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

"For what you get for the product, the support, and the overall stability, it is definitely a good return on investment."
"I can customize the configuration and policies."
"The most significant enhancement we've gained is in terms of security through the upgrade we received."
"We like the in-built features, like the email filtering based on the IP and domain, and Cisco has its own blacklisted domains and IPs, which is very good because this filters around 70 percent of emails from spam and we are seeing fewer false positives with this."
"It provided a platform to sell a service to customers."
"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."
"Even though it's not perfect, 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 solution is valuable if you are looking for a security email gateway that provides you with the most services possible."
"It is stable and reliable."
 

Cons

"It is not user-friendly, and it is quite complicated. So, it should be more user-friendly."
"We have been struggling in the last month with Cisco encryption and with the S/MIME encryption. I don't know if it is an issue on our side or if these features of the solution are not working very well."
"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."
"That's why I wouldn't give it anywhere near a perfect score, because the artificial intelligence just isn't there yet."
"The user interface needs some improvement to become more user-friendly. The graphics could be better. It's designed more for a technical user rather than a business user."
"The areas of Cisco Secure Email that could be improved or enhanced are the slowness in the console."
"The configuration UI should be made more intuitive. Currently, it takes a while to understand how to do the basic configurations."
"The primary areas for improvement are the pricing and the complexity of deployment."
"The solution could be less expensive."
 

Pricing and Cost Advice

"The pricing is good."
"I would rate the pricing a ten out of ten, where one is cheap, and ten is expensive."
"I rate the product price as six on a scale of one to ten, where one means it is a very expensive tool."
"The licensing was all transferred."
"Pricing depends on your environment and which model you want to buy."
"The product's price falls on the higher side when compared to the other products on the market."
"Cisco Secure Email is expensive, but we get what we pay for."
"The pricing for the Cisco Email Security Appliance involves recurring costs for licenses based on the contracted time frame, such as one year, three years, or five years. Renewals are required after the license expires."
