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 technical support from Cisco is perfect."
"You are never secure without some solution from Cisco."
"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 tech engineers are very knowledgeable."
"The system provides our service desk with the means to troubleshoot email delivery issues with ease."
"The most valuable features are Advanced Malware Protection, URL filtering, and of course Reputation Filtering."
"IronPort allows visibility into the problem and an easy way to pinpoint policy offenders."
"The system enables end users to manage their own whitelists/blacklists."
"It is stable and reliable."
 

Cons

"I use the search all the time. Sometimes, it is hard to search for things and things are hard to find."
"The UI is definitely one area of improvement because it doesn't match other interfaces and the navigation can be a little clunky."
"The user interface is a bit complex."
"One of the things that Cisco could improve on with IronPort is the support."
"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."
"They can do it better with web links, with the URLs."
"Having Cisco Email Security as a standalone solution is not good enough. It needs to be combined with another solution."
"Better dashboards and more interactive overviews would be nice, but the current functionality is sufficient."
"The solution could be less expensive."
 

Pricing and Cost Advice

"I would rate the pricing a ten out of ten, where one is cheap, and ten is expensive."
"In addition to the standard licensing, there is a cost for SMARTnet as well."
"Cisco Secure Email is not expensive, and licensing costs are yearly."
"I rate the product price as six on a scale of one to ten, where one means it is a very expensive tool."
"There are additional fees for adding features."
"It is an expensive product. I rate its pricing an eight or nine."
"The solution is expensive."
"Cisco Secure Email is more expensive than other products. I rate it a five out of ten. There are no additional costs. You only need to pay the subscription amounts."
