Featured Reviews

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.
Nadeem Syed - PeerSpot reviewer
Offers comprehensive security, easy integration, and good support
It integrated easily. About 99% of the time, we do not face any challenges in integrating any product of Trend Micro with the existing network. It is usually compatible with all kinds of networks. They have recently added AI to all Trend Micro products. It makes life a little bit easier by catching viruses, providing solutions, and helping out whenever you are stuck somewhere. It is one of the very good features they have right now. For example, one of our clients experienced a network attack and became confused about resolving the issues. The AI was helpful by suggesting initial steps to solve the problem.

Cons

"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 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. More efficient support should be provided, especially for standard support."

"The solution's interface, which we get from an admin perspective, sometimes gets confusing."
"The initial setup was straightforward. This is a virtual appliance, it takes a short time to deploy the solution. However, it is not difficult if you understand the technology. You must have good knowledge of the email security area to set up the product correctly. There are many features in this solution and a high risk of having mistakes with the configuration."
"There is a limitation when customers are using their email from a third-party solution that isn't from Trend Micro."
