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.

Quotes from Members

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

Pros

"The best feature of Barracuda Email Protection is that it provides protection for Microsoft 365."
"I would rate the solution nine out of ten."
"The archiving and search features are very good."
"I'm quite satisfied with the graphical user interface for Barracuda products."
"The solution is straightforward to set up."
"The most valuable aspect includes attempts to spoof or compromise domains from external sources."
"The beauty of Barracuda Email Protection is that it is easy to manage and simple to deploy."
"We now have a secondary backup of Office 365 that's much easier to retrieve compared to Microsoft. If someone deletes something in Office 365, we can get it back within Office 365, but it's difficult. Barracuda is much easier. There is a lot less management needed using Barracuda. The management becomes much easier for Office 365 and it's no longer on-prem, so there are fewer hours managing on-prem devices, servers, and things of that nature. We don't have network appliances anymore for the backup of our information."
"It offers an easy initial setup."
"The interface of this solution is very easy to navigate and user-friendly. There is no delivery in email and other communications, making it reliable. The configuration is relatively easy."
"We like Mimecast's spam filtering. The email signature feature is also a big plus for our users."
"URL inspection works pretty well."
"The initial setup is easy."
"The solution is scalable."
"In terms of efficacy, Proofpoint is better than Mimecast, though it's a little difficult to manage."
"The solution's performance is good."
 

Cons

"The policies are set up in Barracuda by default; we don't have any control over them."
"I would like to see some additional functionality in terms of employee monitoring, as part of a work-from-home security solution."
"The technology works on a supervised engine, but it would be better if it ran on an unsupervised engine."
"Sometimes it is somewhat laggy, especially on the Archiver side. It should have improved performance on their Message Archiver."
"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."
"They could simplify the licensing and the pricing."
"Two to three months back, we got fraudulent emails in which someone in the organization was being blamed."
"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."
"External security features need improvement."
"The reaction time between a new threat being identified and Mimecast picking it up needs to be narrowed a bit."
"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."
"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."
"We have subscribed to an archival service, and yet, when we have to get our data out, we have to pay a fee to get our own data. They charge an extraction fee."
"Mimecast needs to reduce the number of false positive emails; a big pain point for us."
"They could provide a unified licensing model, including all the security features."
 

Pricing and Cost Advice

"We didn't have to pay a lot for the solution because we got it from a good vendor with a good user volume."
"Despite a list price possibly around $40 per user, their market price allows customers to easily buy the solution."
"Price-wise, this product is middle-of-the-road."
"The product is expensive."
"Barracuda licensing model is good."
"The price is similar to that of Microsoft 365."
"We pay annually. They never charged us for anything else. And they were quite a bit under that $20,000 mark. It was $19,074. And they've been pretty good about not skyrocketing the price or anything like that. It has gone up. It's gone up to $24,000 in 2020."
"The solution's pricing is moderate, where it is neither cheap nor expensive."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the pricing a ten."
"Compared to the other products in the market, it is neither cheap but nor very expensive. I would rate it somewhere in the middle, 5 out of 10."
"We pay monthly fees to our provider."
"It is a bit expensive."
"The product has good pricing in terms of return on investment."
"Compared to the other solutions in the market, Mimecast Email Security with Targeted Threat Protection's pricing is fine."
"The customers can select the license packages as per their requirements."
"I'm always going to say the price needs to be lower, but it's reasonable."
