MOHAN SUKUMAR - PeerSpot reviewer
Secure email management improves through advanced filtering and dynamic virus scanning
Fortinet FortiMail offers capabilities like settings for mail delivery, mail filtering, spam controls, and email bursting prevention. It also allows for email forwarding, dynamic filtering, and scanning based on virus signatures. I can set varying levels of security. The tool is flexible and provides essential features for mail security and management.
PC
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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The product's initial setup phase was very easy."
"Technical support is great. They're available 24/7 and their response time is typically within the hour."
"The most valuable aspects of this solution are that it protects us from spam and phishing attacks. We had a lot of attacks coming in and then we deployed this solution and they stopped. We no longer have any spam or phishing issues."
"When combining this solution with other Fortinet products, such as FortiGate, it integrates well and provides a comprehensive protection package."
"Fortinet FortiMail has a lot of valuable features. It works great. It also has an antivirus feature. Support for Fortinet FortiMail was also great when my team wanted to block some geographic IPs, but couldn't figure out how to do it. The support team provided clear communication on how to resolve that issue. Another valuable feature of Fortinet FortiMail is SPAM filtering which tells you how many spammy emails you've received. Based on my current use cases, I'm happy with Fortinet FortiMail."
"They have a feature called CDR, Content Disarm, Reconstruction, click protection, and DLP for encryption purposes."
"A full-featured email gateway solution that contains security threats reliably."
"I am satisfied with both the scalability and the stability of this solution."
"A stable solution."
"Ability to create your own content-filtering policies with relative ease."
 

Cons

"The tool needs to improve its pricing policy. Also, it needs to be more user-friendly. I would want it to improve email security as well."
"I need a stable update in the product that stays for a long time instead of having to deal with frequent updates."
"The logging information is sometimes not clear or easy to understand."
"The Ui isn't that intuitive."
"The solution's pricing is flexible and can be adjusted for African utility companies. Microsoft often offers special pricing formulas for African governments and organizations and it is similar to Fortinet FortiMail. In my country, government institutions receive discounted pricing from Fortinet FortiMail."
"The solution could be improved by providing a virtual machine facility with a complete set of options in the VM setup."
"The solution is user-friendly to a degree but the dashboard needs improvement."
"The product should work on licensing and provide more detail once the license is selected for the customer."
"Malware needs improvement."
"FTP server and TRUST Manager functionality."
 

Pricing and Cost Advice

"The product's licensing part depends on the number of mailboxes and the hard disk needed by customers. The cost of the license depends on the number of mailboxes and the number of emails."
"The price is acceptable for the support license it includes."
"This is a good solution and value for the money."
"We paid approximately $30,000 for the solution. It is less expensive than some other solutions. We have one license that carries all the features that we wanted."
"The pricing is on the higher side."
"The fees for Fortinet FortiMail can be complicated. However, overall the pricing is fair."
"FortiMail has extra charges for installation, configuration, and project management."
"The solution is quite pricey compared to other competitors in the market."
