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.
Amey Darekar - PeerSpot reviewer
Has an easy implementation phase to deal with for users
I primarily use the product in our daily security operations since it is implemented in all of our company's systems and is used in our environment. Normally, email security tools like FireEye or Trellix help to protect ourselves from spam, malware, and other email-oriented threats. The tool is used extensively in our company's environment. It is more like a collaboration email security that is used in our company. Whether my company plans to increase the number of users of the product or not is something that depends on the growth of the organization. I recommend the product to those who plan to use it. The product is stable and reliable, considering the results my company gets out of it. When it comes to Trellix or FireEye Endpoint Security (HX), the tools offer antivirus as well as the modern real-time security feature, which is used to automate the detection and protection of the endpoints against all the security threats that are currently there in the industry. I don't see any challenges with the integration part of the product, but since a different team manages it, I don't have visibility into it. In terms of the value offered by the product, the solution does help our company protect data and the complete infrastructure. I rate the tool a nine out of ten.

Quotes from Members

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

Pros

"The biggest advantage of Mimecast Email Security is its spam filtering. Its filtering feature is interesting."

Cons

"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."
"The solution's console interface was recently changed for the admins, but the previous one was much better because we could open tabs on it."
"They should improve the cookies management feature."
"Mimecast needs to reduce the number of false positive emails; a big pain point for us."
"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 attachment scanning feature doesn't work properly."
"The reaction time between a new threat being identified and Mimecast picking it up needs to be narrowed a bit."
"While it's quick and easy, the initial setup could be more user-friendly."
"I would like the solution to be able to automatically quarantine the malicious emails before getting to the user's mailbox and continue with regular email operations. This could result in the user clicking the email before the purge operation is completed."
"The solution must provide features to scan QR codes for threats."
"The custom tailoring is limited."
"The solution is not easy to set up. However, we have employees that have the knowledge that can do the difficult implementation. It would be better if the process was easier."
"I would like to see this solution become more flexible."
"In general, our company should make the tool more robust to protect our systems."
"There is a need for improved integration with totally different products, such as a rapid server."
"The reporting aspect of the solution needs improvement."
