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.

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.

Quotes from Members

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

Pros

"The solution offers good technical support."
"The initial setup is very straightforward."
"It offers an easy initial setup."
"The initial setup is easy."
"In the current environment that the world is in, everyone is trying to hack everyone else, so Project+ definitely helps a lot there."
"The product is good. To date, we have not faced any challenges."
"The security is pretty good, and that's why we're going to upgrade to an even more advanced package. We used it when we had a power issue, and it works. It has been pretty reliable, and the support has been quite good."
"The piece that is most valuable from the Mimecast standpoint will be the sandboxing feature."
"Symantec Messaging Gateway is stable and scalable. Installation is easy, and the deployment and maintenance can be done by one administrative person."
"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."
"The setup is pretty simple."
"The solution is "set and forget". You pay for it and everything is done for you."
"I like that it's simple and easy to configure, deploy, and manage. The reporting function has all the features we're looking for, and we are fine with that."
"It is a solid and stable product."
"The most valuable features of Symantec Messaging Gateway are advanced content filtering, malware, and antivirus defense."
"Messaging Gateway is stable."
 

Cons

"The price could be better, it should be reduced."
"The detection rates are an area for improvement."
"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 filtering needs more flexibility."
"As a user, the user interface of the management console could be upgraded, for example."
"From an administrative point of view, Mimecast is a little bit cumbersome and difficult. It's not something that the end-user can easily find navigate themselves."
"Mimecast Email Security is somewhat expensive compared to the competition in the Indian market, and the local presence is lacking as they do not have a local representative currently."
"The solution is expensive in comparison to similar solutions."
"Symantec Messaging Gateway can improve detection because most of them are false negatives or false positives that we are trying to troubleshoot. Additionally, we are having routing problems and they are somehow connected to DNS issues."
"In a later release, it would be nice if the messaging gateway supported the cluster feature."
"Sometimes the solution picks up false positive for viruses during scans."
"The solution interface is from 2003 and is outdated. Symantec Messaging Gateway needs to update the interface."
"What needs to be improved in Symantec Messaging Gateway is its local partner support, as it's not as technical. The support my company gets from the partner isn't good. Vendor support is good, but local partner support isn't. I'm happy with Symantec Messaging Gateway as a solution, but the problem is with its partner support. To me, Symantec Messaging Gateway is a complete solution, but it can be very difficult to search the web for resolutions to issues or problems you experience from it. If this could be improved or resolved in the next release of Symantec Messaging Gateway, then that would be good."
"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."
"This product would benefit from better integration with Symantec Endpoint Protection."
"We've had issues in the past where the user finds spam, and Symantec does not recognize it as spam."
 

Pricing and Cost Advice

"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."
"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."
"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."
"It is a bit expensive."
"I'm always going to say the price needs to be lower, but it's reasonable."
"It's an expensive solution."
"The product has good pricing in terms of return on investment."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the pricing a ten."
"For 150 users, we pay INR 1,60,000."
"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."
"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."
"Symantec Messaging Gateway’s pricing is very cheap."
