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 most valuable feature of Fortinet FortiMail is its fully detailed dashboard."
"Its performance is very good and it is stable."
"FortiMail effectively filters all emails coming to our mail server, blocking malicious ones automatically."
"The solution is very, very stable."
"This solution is good for small and medium enterprise companies."
"The GUI isn't hard to use. When we do a demo and explain the features of Fortinet products to our customers, they understand very quickly. They can easily manage their systems without us."
"We found the initial setup to be mostly straightforward."
"Its threat detection capabilities have been beneficial."
"Ability to create your own content-filtering policies with relative ease."
"A stable solution."
 

Cons

"The sandboxing features are not well done in Fortinet FortiMail, making it an area of improvement."
"The support could be faster because we've been receiving complaints from customers, they say that when they raise a ticket, it doesn't take 24 hours to respond, sometimes the support responds after three days. This is a lot of time."
"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."
"I would like the integration to be easier."
"The web console management interface could be improved."
"It can be easier to configure or connect to the cloud to report on the attachments."
"In the Latin America market, some spam messages use Portuguese language. Some clearly spam messages would be better identified by the anti-spam if not for the language."
"They should add a lot of threat-intelligence feeds from different sources - not only from one source (FortiGuard)."
"FTP server and TRUST Manager functionality."
"Malware needs improvement."
 

Pricing and Cost Advice

"If you don't need the full bundle that includes everything, you have options for the small or medium enterprise environments."
"There is a license required for this solution."
"You need to pay additional fees for premium support."
"The pricing is on the higher side."
"It is a fairly priced product, considering what it does. The product offers good value for the money users spend on it."
"The solution is quite pricey compared to other competitors in the market."
"This is a good solution and value for the money."
"Price-wise, you get what you pay for in Fortinet FortiMail. Apart from the licensing costs, no additional expenses are attached to the solution's pricing."
