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 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."
"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..."
"The system enables end users to manage their own whitelists/blacklists."
"The tool comes with AI features. It is good for clients who already use Cisco products due to integration."
"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."
"There is a huge return compared to if we didn't have a gateway appliance, as far as blocking malicious emails."
"The reasons I chose Cisco Secure Email Gateway are the interface is - it's easy to use - and the support is great."
"The added value of it is that every migration to a new version is initiated by the Cisco version itself, so that is a bunch of work that you don't have to do on the Cisco ESA system on-premise. As it becomes a safe platform, you don't need to invest anything in your own data center or in your upgrade path."
"It is stable and reliable."
 

Cons

"We cannot manage multiple devices from a single UI."
"The pricing needs to be reconsidered or enhanced."
"The primary areas for improvement are the pricing and the complexity of deployment."
"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 product's GUI for the dashboard needs improvement."
"Licensing is quite complicated for a number of customers, including ourselves."
"I would like them to add some clustering or high availability features."
"The UI is definitely one area of improvement because it doesn't match other interfaces and the navigation can be a little clunky."
"The solution could be less expensive."
 

Pricing and Cost Advice

"The licensing was all transferred."
"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."
"Licensing costs depend on how many users there are. It could range between $5 and $7 per month, per user."
"I would rate the pricing a ten out of ten, where one is cheap, and ten is expensive."
"It is a super big router that costs a few hundred thousand dollars."
"I don't have the insights into it, but compared to different products, it seems to have a medium level of pricing."
"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 are additional fees for adding features."
