Provides robust email security features but requires improved modernization and complexity management
Modernization is an area that could be improved for Cisco Secure Email Threat Defense, as some features have lagged behind newer competitors, potentially offering more advanced analysis capabilities. The initial setup is not straightforward and requires expertise and time to master configurations such as spoofing and DLP. More control over backend functionalities and simplifying rule management could enhance user experience. 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. Furthermore, the pricing might deter new users who could opt for alternative, more cost-effective solutions.

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

"The advanced threat analytics and URL filtering in threat detection are good features that are working well."
"On ease of use, it rates very high."
"Overall, it's certainly a very good idea to integrate another layer on top of Microsoft Advanced Threat Protection."
"I would say it's very comprehensive, with multiple antivirus OEMs, virus encrypt features, encryption, and more."
"It has an efficient email filtering feature."
"The solution is stable."
"This solution is easy to use."
"The features and functionalities are much better than Microsoft's in-built Defender plan, and this product has helped us to protect our organization from any malware attack in the past."
"This solution is good for small and medium enterprise companies."
"FortiMail is an awesome product mechanically."
"The most valuable feature of the solution is the tool's ability to prevent phishing attacks."
"The key benefits of this solution are its user-friendly interface and clear instructions, as well as the wealth of online resources and helpful health community available for support. These features make it easy for users to navigate and utilize the solution effectively."
"Technical support is very good."
"The most valuable feature of Fortinet FortiMail is its fully detailed dashboard."
"The Fabric aspect of the solution is excellent, with more accuracy in the classification, and all the other functions and features on FortiMail are great; I love them all."
"The GUI isn't hard to use. When we do a demo and explain the features of Fortinet products to our customers, they understand very quickly. They can easily manage their systems without us."
 

Cons

"The physical appliance has been discontinued, although the platform still exists."
"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."
"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 search area has room for improvement."
"Cisco's multiple product lines and verticals made this just one of their many verticals, and we could see a shift in focus."
"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."
"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."
"It would be nice if we could manage the solution from the cloud so I could handle things off-site if necessary."
"The solution is user-friendly to a degree but the dashboard needs improvement."
"I need a stable update in the product that stays for a long time instead of having to deal with frequent updates."
"Issues with the current email search functionality."
"Improving the upgrade process, making it more user-friendly, and simplifying the management of hardware components could enhance the overall user experience and appeal of Fortinet's email security solution."
"They should add a lot of threat-intelligence feeds from different sources - not only from one source (FortiGuard)."
"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."
 

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."
"I find Fortinet FortiMail pricing reasonable. There's no additional cost apart from its standard licensing fees."
"The product's licensing part depends on the number of mailboxes and the hard disk needed by customers. The cost of the license depends on the number of mailboxes and the number of emails."
"FortiMail is not cheap."
"Pricing is straight-forward and renewable without complicated pricing structures."
"The tool is very expensive."
"In terms of licensing, we are using a virtual machine license for the single virtual server which it runs on. Doing it this way enables us to cut costs by only licensing FortiMail for our exact use case. If you need to expand in future, you can later buy extra licenses per virtual machine."
"There is either an annual or six-month charge to use this solution. Fortinet FortiMail is cheaper than Proofpoint or Cisco Security, or other email security appliances."
"Fortinet FortiMail is a little bit expensive."
