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.

Targeted email filtering has reduced spam and phishing and now saves significant investigation time
The best features of Fortinet FortiMail include its techniques and tactics, which are highly effective compared to other solutions such as Microsoft 365. Although Fortinet FortiMail may not be as advanced in some aspects, it is well recognized for its strong performance in handling spam and phishing. It performs thorough mail scanning and also offers a sandboxing feature that enhances protection. Fortinet FortiMail has had a positive impact on my organization by significantly reducing unwanted email activities such as spam and phishing. It provides accurate detection and generates results that often exceed what can be achieved through manual analysis. Since deploying Fortinet FortiMail, I have observed a reduction in investigation time by at least 20 to 30 percent.

Quotes from Members

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

Pros

"Cisco has a threat mechanism called cloud-based Talos, where all the threats are inbuilt."
"Regarding stability, Cisco Secure Email Threat Defense is very stable."
"The advanced threat analytics and URL filtering in threat detection are good features that are working well."
"Cisco Secure Email Cloud Mailbox can handle a complete portfolio, which is required to protect any kind of attack coming from emails. However, it does not have advanced phishing, but it is available through Cisco. If you compare Cisco Secure Email Cloud Mailbox with the competition, in the competition you have to have one or two solutions together to address the customer's requirement, whereas Cisco Secure Email Cloud Mailbox is addressing everything, such as web domain and email protection. If there is any kind of challenge it will come across through email."
"I highly recommend it as one of the best choices."
"This solution is easy to use."
"The product offers protection, email security, anti-spam, and antivirus."
"The features and functionalities are much better than Microsoft's in-built Defender plan."
"Technical support is great. They're available 24/7 and their response time is typically within the hour."
"The solution is very reliable and very stable."
"The most valuable features of this solution are anti-spam, sender reputation, and antivirus."
"It is one of the most efficient solutions in our environment. We have more than nine hundred users. All of these users are protected by Fortinet FortiMail."
"It actually filters the compromised emails when on a network layer itself."
"The most valuable feature of the solution is its interface, allowing users to get around the solution easily. The integration capabilities in the solution are also very easy."
"The solution has a user-friendly interface. It is easy to deploy and handle. You can easily troubleshoot the issues of the solution."
"FortiMail effectively filters all emails coming to our mail server, blocking malicious ones automatically."
 

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."
"The pricing could always be better."
"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."
"Customers will benefit greatly from monthly billing because the majority of customers today use the cloud, be it Office 365, or Google Cloud."
"From a technical point of view, Cisco is far behind in terms of cybersecurity, and it has to improve very much."
"The tool gives false positives and it needs to be more accurate. I would like to see AI as a new feature."
"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."
"The solution is a bit expensive."
"I think the security of the product could improve."
"Sometimes, the tool flags legitimate incoming traffic as spam."
"I need a stable update in the product that stays for a long time instead of having to deal with frequent updates."
"I think they need to look into it and improve their signatures. This will help with blocking incoming spam emails."
"Fortinet FortiMail can be improved in terms of its dashboard, which is small and not visually appealing, making deeper investigations difficult."
"The product should work on licensing and provide more detail once the license is selected for the customer."
"The solution lacks to provide more visibility when there is a problem, and it needs to be tracked."
"Fortinet FortiMail is considered overpriced by Indian rupee standards. My organization is not profit-making, and academic pricing is required, but it may not be available for security products like FortiGate."
 

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 feedback from vendors and customer is that it is expensive."
"It is expensive compared to other vendors."
"The solution’s pricing is manageable."
"It is reasonable."
"Fortinet FortiMail is a little bit expensive."
"The pricing is on the higher side."
"Pricing is based on initial license purchase and use volume."
"It's not as that expensive with the competitive different brands. The products sell a lot."
"It is a fairly priced product, considering what it does. The product offers good value for the money users spend on it."
"Fortinet Fortimail has reasonable pricing."
"We paid approximately $30,000 for the solution. It is less expensive than some other solutions. We have one license that carries all the features that we wanted."
