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 tool's most valuable feature in preventing security breaches revolves around the area of malware protection that the product provides."
"The product blocks spam emails."
"Anti-Spam and Advanced Malware Protection are the most valuable features; they provide protection from most email threats and we also have the option to block Zero-day attacks."
"The technical support from Cisco is perfect."
"There were detailed logs available. That was a seriously good feature... It turns out these were actually spoof emails that came into our environment. I got to know about them from the log system."
"It blocks bulk marketing messages, graymail, spam, and provides advanced malware protection."
"The reasons I chose Cisco Secure Email Gateway are the interface is - it's easy to use - and the support is great."
"The solution is valuable if you are looking for a security email gateway that provides you with the most services possible."
"It is stable and reliable."
 

Cons

"The user interface needs massive improvement. While the device works fine and it's not complicated to write policies, renaming menu items and showing policy flow in conjunction with the application could help."
"I would like to see sandboxing for email, where suspicious emails received by the system are analyzed through online services."
"The user interface of the Email Security Gateway should be improved."
"The areas of Cisco Secure Email that could be improved or enhanced are the slowness in the console."
"That's why I wouldn't give it anywhere near a perfect score, because the artificial intelligence just isn't there yet."
"The solution needs to improve its advanced phishing filters. It is very good at filtering things which have bad reputations. However, when phishing or malicious emails are new or coming from a legitimate source, we don't feel that the solution is working."
"Having Cisco Email Security as a standalone solution is not good enough. It needs to be combined with another solution."
"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."
"The solution could be less expensive."
 

Pricing and Cost Advice

"It is an expensive product. I rate its pricing an eight or nine."
"It is expensive. I would rate it 2 out of 10, where 1 is the most expensive and 10 is the cheapest."
"The licensing was all transferred."
"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 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."
"There are additional fees for adding features."
"Pricing depends on your environment and which model you want to buy."
"The pricing for the Cisco Email Security Appliance involves recurring costs for licenses based on the contracted time frame, such as one year, three years, or five years. Renewals are required after the license expires."
