Provides strong data protection with virtual patching and vulnerability assessments
I primarily use it to monitor database access, particularly in banking and similar environments. It ensures that IT personnel and others do not create unauthorized accounts or users. Collaboration security assists in tracking database access and alerts in case of suspicious activity One of the…
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

Cons

"I would like to see this solution become more flexible."

"In general, our company should make the tool more robust to protect our systems."
"The spam detection feature could be better."
"FireEye needs single sign-on. They say it's on their roadmap. They should also implement support for Microsoft Authenticator app for 2FA."
"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."
"Trend Micro's technical support has room for improvement."
"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 Deep Discovery Email Inspector could improve by making it easier to use. Microsoft solutions are easier to use."
"The product's feature for message processing and blocking devices for bulk emails needs improvement."

"I rate the product price as nine out of ten, where ten is the most expensive, and one is the cheapest. There is no need to pay any extra charges apart from the licensing costs."
"The solution requires a license to be purchased for every user."
"The cost is very high."
"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."
"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."
