Featured Reviews

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.

Cons

"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."
"Barracuda Essentials can improve by continually adding more features."
"Two to three months back, we got fraudulent emails in which someone in the organization was being blamed."
"There is room for improvement, particularly in reaching out to technical support during deployment."
"Sometimes it is somewhat laggy, especially on the Archiver side. It should have improved performance on their Message Archiver."
"The solution's reporting mechanism is a little poor and could be improved."
"The customer service and support could be improved if the support were available directly in Europe. Currently, the support is often managed from India, so we sometimes need to wait due to the time zone difference. It would be quicker and better if the support were provided by European staff."
"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."
"The attachment scanning feature doesn't work properly."
"The tool can be challenging because it relies on rule-based configurations, especially for addressing impersonation threats. This approach requires setting up numerous rules to ensure filtering. It should work based on behavior-based analytics."
"The solution is very expensive."
"They should improve the cookies management feature."
"While it's quick and easy, the initial setup could be more user-friendly."
"As a user, the user interface of the management console could be upgraded, for example."
