Helps to detect and generate reports on phishing emails and saves from email compromises
We use the solution for marketing and brand protection.  I am impressed with the tool's discovery capabilities which help me find out who is sending the emails on the company's behalf. I also find the ability to detect and generate reports on phishing emails a valuable feature.  The product's…

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.

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

Pros

"I am impressed with the tool's discovery capabilities which help me find out who is sending the emails on the company's behalf. I also find the ability to detect and generate reports on phishing emails a valuable feature."
"It comes with a lot of helpful tips for complicated areas."
"It is really important for large companies to have the brand protection that is provided by Agari."
"If spam or some kind of malicious email gets past Mimecast and gets into our email environment, we can go into Agari and we can search for it."
"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."
"The solution's most valuable features include visibility into the network and fast sandboxing technology for alerts, though response time can vary."
"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."
"It can effectively monitor outbound and inbound devices."
 

Cons

"Some customers in the financial sector do not like the cloud solution because they don't want data to be transferred to a US-based cloud."
"The protocol is quite complicated, which may not be something that could be improved, but it would be better if it was simplified."
"The product's user interface is clunky. We have difficulty in finding what we need. I would also like to see automation in the onboarding processes."
"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."
"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."
"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)."
"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

"The tool is not expensive and I would rate its pricing a four out of ten."
"The pricing depends on the number of users; per how many mailboxes you have, but they're pretty negotiable with that, too."
"The price of the licensing is based on the volume of email."
"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."
"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."
