Threat intelligence with fast attack detection enables comprehensive email protection
In some cases, detection is missed, leading to false positives where genuine emails are flagged as spam. This could result in users not opening genuine emails. We have highlighted this to Cisco because sometimes phishing or marketing campaigns, which are genuine, are incorrectly flagged as spam. The solution should better analyze the actual content rather than only focusing on the email header or origin.

Clawback feature performs well but analytics and integration capabilities need improvement
The integration capability with other threat intelligence platforms is not optimal, as I have experienced difficulty in sending logs to our SIEM. Cisco Secure Email Threat Defense's flexibility could be enhanced while it mostly integrates with cloud solutions, but not on-premise. The behavioral analysis capability of Cisco Secure Email Threat Defense is not particularly helpful for identifying new, evolving threats within my company, as it keeps flagging legitimate emails as malicious. Regarding room for improvement, the significant number of false positives should be addressed. The solution does not adapt to behavioral analytics and does not make changes when it sees a pattern.

Quotes from Members

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

Pros

"The advanced phishing protection and the integration with the awareness tool that Cisco has embedded into the solution to bring awareness to the customers about the dangers of phishing attacks and other things that come from email are the most valuable features."
"The tool's most valuable feature in preventing security breaches revolves around the area of malware protection that the product provides."
"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."
"It is a user-friendly product."
"Because we scan products, and there is a lot of critical data, security is very important in these cases."
"The technical support from Cisco is perfect."
"Users were able to do a check by themselves on quarantined emails. They could check if a valid email had been stopped, if it matched up with the SPF certification."
"The strong point of the solution is that we hardly get any spam emails because of Cisco Secure Email."
"Cisco Secure Email Threat Defense's best features include user management of graymail, enhancing security awareness by allowing users to manage cold calls, sales-based items, and ensuring email compliance."
"I would say it's very comprehensive, with multiple antivirus OEMs, virus encrypt features, encryption, and more."
"It's very easy to deploy and configure."
"Regarding stability, Cisco Secure Email Threat Defense is very stable."
"The product offers protection, email security, anti-spam, and antivirus."
"Secure Email Threat Defense's scalability is good."
"The advanced threat analytics and URL filtering in threat detection are good features that are working well."
"I highly recommend it as one of the best choices."
 

Cons

"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."
"Licensing is quite complicated for a number of customers, including ourselves."
"The product's GUI for the dashboard needs improvement."
"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."
"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."
"The UI is definitely one area of improvement because it doesn't match other interfaces and the navigation can be a little clunky."
"The reporting functionality needs to be improved."
"In future releases, I would like to see two main improvements come to mind. First, the current solution requires maintaining two separate operating systems for FTD, which can be cumbersome. I'd love to see a single operating system for the FTD box."
"We encounter issues while searching for missing emails."
"Customers will benefit greatly from monthly billing because the majority of customers today use the cloud, be it Office 365, or Google Cloud."
"Cisco Secure Email Cloud Mailbox can improve by adding advanced phishing, then the solution would become the best in the market. However, this could increase the price even more. Additionally, if CES with domain protection could be added it would be an even better solution."
"This solution could be improved by integration with Sandbox."
"The learning curve shows that in the beginning, there are numerous false positives. For one month, we had to reclassify the false positives manually until the system learned."
"There is still room for improvement in terms of integrations with other Cisco tools and non-Cisco tools. There is also some room for improvement needed in terms of the reporting."
"From a technical point of view, Cisco is far behind in terms of cybersecurity, and it has to improve very much."
"The behavioral analysis capability of Cisco Secure Email Threat Defense is not particularly helpful for identifying new, evolving threats within my company, as it keeps flagging legitimate emails as malicious."
 

Pricing and Cost Advice

"I would rate the pricing a ten out of ten, where one is cheap, and ten is expensive."
"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."
"In addition to the standard licensing, there is a cost for SMARTnet as well."
"It is expensive. I would rate it 2 out of 10, where 1 is the most expensive and 10 is the cheapest."
"We were using Proofpoint and then we switched to Cisco... reportability was one of the main reasons we switched, but the biggest one was cost. If you can get an equivalent functionality for a better price it's wise to do so. That's what our primary decision came down to: We could get equivalent functionality at a lower price point."
"There are additional fees for adding features."
"It is a reasonably priced solution."
"You're going to get what you pay for. If you're not willing to pay the price of Cisco, you're not going to get a product that's as good as Cisco. I don't think Cisco is overpriced, because for the last two years I've been comparing it to Microsoft and Cisco has been cheaper and given us more features."
"The feedback from vendors and customer is that it is expensive."
"It is expensive compared to other vendors."
"Cisco Secure Email Cloud Mailbox does not have any competition with Sophos, Trend Micro, or other vendors of the world. However, there is a pricing premium for the solution. One has to look at it from that angle that while they are buying Cisco, there will be a premium, and Cisco justifies that premium value. That's why they're charging a high price."
"The solution’s pricing is manageable."
