Frank Rawson - PeerSpot reviewer
It gives clients peace of mind and helps them educate their users about threats
A few years ago, our team found the implementation to be somewhat challenging. It has gotten easier as we've grown more experienced. The difficulty depends on the expertise of the person doing it. I don't work with Mimecast every day, so it might be more difficult for me than it is for one of my techs who regularly does Mimecast implementations. It requires some specific in-depth product knowledge and an understanding of email solutions. The deployment time varies. In South Africa, it depends on who you use to deploy it. If you use one of Mimecast's local partners, it can take up to two weeks because of their process. However, it's only about four to eight hours of work. After deployment, there isn't much maintenance aside from supporting and educating your customers. Users require constant education on how to use the Mimecast client and release an email that has been blocked.
Girish Vijay - PeerSpot reviewer
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's performance is good."
"The initial setup is very straightforward."
"It offers an easy initial setup."
"We like the content filtering and secure messaging features."
"The solution offers good technical support."
"The product's most valuable features are impersonation protection and phishing countermeasures."
"The biggest advantage of Mimecast Email Security is its spam filtering. Its filtering feature is interesting."
"The solution is scalable."
"Symantec is a secure product."
"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."
"The feature that I like the best is the fingerprinting concept."
"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."
"Symantec Messaging Gateway has a good GUI, and it is very powerful in detecting viruses and spam."
"The solution is highly customizable. You can make rules for domains and configure policies for spam or malware. Messaging Gateway is an on-prem solution, so it's useful for companies without a cloud presence."
"The solution is excellent at blocking spam."
"The solution is "set and forget". You pay for it and everything is done for you."
 

Cons

"The solution is very expensive."
"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 platform's cost-effectiveness could be improved."
"Mimecast needs to reduce the number of false positive emails; a big pain point for us."
"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."
"External security features need improvement."
"I'd like to have better support from the product in the future."
"The filtering needs more flexibility."
"Symantec Messaging Gateway should include better exclusions and exceptions for better administration."
"Sometimes the solution picks up false positive for viruses during scans."
"Messaging Gateway's advanced malware detection could be improved."
"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."
"The false positive submissions must be improved."
"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."
"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."
 

Pricing and Cost Advice

"The solution is expensive."
"The customers can select the license packages as per their requirements."
"The product has good pricing in terms of return on investment."
"We pay monthly fees to our provider."
"The licensing costs are per-user for the product that you get with them."
"It's an expensive solution."
"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."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the pricing a ten."
"A subscription for technical support costs extra."
"For 150 users, we pay INR 1,60,000."
"They're a little costly compared to Microsoft."
"It's a bit expensive compared to its competitor Barracuda Email Security Gateway but cheaper than Sophos Email."
"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."
"Symantec Messaging Gateway’s pricing is very cheap."
