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

"I have been satisfied with Mimecast Email Security as a good solution."
"The solution is pretty straightforward to use and easy to set up."
"The product's most valuable features are impersonation protection and phishing countermeasures."
"We like Mimecast's spam filtering. The email signature feature is also a big plus for our users."
"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."
"Based on overall experience, Mimecast Email Security is the best solution for traditional gateways."
"Its administration console is very easy to use. The administration console is absolutely important because you interact with the platform through it."
"The setup is pretty simple."
"Symantec is a secure product."
"Symantec Messaging Gateway has a good GUI, and it is very powerful in detecting viruses and spam."
"The solution is "set and forget". You pay for it and everything is done for you."
"It is a solid and stable product."
"It has very good capabilities for managing malware."
"The anti-malware and spam features are valuable."
"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

"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."
"We discussed the phishing aspect, the DNS system, and the key rotation."
"The solution is expensive in comparison to similar solutions."
"The interface and the documentation could be improved. They can also include some more training resources and content like video. While setting things up, I had to search for the information quite a bit. It took me time to find the correct way to do something. The information is there, but it is sort of all over the place. They can create a better help knowledge base or help portal. It retains your email for 45 days. They can maybe increase this duration."
"The price could be better, it should be reduced."
"The solution should include more AI features instead of Mimecast's more general static configuration tooling."
"Its pricing can be improved. It is a bit expensive."
"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."
"In a later release, it would be nice if the messaging gateway supported the cluster feature."
"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."
"It could be more scalable."
"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 false positive submissions must be improved."
"The solution takes up a lot of memory."
"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."
"The product price is moderate. I rate the pricing a five out of ten."
"I'm always going to say the price needs to be lower, but it's reasonable."
"The customers can select the license packages as per their requirements."
"It's an expensive solution."
"The solution is expensive."
"The licensing costs are per-user for the product that you get with them."
"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 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."
"It's a bit expensive compared to its competitor Barracuda Email Security Gateway but cheaper than Sophos Email."
"They're a little costly compared to Microsoft."
"A subscription for technical support costs extra."
"Symantec Messaging Gateway’s pricing is very cheap."
