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 most valuable features are Advanced Malware Protection, URL filtering, and of course Reputation Filtering."
"This solution provides some benefits, like comfortable access to TAC support. You get prompt support when working directly with Cisco."
"There are a lot of filters for scam emails and things like that work out of the box. You can also use the antivirus features. I like its features."
"The logs are easily readable and help diagnose problems, although they can be difficult to find initially. The solution addresses our email security, but for the rest of our security, we would use multiple vendors. It covers everything through email, like antivirus, IDS, and IPS."
"Capital expenditure is a significant consideration, and the impact on major expenditures prompts a careful analysis before onboarding the new product."
"The solution works well."
"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."
"Cisco Secure Email has strong inbound services."
"It is stable and reliable."
 

Cons

"We have been struggling in the last month with Cisco encryption and with the S/MIME encryption. I don't know if it is an issue on our side or if these features of the solution are not working very well."
"I use the search all the time. Sometimes, it is hard to search for things and things are hard to find. People come to me all the time, saying, "This email didn't get through." Then, I go searching and don't find it on the first search. You have to think about alternative searches. I don't know if there is an easier way that they could help to find things. I don't know how they could simplify it, because now everybody else is using the cloud and everything is coming from Office 365, or whatever. It is just not the same environment from years ago where everybody had their own server and you could search easier."
"The product's GUI for the dashboard needs improvement."
"The UI is definitely one area of improvement because it doesn't match other interfaces and the navigation can be a little clunky."
"The interface is dated. It has looked pretty much the same for 15 years or so. It would be helpful to be able to do everything from one spot. The centralized quarantine and reporting are completely separate from policy administration."
"The Forged Email Detection feature needs improvement, particularly with domain. The sensors are not that good and the rules sets are unclear."
"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."
"I would like to see features like AI since it is currently an area that the product lacks."
"The solution could be less expensive."
 

Pricing and Cost Advice

"The product's price falls on the higher side when compared to the other products on the market."
"I don't have the insights into it, but compared to different products, it seems to have a medium level of pricing."
"As per market availability, this solution is more expensive than other vendors."
"There were no other 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."
"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."
"Licensing costs depend on how many users there are. It could range between $5 and $7 per month, per user."
"We do annual licensing for Cisco Secure Email Gatewayand SMA together, and possibly SmartNet support. Packaged together, the cost is just under $38,000."
