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 deployment is simple and once up and running it is easy to manage."
"Clean user interface and good sandbox."
"Fortinet utilizes specialized processing units, which network faster and sample more efficiently compared to others."
"One major benefit of the Fortinet FortiMail product is its ease of management."
"The number of false positives is minimal."
"We found the initial setup to be mostly straightforward."
"The most valuable feature of the solution is the tool's ability to prevent phishing attacks."
"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 Ui isn't that intuitive."
"Fortinet FortiMail's pricing could be improved."
"The biggest room for improvement would be the deployment. It will be hard for someone who doesn't understand the interface to deploy. If you understand it, you can find your way around the problems."
"ortiMail has some latency issues and sometimes takes time to receive emails."
"The product should work on licensing and provide more detail once the license is selected for the customer."
"It can be easier to configure or connect to the cloud to report on the attachments."
"The solution could be improved by providing a virtual machine facility with a complete set of options in the VM setup."
"The statistics and BI in general could be improved."
"Malware needs improvement."
"FTP server and TRUST Manager functionality."
 

Pricing and Cost Advice

"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."
"It's not as that expensive with the competitive different brands. The products sell a lot."
"Pricing is straight-forward and renewable without complicated pricing structures."
"Pricing is based on initial license purchase and use volume."
"It is reasonable."
"My company has a three-year license for Fortinet FortiMail, including the support, but I'm not so sure of how much the solution costs because I'm not part of the procurement team. What's more important to me is the functionality and stability of Fortinet FortiMail. In terms of Fortinet FortiMail licensing, the cost is calculated based on company requirements. For example, it's based on the features you need for your environment, on capacity, how many CPUs you have, etc."
"The solution is reasonably priced compared to one of its competitors."
"The solution is quite pricey compared to other competitors in the market."
