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.

Helps us reduce phishing email attacks and has a user-friendly dashboard
It is the best product. It helps reduce spam and phishing attacks. It has user-friendly Real-Time Phishing Mitigation features for environmental protection. It primarily focuses on verifying security features like SPS (Sender Policy Framework) and Smart DKIM (DomainKeys Identified Mail). The DLP feature ensures that only emails meeting the required security standards pass through the secure gateway. The configuration and management of the policies and settings are easy to navigate. I rate it an 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 features and functionalities are much better than Microsoft's in-built Defender plan."
"Cisco has a threat mechanism called cloud-based Talos, where all the threats are inbuilt."
"It has an efficient email filtering feature."
"It's very easy to deploy and configure."
"The solution is stable."
"I highly recommend it as one of the best choices."
"Regarding stability, Cisco Secure Email Threat Defense is very stable."
"Secure Email Threat Defense's scalability is good."
"It helps reduce spam and phishing attacks."
"The solution is easier to manage than FortiMail. You can implement policies easily."
 

Cons

"The product's complexity at times results in redundant rule sets that are difficult to untangle, highlighting the need for streamlined management systems and a more user-centric approach to system configuration."
"Cisco's multiple product lines and verticals made this just one of their many verticals, and we could see a shift in focus."
"From a technical point of view, Cisco is far behind in terms of cybersecurity, and it has to improve very much."
"Customers will benefit greatly from monthly billing because the majority of customers today use the cloud, be it Office 365, or Google Cloud."
"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."
"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."
"The search area has room for improvement. When you go to the next page, it remains at the bottom of the current page that you're on. Also, under the reports section, it allows you to see any "convictions," but if you want to search for those convictions you have to remember when they all came in and go back and edit the search accordingly. You cannot click on the list of convictions to actually see if you had a spike at a certain time."
"We encounter issues while searching for missing emails."
"Its pricing could be affordable."
"The solution does not always effectively identify zero day spam and phishing, but once reported the correction occurs very quickly."
 

Pricing and Cost Advice

"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."
"The feedback from vendors and customer is that it is expensive."
"It is expensive compared to other vendors."
"Email Security Gateway's pricing is good."
