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

"Clean user interface and good sandbox."
"The anti-spam functionality is good and works well."
"The solution has a user-friendly interface. It is easy to deploy and handle. You can easily troubleshoot the issues of the solution."
"The number of false positives is minimal."
"The important feature is the application control, which makes administration much easier. It also has an intrusion prevention feature. There's also the wireless functionality, which works well with Huawei devices."
"FortiMail is extremely flexible and very easy to learn. Compared to other email security products that we've tried, it is mainly the ease of configuration that makes FortiMail valuable to us."
"FortiMail is a stable product."
"Fortinet utilizes specialized processing units, which network faster and sample more efficiently compared to others."
"The technical support services are excellent."
"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."
"With Trend Micro email security gateway, we can deploy features like DLP and BEC."
 

Cons

"It is not easy to install."
"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."
"Online support sometimes takes up to a week to get back to you."
"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."
"Sometimes it takes a little bit too long to determine if an email is good or not. If they could shorten that time span, it'd be so much better. It does delay our email, which does not make users happy. That said, I would have to say we have not been blacklisted for quite a while now."
"I have little to say about possible improvements, but the configuration for content blocking could be better. So, for example, if the email includes the line "You have a Bitcoin", I would like it to be easier to block it before it enters an inbox. Fortinet could maybe offer better or simpler help on how to do this properly."
"Sometimes, the tool flags legitimate incoming traffic as spam."
"I believe there is room for enhancement in content and web security features."
"The solution's pricing could be improved."
"There is room for improvement in content filtration, expressions, file sharing, and policy configuration."
"There is room for improvement in content filtration, expressions, file sharing, and policy configuration."
"The product's pricing could be more flexible."
 

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."
"I find Fortinet FortiMail pricing reasonable. There's no additional cost apart from its standard licensing fees."
"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."
"Fortinet Fortimail has reasonable pricing."
"The annual cost is $55,000."
"This is a good solution and value for the money."
"The pricing is good."
"9,000 Euro per annum for Fortinet Mail and sandbox."
"Trend Micro is an expensive solution."
"I rate Trend Micro InterScan Messaging Security’s pricing a seven out of ten."
