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

"After three months of evaluating FortiMail, it has exceeded our expectations and we will definitely continue using it."
"The product helps users handle security challenges as it offers prefiltering options and does relatively good incident reporting."
"The solution is very reliable and very stable."
"It has a very high level of security through special licensing with solutions like FortiGuard, sandboxing solutions in the cloud, and URL rewriting solutions."
"The solution can scale."
"The product is easy to use, its performance is very good and it is stable, and the security is quite good overall."
"The solution has a user-friendly interface. It is easy to deploy and handle. You can easily troubleshoot the issues of the solution."
"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."
"The technical support services are excellent."
"The solution provides protection with its Email Track Records and Machine Manual features."
"With Trend Micro email security gateway, we can deploy features like DLP and BEC."
 

Cons

"Issues with the current email search functionality."
"I have faced issues from one of the customers that they received spam emails. I think they need to look into it and improve their signatures."
"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."
"The solution could improve by making the UI more user-friendly and increasing spam and threat detection capabilities."
"ortiMail has some latency issues and sometimes takes time to receive emails."
"I would like the integration to be easier."
"Sometimes it takes a little bit too long to determine if an email is good or not. If they could shorten that time span, it'd be so much better. It does delay our email, which does not make users happy. That said, I would have to say we have not been blacklisted for quite a while now."
"There have been instances when Fortinet FortiMail rejects valid emails because some of the service partners of the customer have not been configured accurately, so the system considered valid mails as attacks to be quarantined, so aside from improving the filters, there should also be an improvement in the categorization of emails in the server."
"The product's pricing could be more flexible."
"There is room for improvement in content filtration, expressions, file sharing, and policy configuration."
"The solution's pricing could be improved."

"There is a license required for this solution."
"It is a fairly priced product, considering what it does. The product offers good value for the money users spend on it."
