HS
Email Security Engineer at Logic Infosecurity
Experience high detection and user-friendly policies with reliable email security implementation
The system is not user-friendly because you have to create policies that are mapped in a dictionary. As an IT engineer, I understand how it works, but explaining it to another IT person can be difficult. Having more user-friendly dashboards would improve the work experience. In Mimecast Email Security, checking policies in the dictionary or gateway is very complicated, and not everyone understands this process. If you examine the Check Point portal, it's user-friendly with easily accessible tabs that anyone can explore. With Mimecast Email Security, making changes might impact existing mailboxes. The portal is complicated compared to Check Point's user-friendly interface.

System Administrator at emco Bautechnik GmbH
Effectively reduces spam and malicious emails with reliable detection capabilities
It would be helpful to make it easier for end users to filter and see items in the quarantine within the Proofpoint Intelligent Compliance Platform. As an admin, I believe it would be sensible if end users could also see the quarantine folder in the Proofpoint Intelligent Compliance Platform so they can create their own rules. The reports are all predefined, and I cannot create custom reports, so I am not fully satisfied with their visibility. I would appreciate the ability to generate my own reports.

Quotes from Members

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

Pros

"My advice to those considering this product would be to go for it."
"In terms of efficacy, Proofpoint is better than Mimecast, though it's a little difficult to manage."
"Its administration console is very easy to use. The administration console is absolutely important because you interact with the platform through it."
"I recommend Mimecast based on customer requirements and budget."
"Based on overall experience, Mimecast Email Security is the best solution for traditional gateways."
"I would rate Mimecast Email Security a nine out of ten."
"The product is good. To date, we have not faced any challenges."
"It's really quite user-friendly. In terms of technical superiority and the product itself, there are no complaints. It is really cutting edge."
"Our experience with the platform has been positive as it has maintained consistent control over spam and malware threats."
 

Cons

"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 detection rates are an area for improvement."
"Mimecast needs to reduce the number of false positive emails; a big pain point for us."
"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 attachment scanning feature doesn't work properly."
"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 lock in is very, very tight. It is impossible to move out of Mimecast to a different product, like Proofpoint or 365 ATP, and keep the chain of custody for every email that I've archived."
"This solution can be frustrating. It blocks many things that should be going through."
"The Proofpoint Intelligent Compliance Platform does not provide features that help reduce manual efforts, so additional human resources are still required to manage security."
 

Pricing and Cost Advice

"The solution is expensive."
"For what it is, the product is overpriced."
"The price of Mimecast Mailbox Continuity is expensive."
"I'm always going to say the price needs to be lower, but it's reasonable."
"Its price is in the middle range. It is a structured licensing model where there are various components that you can add or choose to add or not."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the pricing a ten."
"The product price is moderate. I rate the pricing a five out of ten."
"The customers can select the license packages as per their requirements."
