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.
Girish Vijay - PeerSpot reviewer
Deputy Manager IT at Carl Bechem Lubricants India Pvt. Ltd.
A stable and reasonably priced solution that performs well and has a very good malware database
Since Symantec merged with Broadcom, they might have lost some good technical engineers. Maybe that’s the reason why the product is performing poorly. When we have a good marketing and sales team, even though our product cannot perform, we will sell it at a high price because of the buzzwords. However, at the end of the day, the product should perform. Most of the products might not perform. Symantec is a very good product, but the services are basic. I rate the technical features of the product a nine out of ten. However, I would rate the services provided by the solution a six out of ten. Overall, I rate the tool an eight out of ten.

"Mimecast has some good support services in place."
"It's really quite user-friendly. In terms of technical superiority and the product itself, there are no complaints. It is really cutting edge."
"We like Mimecast's spam filtering. The email signature feature is also a big plus for our users."
"In the current environment that the world is in, everyone is trying to hack everyone else, so Project+ definitely helps a lot there."
"The solution is scalable."
"It does a good job for us, and its admin console is easy to use."
"It is a solid and stable product."
"What I like most about Symantec Messaging Gateway is its usability. I also find its interface very friendly. The solution has a very good interface."

Cons

"The installation is not so straightforward."
"The feature that should be included is to remove the block on the encrypted files."
"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 reaction time between a new threat being identified and Mimecast picking it up needs to be narrowed a bit."
"As a user, the user interface of the management console could be upgraded, for example."
"The solution is very expensive."
"The solution is complex and not easy to use."
"External security features need improvement."
"It is a nice product but is not user friendly in terms of the graphical interface. It is poor and is not rich in terms of the human interface."
"What's lacking when you compare it with Proofpoint and other threat protection solutions is that it does the basic stuff, but we need more advanced threat handling."
"The solution interface is from 2003 and is outdated. Symantec Messaging Gateway needs to update the interface."
"The biggest problem is it's an on-prem product and we're trying to get out of having equipment in data centers."
"They have updated the version of the Messaging Gateway and the new features they are adding the need to be re-evaluated. They have done some changes on the policy."
"Sometimes the solution picks up false positive for viruses during scans."
"The false positive submissions must be improved."
"We've had issues in the past where the user finds spam, and Symantec does not recognize it as spam."
 

Pricing and Cost Advice

"For what it is, the product is overpriced."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the pricing a ten."
"The licensing costs are per-user for the product that you get with them."
"It's an expensive solution."
"It is a bit expensive."
"Two subscription options are currently offered: monthly and yearly. My suggestion is to opt for the yearly subscription as it can give some discount. The pricing isn't high as other cloud solutions are pricier than Microsoft's offerings."
"The price of Mimecast Mailbox Continuity is expensive."
"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."
"They're a little costly compared to Microsoft."
"The cost of Symantec Messaging Gateway is too expensive in general. However, the appliance also includes the price of the license in the same bundle."
"For 150 users, we pay INR 1,60,000."
"Symantec Messaging Gateway’s pricing is very cheap."
"A subscription for technical support costs extra."
"It's a bit expensive compared to its competitor Barracuda Email Security Gateway but cheaper than Sophos Email."
