Email security has protected financial data and provides clear tracking for every branch message
The areas of Cisco Secure Email that could be improved or enhanced are the slowness in the console. I don't think it was a database error or something, but we feel some slowness in configuring DLP and other content filters compared to other consoles. It may have been due to on-premises, but it was much noisy at some times while configuring DLP. When we tried to configure a DLP policy, the console became much slower. In that case, we cannot see what had happened in the mail which was blocked at that time. It may take nearly an hour to get back to normal while configuring policies. That is the major issue in the product.

Quotes from Members

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

Pros

"It is doing its work. It is doing what it was actually designed to do. It has ensured we don't have business email compromises, and it has also ensured that our brand Galaxy is unique all year round."
"The filtering is definitely better at catching both spam and malicious messages, and there's a lot of extremely granular ability for setting up rules. You can do it the way you want to. The Microsoft solution tends to be pretty limited in how it allows some of that to be done."
"Introducing Cisco Secure Email Gateway systems was a set change for us and reduced the number of unwanted emails by a huge factor, a benefit that has continued from when we first got the devices until today."
"The system provides our service desk with the means to troubleshoot email delivery issues with ease."
"It provided a platform to sell a service to customers."
"My favorite feature of Cisco Secure Email is the threat intelligence capabilities, particularly its integration with Cisco Talos."
"The user interface was quite friendly, it was quite easy to use, unlike some other Cisco products. Anybody could use it. You don't have to be familiar with IT to be able to handle navigating it."
"The advanced phishing protection and the integration with the awareness tool that Cisco has embedded into the solution to bring awareness to the customers about the dangers of phishing attacks and other things that come from email are the most valuable features."
"It is stable and reliable."
 

Cons

"The interface is dated. It has looked pretty much the same for 15 years or so."
"The configuration UI should be made more intuitive. Currently, it takes a while to understand how to do the basic configurations."
"I would like to see features like AI since it is currently an area that the product lacks."
"Better dashboards and more interactive overviews would be nice, but the current functionality is sufficient."
"The reporting functionality needs to be improved."
"The user interface is a bit complex."
"We didn't get any malware, but a few phishing emails, maybe one or two, slipped in."
"The primary areas for improvement are the pricing and the complexity of deployment."
"The solution could be less expensive."
 

Pricing and Cost Advice

"It is not that costly. We pay for the solution through a contractor and pay an annual fee."
"There were no other costs in addition to the standard licensing fees."
"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."
"I would rate the pricing a ten out of ten, where one is cheap, and ten is expensive."
"There are additional fees for adding features."
"The price is significantly high."
"It is a reasonably priced solution."
"Cisco Secure Email is not expensive, and licensing costs are yearly."
