Featured Reviews

Dennis O'Reilly - PeerSpot reviewer
Cyber SecOps Principal at Dotcom Security
The product provides good content filtering options, but the false positive submissions must be improved
The tool is very stable. I rate the stability a seven out of ten. It's an on-premise application that runs on a virtual machine. It has dependencies on the hypervisor host that we're running it on. If it's not configured, the application can be influenced by it. Sometimes, there is a service stop error while the service is still running. Sometimes, the service just stops. Some policies do not act the way that we intend them to respond.
John Zupancic - PeerSpot reviewer
Vice President / Branch Manager / Senior Technician at Aperion Information Technologies, Inc.
Inexpensive, with good email security, but the technical support could be improved
We don't have as many problems with email security. They have some areas that could be improved. For example, we also use this solution for email encryption, which was clunky and could be improved, but the email security itself has been excellent. The web interface works well but the Outlook plug-in has been problematic. We've had to uninstall/reinstall it. On some Outlook clients (including mine), it causes Outlook to stop responding. I disabled the Outlook plug-in and only use the web interface.

Quotes from Members

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

Pros

"Symantec Messaging Gateway has a good GUI, and it is very powerful in detecting viruses and spam."
"Symantec’s spyware and malware signature database is very good compared to other products."
"Since Symantec Messaging Gateway is a Linux-based solution it is stable."
"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 feature that I like the best is the fingerprinting concept."
"The main thing that I appreciate about this product is that the database of spam, malware, and ransomware is very large."
"The solution is a leader in anti-spam email products and you can block 99% of spam emails, making it very effective with great performance."
"The anti-malware and spam features are valuable."
"They do a better job of determining what's real and what's not than most of the other solutions we have tried, and it's been very painless to use."
 

Cons

"The documentation could have more detailed examples of how to use the product in various situations. As more companies shift to the cloud, they could better integrate the on-prem and cloud versions through an on-prem client."
"It could be more scalable."
"The solution takes up a lot of memory."
"It will provide Excel reports and PDF reports, but it would be great if they supported the concept of Crystal Reports."
"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."
"They really need to create a good package that competes with Microsoft."
"Since it was purchased by Broadcomm, we've found there's been a general slide in terms of the local services we have access to and we are considering replacing them."
"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 some areas that could be improved. For example, we also use this solution for email encryption, which was clunky and could be improved, but the email security itself has been excellent."
"Because the encryption has been very clunky, I would rate Zix Email Encryption a seven out of ten."
 

Pricing and Cost Advice

"A subscription for technical support costs extra."
"For 150 users, we pay INR 1,60,000."
"They're a little costly compared to Microsoft."
"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."
"In terms of pricing, I believe they provide excellent value."
