Senior Cybersecurity Engineer at a financial services firm with 11-50 employees
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

"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."
"Cisco Cloud Mailbox is used for copying emails, anti-spamming, and securing the company's email, and we really enjoy the anti-spamming capabilities as well as the rejecting of bulk emails, which we can customize by adjusting the variables, and it is very user-friendly."
"Secure Email Threat Defense's scalability is good."
"It has an efficient email filtering feature."
"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."
"Cisco has a threat mechanism called cloud-based Talos, where all the threats are inbuilt."
"The advanced threat analytics and URL filtering in threat detection are good features that are working well."
"At the end of the day, they look at the performance and the price, and Fortinet covers all the bases."
"The stability and performance of the solution have been great, and we have not had any problems since we have been using it."
"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 has a very high level of security through special licensing with solutions like FortiGuard, sandboxing solutions in the cloud, and URL rewriting solutions."
"Troubleshooting is very simple because you can see where the email was not delivered and why it would be considered as spam."
"FortiMail is extremely flexible and very easy to learn. Compared to other email security products that we've tried, it is mainly the ease of configuration that makes FortiMail valuable to us."
"We're happy with things."
"For now, as per our experience with FortiMail in handling a large number of emails and spams as well, in the past three years, we have been protected and saved from any attacks from the outside."
 

Cons

"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."
"We encounter issues while searching for missing emails."
"The tool gives false positives and it needs to be more accurate. I would like to see AI as a new feature."
"The physical appliance has been discontinued, although the platform still exists."
"The pricing could always be better."
"From a technical point of view, Cisco is far behind in terms of cybersecurity, and it has to improve very much."
"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 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."
"My customers frequently ask to have detailed documentation for FortiMail and FortiWeb as they have in FortiGate. What they currently have is not enough."
"The solution doesn't scale easily."
"High Availability needs improvement."
"I believe there is room for enhancement in content and web security features."
"Sometimes, authentic emails get blocked by the solution's firewall."
"Sometimes, the tool flags legitimate incoming traffic as spam."
"The dashboard is small, it doesn't have a huge dashboard that you can rely on, you need another application to work with it, which is why they created FortiAnalyzer."
"The logging information is sometimes not clear or easy to understand."
 

Pricing and Cost Advice

"It is expensive compared to other vendors."
"The solution’s pricing is manageable."
"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."
"Pricing is based on initial license purchase and use volume."
"There is a license required for this solution."
"FortiMail is not cheap."
"It is reasonable."
"If you don't need the full bundle that includes everything, you have options for the small or medium enterprise environments."
"FortiMail has extra charges for installation, configuration, and project management."
"The tool is very expensive."
"The pricing is on the higher side."
