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.
PC
Stable, but malware needs improvement and customer support is poor
They need to improve the malware in the product. I am not satisfied with Clearswift because of the lack of customer support. The support is poor, the supplier takes a lot of time and it's expensive. We have some issues here when I contact the supplier, it takes a lot of time for them to get back to us but there's no solution. I am now looking at Symantec as a possible alternative.

Quotes from Members

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

Pros

"It has an intuitive, clear graphical interface where you can deploy your policies and understand the overall flow. There are a lot of things that you cannot handle on the graphic interface, like message filters. For this, you need to go to a lower level where you have more power, like command line interface. So, this solution has the best of both worlds. There are not a lot of bells and whistles. It is more practical with access to most features that you can configure."
"Cisco Secure Email is part of Cisco's extensive efforts and investments in technology, especially in the realm of cyber security. The product is one among many security solutions offered by Cisco."
"There is a huge return compared to if we didn't have a gateway appliance, as far as blocking malicious emails."
"The most significant enhancement we've gained is in terms of security through the upgrade we received."
"The product's initial setup phase was easy."
"Cisco Secure Email is a budget-friendly solution."
"There were detailed logs available. That was a seriously good feature... It turns out these were actually spoof emails that came into our environment. I got to know about them from the log system."
"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."
"A stable solution."
"Ability to create your own content-filtering policies with relative ease."
 

Cons

"It would be nice to have an easier way to check on the health of the system, how stressed these appliances are. Sure, you can do it, but it would be helpful to have an easier way to do it, maybe even at a glance."
"Licensing is quite complicated for a number of customers, including ourselves."
"The scalability must be improved."
"We have Microsoft and we have the E5 licenses, they have more EDR responses on certain emails. That's something that Cisco ESA on the cloud doesn't have. They don't do anything about MITRE attacks. They only detect if there is a malicious email or a threat and they remove it."
"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 cannot manage multiple devices from a single UI."
"We would like to see more options for the customization of content filters."
"The user interface of the Email Security Gateway should be improved."
"Malware needs improvement."
"FTP server and TRUST Manager functionality."
 

Pricing and Cost Advice

"It is a relatively expensive option compared to other alternatives."
"Cisco Secure Email and the support are priced well. It's not cheap, but there are other solutions that offer less and cost so much. For example, Microsoft is more expensive than Cisco."
"In addition to the standard licensing, there is a cost for SMARTnet as well."
"I don't have the insights into it, but compared to different products, it seems to have a medium level of pricing."
"It's adapted to the market. It's similar to other vendors. We at least don't have many problems regarding that because Cisco is adaptable on that side. When we present the solutions to the customers, we tend to achieve the goals that the customer has in terms of the budget for such implementations."
"Licensing costs depend on how many users there are. It could range between $5 and $7 per month, per user."
"The solution is expensive."
"The product's price falls on the higher side when compared to the other products on the market."
