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

"They have a feature called CDR, Content Disarm, Reconstruction, click protection, and DLP for encryption purposes."
"FortiMail effectively filters all emails coming to our mail server, blocking malicious ones automatically."
"Fortinet’s support services are good."
"The solution has a user-friendly interface. It is easy to deploy and handle. You can easily troubleshoot the issues of the solution."
"Fortinet FortiMail's most valuable features are antispam, antivirus, database, and data loss prevention (DLP)."
"This solution is good for small and medium enterprise companies."
"The solution is very, very stable."
"Fortinet FortiMail's most valuable features are its performance and security."
"With Trend Micro email security gateway, we can deploy features like DLP and BEC."
"The solution provides protection with its Email Track Records and Machine Manual features."
"The technical support services are excellent."
 

Cons

"Fortinet FortiMail could improve general user management. There are no password policies for users."
"There are features that other solutions have that this one is lacking, such as reporting options. I hope in future releases they advance their features list."
"Maybe FortiMail's integration could be better."
"The product could incorporate even more artificial intelligence to enhance the functionality, but it is a competetive and intelligent product as it."
"Sometimes, authentic emails get blocked by the solution's firewall."
"Improving the upgrade process, making it more user-friendly, and simplifying the management of hardware components could enhance the overall user experience and appeal of Fortinet's email security solution."
"I think the security of the product could improve."
"The security products stop their operations once the subscription period expires. It is a wrong policy. If I trust a product, it has to continue working even after expiry. It should have a grace period of 30, 40, or 60 days. We can extend the subscription during those days. In some places, subscription extensions can take up to six weeks. During the renewal process, the support offered by the company is very poor. It also reduces security. We pay for the expired period but do not get protection during those times. The user of Fortinet FortiMail should have a feature to see spam names."
"There is room for improvement in content filtration, expressions, file sharing, and policy configuration."
"The solution's pricing could be improved."
"The product's pricing could be more flexible."
 

Pricing and Cost Advice

"The pricing is good."
"It is an expensive product."

"Fortinet FortiMail is a little bit expensive."
"Trend Micro is an expensive solution."
"I rate Trend Micro InterScan Messaging Security’s pricing a seven out of ten."
