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.
Bilal Saleem - PeerSpot reviewer
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.

Quotes from Members

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

Pros

"The integration with FortiSandbox is good, and something that we utilize often."
"The antiphishing capabilities are very good."
"The most valuable features of Fortinet FortiMail are its virus outbreak prevention and FortiSandbox integration."
"The solution has a user-friendly interface. It is easy to deploy and handle. You can easily troubleshoot the issues of the solution."
"Its threat detection capabilities have been beneficial."
"Technical support is great. They are able to look at their patches and offer quick responses. We even have an account manager in the Middle East. They are very good."
"Fortinet FortiMail's most valuable features are its performance and security."
"The solution can scale."
"It can effectively monitor outbound and inbound devices."
"I highly recommend Trend Micro Deep Discovery Email Inspector due to its security and scalability features."
"I like that it is very user-friendly and easy to install."
"I find Trend Micro to be a good solution for security purposes."
"The best features of Trend Micro Deep Discovery Email Inspector include its reliability."
"Trend Micro is a very good product."
"I would rate the solution's stability at ten out of ten."
"The most valuable feature of Trend Micro Deep Discovery Email Inspector is the simple analysis of phishing emails."
 

Cons

"The solution's pricing is flexible and can be adjusted for African utility companies. Microsoft often offers special pricing formulas for African governments and organizations and it is similar to Fortinet FortiMail. In my country, government institutions receive discounted pricing from Fortinet FortiMail."
"High Availability needs improvement."
"They should add a lot of threat-intelligence feeds from different sources - not only from one source (FortiGuard)."
"The infrastructure could be improved."
"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."
"Fortinet FortiMail could improve general user management. There are no password policies for users."
"The product could incorporate even more artificial intelligence to enhance the functionality, but it is a competetive and intelligent product as it."
"It is not easy to install."
"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."
"The dashboard could be improved to match the quality of Check Point Harmony's dashboard."
"Trend Micro's technical support has room for improvement. More efficient support should be provided, especially for standard support."
"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."
"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."
"The product's feature for message processing and blocking devices for bulk emails needs improvement."
"Trend Micro Deep Discovery Email Inspector could improve by making it easier to use. Microsoft solutions are easier to use."
 

Pricing and Cost Advice

"9,000 Euro per annum for Fortinet Mail and sandbox."
"The licensing model for this solution is better because it is based on the box and not the number of users."
"There is a license required for this solution."
"The product's licensing part depends on the number of mailboxes and the hard disk needed by customers. The cost of the license depends on the number of mailboxes and the number of emails."
"The solution is reasonably priced compared to one of its competitors."
"I have no information on pricing for the competition because right now, my company is working only with Fortinet, but I can say that in general, the price for Fortinet FortiMail was accepted by the customers easily. The POC is also important when a customer is buying a solution. The customer wants to see how the product runs, and as Fortinet FortiMail is a stable product that runs without big issues, it has a bigger chance of getting chosen by customers over its competitors, even if its price may be a little higher. Pricing for the solution is competitive. Sometimes it's less, sometimes it's a little bit higher, but it isn't far from what other solutions charge."
"Fortinet FortiMail has an annual license agreement."
"It is a fairly priced product, considering what it does. The product offers good value for the money users spend on it."
"The solution's pricing is high, and I would rate it an eight out of ten."
"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."
