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

"The solution is pretty straightforward to use and easy to set up."

"We're now certain business-critical mail is perfectly protected in multiple ways."
"Symantec Messaging Gateway is stable and scalable. Installation is easy, and the deployment and maintenance can be done by one administrative person."
"The most valuable feature of the solution is the content filtering policies because the solution offers huge options for configuration, such as hardware manipulation, et cetera, and the dictionaries make the work easier."
"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 most valuable features of Symantec Messaging Gateway are advanced content filtering, malware, and antivirus defense."
"It has very good capabilities for managing malware."
"The feature that I like the best is the fingerprinting concept."

Cons

"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 complex and not easy to use."
"Their support should be improved. They are notorious for sending you to knowledge-based articles rather than actually talking to you about the problem you're reporting."
"The solution is expensive in comparison to similar solutions."
"The interface isn't the best. How everything works on the back end is confusing."
"While it's quick and easy, the initial setup could be more user-friendly."
"While it's quick and easy, the initial setup could be more user-friendly."
"From an administrative point of view, Mimecast is a little bit cumbersome and difficult."
"Recently, I've had some problems regarding their support. The tech was acquired by Broadcom, and since then, the support part is very bad."
"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."
"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."
"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."
"In a later release, it would be nice if the messaging gateway supported the cluster feature."
"The product must improve the user dashboards."
"Sometimes the solution picks up false positive for viruses during scans."
"What needs to be improved in Symantec Messaging Gateway is its local partner support, as it's not as technical."
 

Pricing and Cost Advice

"It is a bit expensive."
"For what it is, the product is overpriced."
"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."
"The product price is moderate. I rate the pricing a five out of ten."
"The licensing costs are per-user for the product that you get with them."
"The product has good pricing in terms of return on investment."
"The price of Mimecast Mailbox Continuity is 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."
"They're a little costly compared to Microsoft."
"A subscription for technical support costs extra."
"Symantec Messaging Gateway’s pricing is very cheap."
"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."
"It's a bit expensive compared to its competitor Barracuda Email Security Gateway but cheaper than Sophos Email."
"For 150 users, we pay INR 1,60,000."
