Helps prevent security breaches but fails to improve in the area of AI
I have not noticed any impressive advanced threat protection mechanisms in the tool. I don't know if there are any AI features in the product. I don't know if there is any other technology embedded in the solution. Cisco Secure Email successfully mitigated potential email threats. My company has seen plenty of scenarios where Cisco Secure Email successfully mitigated potential email threats, spam emails, and fraudulent domains. The product is good for dealing with spam emails, and it can take care of more than 100 spam emails per day. A huge number of spam emails are monitored with the help of Cisco Secure Email. I would not recommend the product to other businesses because you need to have some kind of expertise in configuring and knowing a bit about the tool's GUI. The tool also lacks in the area of AI mechanics. If I would like to have an overview and review another solution, I would go for another product other than Cisco Secure Email. I can definitely suggest others to look at the product and review it, but I would also recommend that they compare it with the other solutions in the market. I wouldn't prioritize Cisco Secure Email over other tools. Either the support partner of the product or I take care of the tool's maintenance phase by looking into the configurations and doing some fine-tuning. I rate the tool a seven to eight out of ten.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The tech engineers are very knowledgeable."
"What I find the most valuable about Cisco Secure Email is that the logs are not that difficult to see even if you're not used to them. The logs are reasonably readable and diagnosing the problem is not too hard with them."
"Anti-Spam and Advanced Malware Protection are the most valuable features... and we also have the option to block Zero-day attacks."
"Cisco's Secure Email integrates with Cisco Firewalls, utilizing the AMP as their anti-malware engine, which allows for information sharing between devices."
"Spam controls are excellent because they are a powerful feature that operates almost effortlessly."
"Administration of the email domains and custom filters are easily done via the web interface."
"The security features are valuable."
"We rely heavily on antivirus protection, email content filtering, and authentication mechanisms to ensure compliance with email security. Regarding phishing attempts, while phishing protection features are crucial, we also emphasize user education as a critical defence. The intelligence services Cisco provides, such as the Cisco Intelligence Center, play a significant role in analyzing and validating threats, including phishing attempts, in our email security practices."
"It is stable and reliable."
 

Cons

"In some cases, detection is missed, leading to false positives where genuine emails are flagged as spam."
"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."
"We would like to see more options for the customization of content filters."
"The graphical user interface is not user-friendly like other vendors. I find it very difficult at times to find some options on the UI."
"Scalability has certain shortcomings and needs to be improved because there are service providers who provide better scalability.v"
"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."
"We have Microsoft and we have the E5 licenses, they have more EDR responses on certain emails. That's something that Cisco ESA on the cloud doesn't have. They don't do anything about MITRE attacks. They only detect if there is a malicious email or a threat and they remove it."
"The primary areas for improvement are the pricing and the complexity of deployment."
"The solution could be less expensive."
 

Pricing and Cost Advice

"There were no other costs in addition to the standard licensing fees."
"It's adapted to the market. It's similar to other vendors. We at least don't have many problems regarding that because Cisco is adaptable on that side. When we present the solutions to the customers, we tend to achieve the goals that the customer has in terms of the budget for such implementations."
"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."
"It is a super big router that costs a few hundred thousand dollars."
"Licensing costs depend on how many users there are. It could range between $5 and $7 per month, per user."
"It is not that costly. We pay for the solution through a contractor and pay an annual fee."
"In addition to the standard licensing, there is a cost for SMARTnet as well."
"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."
