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

"There is a huge return compared to if we didn't have a gateway appliance, as far as blocking malicious emails."
"The strong point of the solution is that we hardly get any spam emails because of Cisco Secure Email."
"The tool has a DLP solution which we can implement. Its database is updated regularly."
"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."
"The logs are easily readable and help diagnose problems, although they can be difficult to find initially. The solution addresses our email security, but for the rest of our security, we would use multiple vendors. It covers everything through email, like antivirus, IDS, and IPS."
"It has the ability to tell us, after an email has been delivered, where else it went, once it got inside. Maybe it's something we wanted it to stop and it didn't stop it, but it notified us later that it was something that it should have stopped. It can give us a trajectory of all the other places that it went internally and it can tell us what files were transferred as well."
"Initially, the most valuable feature for us was the SenderBase Reputation, because that reduced the number of emails that were even considered by the system by a huge number..."
"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 is stable and reliable."
 

Cons

"I am not satisfied with the solution's reporting and logging."
"The Forged Email Detection feature needs improvement, particularly with domain. The sensors are not that good and the rules sets are unclear."
"We have occasionally had hardware problems because we are using an appliance-based solution, but that might change. We may consider going to virtual systems."
"Cisco Secure Email can be improved from the administrator's point of view. Usually, you have to work with different areas, and they can try to make it easy for the administrator to use different functions."
"Licensing is quite complicated for a number of customers, including ourselves."
"It takes time to harmonize information from the email log events with higher level reporting tools."
"I would like to see sandboxing for email, where suspicious emails received by the system are analyzed through online services."
"I would like more functionality and how to use it for Level 2 type staff. The biggest issue is it needs to be easier to use and navigate."
"The solution could be less expensive."
 

Pricing and Cost Advice

"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."
"In addition to the standard licensing, there is a cost for SMARTnet as well."
"It is a super big router that costs a few hundred thousand dollars."
"I rate the product price as six on a scale of one to ten, where one means it is a very expensive tool."
"I don't have the insights into it, but compared to different products, it seems to have a medium level of pricing."
"We do annual licensing for Cisco Secure Email Gatewayand SMA together, and possibly SmartNet support. Packaged together, the cost is just under $38,000."
"The product's price falls on the higher side when compared to the other products on the market."
"Pricing depends on your environment and which model you want to buy."
