Featured Reviews

Abhimanyu Das - PeerSpot reviewer
Senior Associate at a tech vendor with 10,001+ employees
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.
AsadAli - PeerSpot reviewer
SOC Team Lead at a security firm with 51-200 employees
Centralized protection has transformed email security and incident investigations by reducing false positives and improving behavioral threat detection
The challenges include the challenge of finalizing a product that has all the security features or capabilities that are usually required. For example, if there is an EDR platform that's just monitoring IDS signatures, it won't be as beneficial as one with behavioral monitoring and other critical aspects required according to the best practices of the industry. Additionally, if there is a product that can provide a centralized view Trend Vision One does, it really grabs the customer's interest because customers usually don't have to buy separate EDR, XDR, or SIEM solutions or a console for their SOC analyst or email security team. These challenges consist of managing multiple teams and products. Trend Micro Email Security comes in and solves these problems.Trend Micro Email Security is generally a bit more difficult to implement compared to the rest of the solutions such as network security modules or EDR modules, which are much easier. Trend Micro Email Security has some complexities in implementation, but there aren't any significant shortcomings that require Trend Micro to improve.
