Helps prevent security breaches but fails to improve in the area of AI
I have not noticed any impressive advanced threat protection mechanisms in the tool. I don't know if there are any AI features in the product. I don't know if there is any other technology embedded in the solution. Cisco Secure Email successfully mitigated potential email threats. My company has seen plenty of scenarios where Cisco Secure Email successfully mitigated potential email threats, spam emails, and fraudulent domains. The product is good for dealing with spam emails, and it can take care of more than 100 spam emails per day. A huge number of spam emails are monitored with the help of Cisco Secure Email. I would not recommend the product to other businesses because you need to have some kind of expertise in configuring and knowing a bit about the tool's GUI. The tool also lacks in the area of AI mechanics. If I would like to have an overview and review another solution, I would go for another product other than Cisco Secure Email. I can definitely suggest others to look at the product and review it, but I would also recommend that they compare it with the other solutions in the market. I wouldn't prioritize Cisco Secure Email over other tools. Either the support partner of the product or I take care of the tool's maintenance phase by looking into the configurations and doing some fine-tuning. I rate the tool a seven to eight out of ten.

Handles security, malware and spam of email systems
We use Email Security Gateway on email systems for handling security, malware, and spam.  The solution is easier to manage than FortiMail. You can implement policies easily.  The solution does not always effectively identify zero day spam and phishing, but once reported the correction occurs very…

Quotes from Members

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

Pros

"Anti-Spam and Advanced Malware Protection are the most valuable features... and we also have the option to block Zero-day attacks."
"It has the IMS engine, Intelligent Multi-Scan engine, and it does a good job, right out-of-the-box, of blocking the vast majority of things that should be blocked."
"The security features are valuable."
"What I find the most valuable about Cisco Secure Email is that the logs are not that difficult to see even if you're not used to them. The logs are reasonably readable and diagnosing the problem is not too hard with them."
"It is a user-friendly product."
"It provided a platform to sell a service to customers."
"The system provides our service desk with the means to troubleshoot email delivery issues with ease."
"The tech engineers are very knowledgeable."
"It helps reduce spam and phishing attacks."
"The solution is easier to manage than FortiMail. You can implement policies easily."
 

Cons

"The discontinuation of physical hardware solutions is a significant area for improvement in Cisco Email Security Appliance. This decision has posed challenges as virtual appliances are now the only option, which may not be suitable for all industries. The uncertainty regarding the future of the hardware aspect of the solution is a notable concern."
"The interface is dated. It has looked pretty much the same for 15 years or so. It would be helpful to be able to do everything from one spot. The centralized quarantine and reporting are completely separate from policy administration."
"I would like them to add some clustering or high availability features."
"We didn't get any malware, but a few phishing emails, maybe one or two, slipped in."
"The reporting functionality needs to be improved."
"I use the search all the time. Sometimes, it is hard to search for things and things are hard to find. People come to me all the time, saying, "This email didn't get through." Then, I go searching and don't find it on the first search. You have to think about alternative searches. I don't know if there is an easier way that they could help to find things. I don't know how they could simplify it, because now everybody else is using the cloud and everything is coming from Office 365, or whatever. It is just not the same environment from years ago where everybody had their own server and you could search easier."
"They can do it better with web links, with the URLs. They have a technology called Outbreak but it doesn't work as well as we would like."
"We would like to see more options for the customization of content filters."
"The solution does not always effectively identify zero day spam and phishing, but once reported the correction occurs very quickly."
"Its pricing could be affordable."
 

Pricing and Cost Advice

"I rate the pricing a ten out of ten on a scale where one means it is less cost-effective, and ten means it is the most cost-effective solution."
"The licensing was all transferred."
"Compared to Cisco's on-prem service, the cost is the same, but you don't have to pay for the hardware and you don't have to maintain the system, as far as upgrades and hardware failures are concerned. It is cheaper to operate on their cloud service than it is to operate with their on-prem service."
"The licensing is a mess and needs sorting out. I am not really concerned about the pricing because I only make recommendations, not buying decisions."
"Cisco Secure Email is not expensive, and licensing costs are yearly."
"Cisco Secure Email is expensive, but we get what we pay for."
"At times, we feel the pricing is a bit too high, but then, there is also room for discounts. We enjoy a lot of discounts, and that is why we are still with them. There are no costs in addition to the standard licensing fees."
"Licensing costs depend on how many users there are. It could range between $5 and $7 per month, per user."
"Email Security Gateway's pricing is good."
