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.

Quotes from Members

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

Pros

"FortiMail Cloud is very fast."
"Fortinet's support is really good."
"Content disarming and analysis are essential features in our email security setup"
"Fortinet and other software ensure that my company's email remains safe, helping to avoid access issues at some cost in production."
"The most valuable feature is the advanced threat protection."
"It has the best feature for processed mail analysis."
"The implementation was very professional. There are a lot of features I can get through Fortinet and FortiMail, such as security. FortiGuard is the most reliable and professional mitigation center to handle incidents and risk that I have to face."
"The most valuable features are filtering and sandboxing."
"The feature I found most valuable was getting details on the emails, being alerted once those emails got a bad reputation, and then being able to take action on those emails."
 

Cons

"This solution is slow and it should be made faster."
"Fortinet policies add an extra load to the endpoint."
"I would like to see more advanced sandbox features, where you can actually download to a machine where you can test."
"There are no specific new features I would suggest at this moment."
"The setup of the rules can be improved. I think it should be simplified and would be the best improvement in the system."
"The price is relatively expensive."
"Email sorting is missing from this solution."
"Networking should be simplified."
"This solution needs to improve the area of GUI as well as dashboards because they are very poor in terms of the current email security solution."
 

Pricing and Cost Advice

"It's on a subscribed basis."
"You only have to purchase one license for multiple participants."
"When we're talking about pricing, other products have about the same price. That is normal."
"I rate the price of Fortinet FortiMail Cloud a five on a one to ten scale, where one is the low price, and ten is the high price. It is an averagely priced product."
"The price of this solution could be more competitive."
"The licensing is for three years. In the beginning, we did not pay monthly, it was paid once for three years."
"The product's price is reasonable."
"I see how manageable and flexible the licenses are."
