
"Its pricing can be improved. It is a bit expensive."
"The reaction time between a new threat being identified and Mimecast picking it up needs to be narrowed a bit."
"I'd like to have better support from the product in the future."
"Many of our users complain that the system is blocking too many attachments. It's a good practice from a security perspective, but our users think Mimecast is doing too much. It might be something we'll have to adjust."
"The solution's pricing is very high compared to other products like Barracuda and should be improved."
