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

"We are now protected against spam emails."
"Cisco's Secure Email integrates with Cisco Firewalls, utilizing the AMP as their anti-malware engine, which allows for information sharing between devices."
"For what you get for the product, the support, and the overall stability, it is definitely a good return on investment."
"You are never secure without some solution from Cisco."
"Overall, it is a very good product, and I'm very happy with it."
"The product's initial setup phase was easy."
"The system enables end users to manage their own whitelists/blacklists."
"Email service is one of the services that we offer at Galaxy, and Cisco ESA has improved our business so much that our customers want to maintain their business with us for email security, with over 500 domains on our email platform and improved profitability in everything."
"It is stable and reliable."
 

Cons

"The product's GUI for the dashboard needs improvement."
"The discontinuation of physical hardware solutions is a significant area for improvement in Cisco Email Security Appliance. This decision has posed challenges as virtual appliances are now the only option, which may not be suitable for all industries. The uncertainty regarding the future of the hardware aspect of the solution is a notable concern."
"The initial setup was complex because I have two sites with physical clusters."
"Having Cisco Email Security as a standalone solution is not good enough. It needs to be combined with another solution."
"We didn't get any malware, but a few phishing emails, maybe one or two, slipped in."
"The pricing needs to be reconsidered or enhanced."
"They could improve the filters. In my time at the company, there were several times we had to contact support to update the filters."
"That's why I wouldn't give it anywhere near a perfect score, because the artificial intelligence just isn't there yet."
"The solution could be less expensive."
 

Pricing and Cost Advice

"It is not that costly. We pay for the solution through a contractor and pay an annual fee."
"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."
"There were no other costs in addition to the standard licensing fees."
"As per market availability, this solution is more expensive than other vendors."
"The price is significantly high."
"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 expensive, but we get what we pay for."
