Delivers reliable email security with minimal maintenance and valuable threat intelligence
If you had asked me a few weeks ago, I would have said the user interface needed improvement, but we've just updated it. It looks really modern now, and it's a lot easier to use. At the moment, I don't have anything specific for improvement. Additionally, I would suggest different roles for users. We want the ability to lock down certain functions for certain user roles to prevent accidental changes, such as an apprentice accidentally deleting a customer.

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

"We've seen a 95 percent reduction in inbound spam and an equivalent reduction in inbound, malicious, phishing emails, and virus emails."
"The most valuable features of TitanHQ SpamTitan are how effective it is and how little maintenance it requires."
"We're now using SpamTitan Plus. It has an extra feature so that if you receive an email with a link, it goes to the TitanHQ server and that link is also checked. That is probably the best feature."
"Even though our organization is small, and the number of accounts that we protect with SpamTitan is small, the value that it offers is very great."
"SpamTitan provided all the features that we needed, and it was cost-effective."
"We have not had any issues with the product, the pricing is probably better than most vendors, and the support is definitely top-notch."
"It lowers the amount of junk email you have to go through and delete."
"We like to stick with SpamTitan for anti-spam, because it gives us the least problems and less false positives compared to other solutions."
"Trend Micro is a very good product."
"The best features of Trend Micro Deep Discovery Email Inspector include its reliability."
"I would rate the solution's stability at ten out of ten."
"The most valuable feature of Trend Micro Deep Discovery Email Inspector is the simple analysis of phishing emails."
"I like that it is very user-friendly and easy to install."
"It can effectively monitor outbound and inbound devices."
"I highly recommend Trend Micro Deep Discovery Email Inspector due to its security and scalability features."
"I find Trend Micro to be a good solution for security purposes."
 

Cons

"The interface looks a little dated and could be modernized."
"The user interface is good, but it could use some improvement."
"Sometimes when I'm trying to pull up reports, the speed can suffer."
"Its GUI can definitely be improved. As the administrator of the product, the GUI isn't very logically built. If you need something, you don't have one menu where you can say, "Well, this relates to our customers," and manage everything for your customers in that interface. The naming and placement of some of the menus need improvement. For example, if I'm looking for a log to take a look at what has passed through the filter of a specific customer, I get these ZIP-packed files that I can't use for anything. I have to look under history instead. The naming of some of the features is off by a lot."
"We are using the data center version with a dedicated server. It would be more user-friendly if SpamTitan were centralized. That is, TitanHQ should have a SaaS model for SpamTitan."
"If they had a little more documentation explaining how to use regex, or if they could include that inside of the cloud interface so that it generates regex code based on the parameters you input, that would be a lot more useful for people who aren't familiar with coding languages and HTML."
"Emails from companies we work with often get flagged, and I have to go in and release them. For example, I made a hotel reservation today from Marriott that got blocked. I'm sure hotels spam people, but I wish there was a way to know that the email was to confirm my reservation and for it to allow that through."
"When an email is quarantined, there are a couple of different search filters to help find what you're looking for. Having more choices would be helpful because as it is now, we can search for inbound or outbound, the score, the subject, and the email address."
"Trend Micro Deep Discovery Email Inspector could improve by making it easier to use. Microsoft solutions are easier to use."
"To improve Trend Micro Deep Discovery Email Inspector, it should have updates with better AI and ML-based integration."
"The product's feature for message processing and blocking devices for bulk emails needs improvement."
"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 dashboard could be improved to match the quality of Check Point Harmony's dashboard."
"Trend Micro's technical support has room for improvement. More efficient support should be provided, especially for standard support."
"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."
"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."
 

Pricing and Cost Advice

"The pricing was much more competitive than other solutions, so I was like, "Okay, let's give it a try.""
"They give you an update without charging you more for it, which is awesome. I like that a lot. It makes you feel appreciated as a customer."
"Partner profitability is good with Titan HQ's partner program. This means that I recommend it to clients who trust me. My time and effort to educate them is compensated by TitanHQ, who provides the solution to me at a lower price than what the public gets it at, then I can make some money."
"Its pricing is good. It's probably one of the most competitive anti-spam and anti-malware appliances out there for email. I was doing some looking around for pricing before I came to SpamTitan, and for the feature set, the price is very reasonable and competitive."
"We're satisfied with the pricing and licensing for SpamTitan."
"The price of SpamTitan is reasonable. It makes sense. There is no cost for me because I'm the managed service provider. The end customer pays the cost because we sell professional services to set up the whole solution, including SpamTitan and other products. Usually, it's part of a much bigger project."
"It's priced very reasonably. There are no additional licensing costs that affect me."
"Pricing is on par with other products, and it's reasonable."
"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."
"The price of Trend Micro Deep Discovery Email Inspector is less expensive than Microsoft solutions."
"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."
