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.

Cons

"I'll rate it higher when it can be easier to configure or connect to the cloud to report on the attachments."
"An additional feature that could be added is a pop-up screen notifying you that an email has been blocked, without having to double click on it to take you there it could provide you with a summary explaining why it was on hold or why was it spam when you hover over it with your cursor."
"ortiMail has some latency issues and sometimes takes time to receive emails."
"Maybe FortiMail's integration could be better."
"Fortinet FortiMail could improve general user management. There are no password policies for users."
"The sandboxing features are not well done in Fortinet FortiMail, making it an area of improvement."
"A room for improvement in Fortinet FortiMail is that it only has a hardware version. I also didn't find the solution scalable, so that's another area for improvement."
"High Availability needs improvement."
"The solution's pricing could be improved."
"The product's pricing could be more flexible."

Pricing and Cost Advice

"Price-wise, the solution is not far from Microsoft ATP. So, it is affordable."
"In the future I would like it if there's a possibility to lower the price of the bandwidth and UTM. It is quite expensive."
"This is a good solution and value for the money."
"The pricing is on the higher side."
"It is reasonable."
"I have no information on pricing for the competition because right now, my company is working only with Fortinet, but I can say that in general, the price for Fortinet FortiMail was accepted by the customers easily. The POC is also important when a customer is buying a solution. The customer wants to see how the product runs, and as Fortinet FortiMail is a stable product that runs without big issues, it has a bigger chance of getting chosen by customers over its competitors, even if its price may be a little higher. Pricing for the solution is competitive. Sometimes it's less, sometimes it's a little bit higher, but it isn't far from what other solutions charge."
"The annual cost is $55,000."
"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."
"I rate Trend Micro InterScan Messaging Security’s pricing a seven out of ten."
"Trend Micro is an expensive solution."
