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.

Stable, but malware needs improvement and customer support is poor
They need to improve the malware in the product. I am not satisfied with Clearswift because of the lack of customer support. The support is poor, the supplier takes a lot of time and it's expensive. We have some issues here when I contact the supplier, it takes a lot of time for them to get back to us but there's no solution. I am now looking at Symantec as a possible alternative.
