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

"The most valuable features of the Cisco ESA have to do with the intelligence they provide us, as they respond quickly to any phishing attacks and threats on the system."
"The solution works well."
"Email service is one of the services that we offer at Galaxy, and Cisco ESA has improved our business so much that our customers want to maintain their business with us for email security, with over 500 domains on our email platform and improved profitability in everything."
"It does a great job of preventing spam, malware, and ransomware."
"For what you get for the product, the support, and the overall stability, it is definitely a good return on investment."
"It provided a platform to sell a service to customers."
"The strong point of the solution is that we hardly get any spam emails because of Cisco Secure Email."
"It integrates with Active Directory and we can limit specific users to using specific applications."
"It is stable and reliable."
 

Cons

"It is not user-friendly, and it is quite complicated. So, it should be more user-friendly."
"It takes time to harmonize information from the email log events with higher level reporting tools."
"The scalability must be improved."
"The configuration UI should be made more intuitive. Currently, it takes a while to understand how to do the basic configurations."
"The graphical user interface is not user-friendly like other vendors. I find it very difficult at times to find some options on the UI."
"Don't neglect that because if you just try to rely on Cisco support you're going to notice pretty consistent slowdowns."
"Cisco is already providing a very good environment with the IronPort solution, but there could be some more integration with other products. For instance, an integration with the EDR solution could be there to raise an alert."
"The area of license renewal should be improved. We normally renew our license every year."
"The solution could be less expensive."
 

Pricing and Cost Advice

"It is a relatively expensive option compared to other alternatives."
"I would rate the pricing a ten out of ten, where one is cheap, and ten is expensive."
"You're going to get what you pay for. If you're not willing to pay the price of Cisco, you're not going to get a product that's as good as Cisco. I don't think Cisco is overpriced, because for the last two years I've been comparing it to Microsoft and Cisco has been cheaper and given us more features."
"The licensing was all transferred."
"Pricing depends on your environment and which model you want to buy."
"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."
"In addition to the standard licensing, there is a cost for SMARTnet as well."
"I rate the product price as six on a scale of one to ten, where one means it is a very expensive tool."
