John Zupancic - PeerSpot reviewer
Pricing that is competitive, excellent technical support, and email security
They do a better job of distinguishing between what's real and what's not than most of the other solutions we've tried. They are very easy to use. We don't have as many problems with email security. They have some areas that could be improved. For example, we also use Zix email Encryption for email encryption, which was clunky and could be improved, but the email security itself has been excellent.
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.

Cons

"Email security checks contain a small number of false positives."
"Trend Micro's technical support has room for improvement."
"To improve Trend Micro Deep Discovery Email Inspector, it should have updates with better AI and ML-based integration."

"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)."
"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."
"Trend Micro's technical support has room for improvement. More efficient support should be provided, especially for standard support."
"The product's feature for message processing and blocking devices for bulk emails needs improvement."

"The solution's pricing is high, and I would rate it an eight out of ten."
"We pay for an annual subscription for this email security solution."
