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

"IronPort really helped with the mail filtering and load balancing between the Exchange servers they had."
"The tool comes with AI features. It is good for clients who already use Cisco products due to integration."
"Introducing Cisco Secure Email Gateway systems was a set change for us and reduced the number of unwanted emails by a huge factor, a benefit that has continued from when we first got the devices until today."
"I can customize the configuration and policies."
"Apart from the improvement needed to the filters, it was all good."
"IronPort allows visibility into the problem and an easy way to pinpoint policy offenders."
"The most valuable feature is the different content filters we are using, such as DKIM."
"It is doing its work. It is doing what it was actually designed to do. It has ensured we don't have business email compromises, and it has also ensured that our brand Galaxy is unique all year round."
"It is stable and reliable."
 

Cons

"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."
"Having Cisco Email Security as a standalone solution is not good enough. It needs to be combined with another solution."
"The user interface of the Email Security Gateway should be improved."
"The solution does not have a strong outbound service. It should also integrate DLP."
"Many smaller businesses opt for more cost-effective solutions, such as Gmail or Hotmail accounts, instead of investing in Cisco Secure Email, given its higher cost."
"We didn't get any malware, but a few phishing emails, maybe one or two, slipped in."
"The Forged Email Detection feature needs improvement, particularly with domain. The sensors are not that good and the rules sets are unclear."
"The configuration UI should be made more intuitive. Currently, it takes a while to understand how to do the basic configurations."
"The solution could be less expensive."
 

Pricing and Cost Advice

"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."
"At times, we feel the pricing is a bit too high, but then, there is also room for discounts. We enjoy a lot of discounts, and that is why we are still with them. There are no costs in addition to the standard licensing fees."
"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."
"Cisco Secure Email is not expensive, and licensing costs are yearly."
"It is a super big router that costs a few hundred thousand dollars."
"Pricing depends on your environment and which model you want to buy."
"There were no other costs in addition to the standard licensing fees."
"It is not that costly. We pay for the solution through a contractor and pay an annual fee."
