Featured Reviews

Pravin Mandlik - PeerSpot reviewer
Provides enhanced email security with potential agent compatibility issues
There are definitely features that Fortinet should work on. I'm not the right person to implement those features. For a portable cloud solution, a customer has more affinity towards a solution where endpoint security is already in place. In endpoint security, they are not at the latest quadrant. That is why a customer with existing endpoint security solutions like Trend Micro might prefer a main security solution from that vendor. If we go for FortiMail Cloud and have a separate endpoint security solution, there are two agents that have to sit on a customer endpoint. From that perspective, Fortinet policies add an extra load to the endpoint. Maybe other solutions have an advantage when it comes to Fortinet.
ShaheenKapery - PeerSpot reviewer
Provides valuable security features and has a straightforward setup process
The initial setup process is straightforward and takes a weekend at most. A .com domain can take up to forty-eight hours, while a local domain takes about four to eight hours because it has to propagate through the international DNS records. It is a cloud-only solution. If you're managing email security on-premises, you use your bandwidth to download emails, including spam, and then use your servers to clean it up. For example, say a third of your email is spam; this consumes significant bandwidth and resources. However, if you use Mimecast, they filter the emails on their servers before delivering them to you. It can be a major selling point in regions with expensive bandwidth, such as Africa. You can save bandwidth and improve overall efficiency by offloading the spam filtering to Mimecast.

"The deployment is simple."
"Fortinet's support is really good."
"Fortinet and other software ensure that my company's email remains safe, helping to avoid access issues at some cost in production."
"It has the best feature for processed mail analysis."
"I am impressed with the tool's ability to setup rules and destinations. It also helps to monitor suspicious items."

Cons

"The price is relatively expensive."
"FortiMail needs to develop further, particularly in integrating AI features, to keep up with rapidly advancing technology."
"There are no specific new features I would suggest at this moment."
"This solution is slow and it should be made faster."
"The downside of this solution is that it is difficult to implement policies on FortiMail."

"This ease of use and user-friendliness is something we believe could be improved in FortiMail."
"I can't see the feedback to the FortiMail gateway."

"As a user, the user interface of the management console could be upgraded, for example."
