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.

Quotes from Members

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

Pros

"The cloud-based interface is very user-friendly."
"It is a solid and stable product."
"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."
"The solution is excellent at blocking spam."
"Symantec Messaging Gateway has a huge knowledge base about phishing, spamming, spoofing, etc."
"Symantec’s spyware and malware signature database is very good compared to other products."
"The feature that I like the best is the fingerprinting concept."
"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 technical support services are excellent."
"With Trend Micro email security gateway, we can deploy features like DLP and BEC."
"The solution provides protection with its Email Track Records and Machine Manual features."
 

Cons

"Symantec Messaging Gateway should include better exclusions and exceptions for better administration."
"Sometimes the solution picks up false positive for viruses during scans."
"Support could be better. What's also 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."
"This product would benefit from better integration with Symantec Endpoint Protection."
"Where it is not available, as is the case with unstructured data, this product fails miserably."
"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."
"Messaging Gateway's advanced malware detection could be improved."
"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."
"The product's pricing could be more flexible."
"There is room for improvement in content filtration, expressions, file sharing, and policy configuration."
"The solution's pricing could be improved."
 

Pricing and Cost Advice

"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."
"They're a little costly compared to Microsoft."
"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."
"For 150 users, we pay INR 1,60,000."
