Email security has protected financial data and provides clear tracking for every branch message
The areas of Cisco Secure Email that could be improved or enhanced are the slowness in the console. I don't think it was a database error or something, but we feel some slowness in configuring DLP and other content filters compared to other consoles. It may have been due to on-premises, but it was much noisy at some times while configuring DLP. When we tried to configure a DLP policy, the console became much slower. In that case, we cannot see what had happened in the mail which was blocked at that time. It may take nearly an hour to get back to normal while configuring policies. That is the major issue in the product.

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.

Helpful support, and useful dashboards
They offer a feature called SmartLink neutralization. I have tried it before. It seemed to work most of the time; however, I had a few users for whom it just wouldn't work. Whenever they click on a link, it stays on the MetaDefender page, saying that it's scanning it and never moves forward. I haven't tried it in a while since then. Since I can't turn it off on a per-user basis, I had to turn it off globally. I have certain exceptions for not doing the sanitization, and how to set those up is not intuitive. It would be useful if there were a better way of doing that. Using digital certificates is hard. It would be better if it used Windows Servers' built-in certificate management.

Quotes from Members

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

Pros

"There were detailed logs available. That was a seriously good feature... It turns out these were actually spoof emails that came into our environment. I got to know about them from the log system."
"The strong point of the solution is that we hardly get any spam emails because of Cisco Secure Email."
"The most significant enhancement we've gained is in terms of security through the upgrade we received."
"I love the Advanced Malware Protection feature. It works very well... The appliance has more security such as SDF, DKIM, DMARC, and encryption."
"It has an intuitive, clear graphical interface where you can deploy your policies and understand the overall flow. There are a lot of things that you cannot handle on the graphic interface, like message filters. For this, you need to go to a lower level where you have more power, like command line interface. So, this solution has the best of both worlds. There are not a lot of bells and whistles. It is more practical with access to most features that you can configure."
"The solution works well."
"The most valuable feature is the different content filters we are using, such as DKIM."
"Overall, the ease of migration to Cisco's cloud email security from the on-prem solution was a positive experience."
"This is a very stable product and all of our customers are happy that we use it."
"For now, as per our experience with FortiMail in handling a large number of emails and spams as well, in the past three years, we have been protected and saved from any attacks from the outside."
"Fortinet’s support services are good."
"Fortinet utilizes specialized processing units, which network faster and sample more efficiently compared to others."
"With the Fortinet FortiMail solution, you have a lot of advantages because of the effectiveness of security."
"The spam filtering is great."
"We have definitely seen ROI. My emails are safer. We don't have any more spam or phishing emails. The users are safe now. I don't have to worry about what emails my team is getting. It makes my life easier."
"We found the initial setup to be mostly straightforward."
"The most valuable feature is called summary reconstruction which is used to deliver encrypted files to users."
"The most valuable feature of MetaDefender Email Security is the CDR. Customers purchase this solution specifically for data communication, as the other features can be obtained through other technologies that most customers already possess. Therefore, data communication serves as the foundation for the platform."
"The sanitization is very good."
 

Cons

"The area of license renewal should be improved. We normally renew our license every year."
"The user interface could be updated."
"In future releases, I would like to see two main improvements come to mind. First, the current solution requires maintaining two separate operating systems for FTD, which can be cumbersome. I'd love to see a single operating system for the FTD box."
"The user interface of the Email Security Gateway should be improved."
"Typically, in a phishing email, they try to use a name everybody's going to recognize, like the CEO's name or the CFO's name... With this appliance, the way it's designed at the moment, for us to really stop that with any level of confidence, we have to build a dictionary of all the names of the people we want it to check, and all the ways they could be spelled. My name would be in there as Phillip Collins, Phillip D. Collins, Phillip Dean Collins, Phil Collins, Phil D. Collins. There could be eight or 10 variations of my name that we'd have to put in the dictionary. There's no artificial intelligence to say "Phil Collins" could be all these other things, and to stop phishing from coming through in that way."
"The primary areas for improvement are the pricing and the complexity of deployment."
"The areas of Cisco Secure Email that could be improved or enhanced are the slowness in the console."
"Cisco Secure Email can be improved from the administrator's point of view. Usually, you have to work with different areas, and they can try to make it easy for the administrator to use different functions."
"The Ui isn't that intuitive."
"In the future, I would like it if there's a possibility to lower the price of the bandwidth and UTM. It is quite expensive."
"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."
"The solution lacks to provide more visibility when there is a problem, and it needs to be tracked."
"The product's cybersecurity features could be better."
"It can be somewhat difficult to prepare precise or very deep rules to improve security, though the product is very good."
"Fortinet FortiMail's technical support team has shortcomings and needs improvement."
"What's missing in Fortinet FortiMail is some sandbox information for some of the emails. It's probably configuration-based, where it could be configured on some emails. For example, there was malware in some emails that weren't detected in some of the Fortinet FortiMail sessions, but it should have been configured from my company's end to better catch scam emails, but overall, the solution is okay. At the moment, my company is okay with the current Fortinet FortiMail offerings, but in the past, because of a lack of understanding, my team wasn't able to quickly implement the geographical IP blocking feature. It was time-consuming to implement that feature, but that wasn't a fault of Fortinet FortiMail. The issue was from my team's end, but just by emailing the support team, that issue was resolved, so right now, there isn't any additional feature I'd like added to Fortinet FortiMail."
"They offer a feature called SmartLink neutralization. I have tried it before. It seemed to work most of the time; however, I had a few users for whom it just wouldn't work. Whenever they click on a link, it stays on the MetaDefender page, saying that it's scanning it and never moves forward."
"Although the number of AV engines is good, it could be better."
"The DLP should be upgraded and has room for improvement."
