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's definitely worth looking at Cisco's cloud email security offering; it's surprisingly simple to get going with, it really is easier to use than the on-prem because of everything they have built into it, and it is surprisingly cost-effective."
"The most valuable features are Advanced Malware Protection, URL filtering, and of course Reputation Filtering."
"The system provides our service desk with the means to troubleshoot email delivery issues with ease."
"The most valuable feature is the different content filters we are using, such as DKIM."
"Spam controls are excellent because they are a powerful feature that operates almost effortlessly."
"Cisco Secure Email has strong inbound services."
"The solution is very configurable. It has enabled us to configure some specific filters to stop emails that general configurations didn't stop. It's a powerful solution. It can analyze a lot of emails simultaneously, with no problems of capacity or system load."
"IronPort allows visibility into the problem and an easy way to pinpoint policy offenders."
"It is stable and reliable."
 

Cons

"They can do it better with web links, with the URLs."
"I use the search all the time. Sometimes, it is hard to search for things and things are hard to find."
"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."
"The area of license renewal should be improved. We normally renew our license every year. There is a feature called smart licensing, and I switched from the legacy mode to the smart licensing mode because of what I thought smart licensing does. I thought it would make licensing renewal seamless and very swift, but ever since I've switched to smart licensing, each time I want to renew my license, it is a whole lot of headache. The process is not smooth, and I had to keep calling Cisco TAC to see how the issue can be resolved. At one point, I wanted to revert back to the legacy mode, but I can't revert. Once you switch from the legacy mode to the smart licensing mode, you can't revert. They should improve on the visibility of the smart licensing mode so that it can indeed be smart and easier to use for the license renewal every year. That is one challenge."
"The user interface could be updated."
"The area of license renewal should be improved. We normally renew our license every year."
"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 interface is dated. It has looked pretty much the same for 15 years or so. It would be helpful to be able to do everything from one spot. The centralized quarantine and reporting are completely separate from policy administration."
"The solution could be less expensive."
 

Pricing and Cost Advice

"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."
"The solution is expensive."
"Compared to Cisco's on-prem service, the cost is the same, but you don't have to pay for the hardware and you don't have to maintain the system, as far as upgrades and hardware failures are concerned. It is cheaper to operate on their cloud service than it is to operate with their on-prem service."
"It is a reasonably priced solution."
"I rate the product price as six on a scale of one to ten, where one means it is a very expensive tool."
"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."
"We were using Proofpoint and then we switched to Cisco... reportability was one of the main reasons we switched, but the biggest one was cost. If you can get an equivalent functionality for a better price it's wise to do so. That's what our primary decision came down to: We could get equivalent functionality at a lower price point."
"There were no other costs in addition to the standard licensing fees."
