Great protection, good privacy, and helpful support
The only thing I would like is a way to open the email that is going to quarantine. Based on the level of security, they cannot open the email to check the message. Even for the administrator, you have to create a security copy to be sent, which will lock the log support. It's not easy for an admin to check and decide if the email is good or not. That is the only thing that I'm seeing could be improved. Basically, ESET doesn't have the ability to let the administrator release an email showing the message on the email. It's not possible. If you want to have an email review, you have to select an option to send a copy. In the way that they designed the system, for security, they are not letting anyone even have the admin privileges to make this happen. Privacy is at a really high level.

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.

Pros

"We are close to having 99% or 98% detection."
"The most valuable features are the precision of detection and the level of customization of the policy."
"I would rate the solution's stability at ten out of ten."
"I highly recommend Trend Micro Deep Discovery Email Inspector due to its security and scalability features."

"The most valuable feature of Trend Micro Deep Discovery Email Inspector is the simple analysis of phishing emails."
"I find Trend Micro to be a good solution for security purposes."
"It can effectively monitor outbound and inbound devices."
"The solution's most valuable features include visibility into the network and fast sandboxing technology for alerts, though response time can vary."
 

Cons

"It's not easy for an admin to check and decide if the email is good or not."
"The specific domain file for Apache needs to be well-defined."
"To improve Trend Micro Deep Discovery Email Inspector, it should have updates with better AI and ML-based integration."
"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)."
"Trend Micro's technical support has room for improvement."
"The dashboard could be improved to match the quality of Check Point Harmony's dashboard."
"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."
"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 product's feature for message processing and blocking devices for bulk emails needs improvement."
"Trend Micro's technical support has room for improvement. More efficient support should be provided, especially for standard support."

"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."
