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.

Reliability and threat intelligence make this solution competitive, but AI improvements can further enhance its effectiveness
The best features of Trend Micro Deep Discovery Email Inspector include its reliability. The second valuable feature is its built-in sandbox feature, allowing for inspection of incoming emails and attachments. The sandbox is an appliance that opens any attachment in an enclosed environment to assess its impact and potential for viruses. This protects the network from harmful threats. Trend Micro has a very large R&D team with excellent threat intel, allowing them to provide better solutions than some competitors. They understand emerging threats based on the information from their EDR. The key strengths can be summarized as reliability, a good integrated one-box solution that includes a sandbox, and their R&D capabilities and good ratings, which lead to better threat intelligence. The detailed threat intelligence provided by Trend Micro Deep Discovery Email Inspector is valuable in understanding the behavior and tactics of potential email threats.

Cons

"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."
"It can be easier to configure or connect to the cloud to report on the attachments."
"Sometimes, the tool flags legitimate incoming traffic as spam."
"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 web console management interface could be improved."
"Maybe FortiMail's integration could be better."
"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."
"The product's price is an area with shortcomings, making it an area where improvements are required."
"It could be more user-friendly, easier to install, and lighter on the network. I would say that for all products because you do not need technical expertise to take care of it. When you have a user-friendly solution, it makes it easier for the vendors or companies like us. We do not have to go to the client's site to attend to issues all the time. Because it is user-friendly, they can take care of it after some training."
"To improve Trend Micro Deep Discovery Email Inspector, it should have updates with better AI and ML-based integration."
"Trend Micro's technical support has room for improvement. More efficient support should be provided, especially for standard support."
"The dashboard could be improved to match the quality of Check Point Harmony's dashboard."
"Trend Micro's technical support has room for improvement."
"Trend Micro Deep Discovery Email Inspector could improve by making it easier to use. Microsoft solutions are easier to use."
"I would like to be able to send emails to a specific sandbox. This is a feature I would like to see added to the next release."
"The tool needs to incorporate faster response times for issue detection, more detailed reports, and better compatibility with older operating systems (e.g., Windows 7, 8, Server 2012)."
 

Pricing and Cost Advice

"The fees for Fortinet FortiMail can be complicated. However, overall the pricing is fair."
"The pricing is on the higher side."
"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."
"There is a license required for this solution and it is on an annual basis. I am satisfied with the price."
"The price is acceptable for the support license it includes."
"You need to pay additional fees for premium support."
"Pricing is based on initial license purchase and use volume."
"It's not as that expensive with the competitive different brands. The products sell a lot."
"It's an expensive solution, and you may not see a return on investment in a short period of time. However, you will see a return over a long period of time."
"The price of Trend Micro Deep Discovery Email Inspector is less expensive than Microsoft solutions."
"We pay for an annual subscription for this email security solution."
"The solution's pricing is high, and I would rate it an eight out of ten."
