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 filtering is definitely better at catching both spam and malicious messages, and there's a lot of extremely granular ability for setting up rules. You can do it the way you want to. The Microsoft solution tends to be pretty limited in how it allows some of that to be done."
"The most valuable features are protection against ransomware and spam."
"It sends us reports, where we can see if there have been attacks, e.g. DDoS. If so, we can switch to a clean IP."
"The most valuable feature is the different content filters we are using, such as DKIM."
"I love the Advanced Malware Protection feature. It works very well... The appliance has more security such as SDF, DKIM, DMARC, and encryption."
"Spam controls are excellent because they are a powerful feature that operates almost effortlessly."
"The reasons I chose Cisco Secure Email Gateway are the interface is - it's easy to use - and the support is great."
"Cisco's Secure Email integrates with Cisco Firewalls, utilizing the AMP as their anti-malware engine, which allows for information sharing between devices."
"It is stable and reliable."
 

Cons

"The configuration UI should be made more intuitive. Currently, it takes a while to understand how to do the basic configurations."
"The area of license renewal should be improved. We normally renew our license every year."
"There could be additional DLP functionality for it."
"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."
"The pricing needs to be reconsidered or enhanced."
"I would rate the stability a six out of ten. We had multiple issues with the stability."
"If you are not a technical guy, it is hard to maneuver, but as soon as you work on it, it gets better and better. If there was a better way to know how to do things or how to find things, it would be good."
"The scalability must be improved."
"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."
"Cisco Secure Email and the support are priced well. It's not cheap, but there are other solutions that offer less and cost so much. For example, Microsoft is more expensive than Cisco."
"There are additional fees for adding features."
"It is expensive. I would rate it 2 out of 10, where 1 is the most expensive and 10 is the cheapest."
"It is an expensive product. I rate its pricing an eight or nine."
"It is a super big router that costs a few hundred thousand dollars."
"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 licensing was all transferred."
