Helpdesk Internal Systems Manager at Active IT Systems
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

"This sounds hyperbolic, but it's easily the best purchase that I've made since I started this business, 15 or 16 years ago."
"[One of the] things that make[s] it really attractive to end-users... is their ability to manage their own spam queues via the reports that SpamTitan offers. It allows them to determine what is spam and what isn't."
"It filters some of the spam."
"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 is a very easy product to use. There is one interface that services all our clients' health. Once learning the interface, we don't have to learn another one for each client. It is the same interface, which is valuable. Therefore, we find the single interface the most valuable since I have a very small team. I don't have one or two people dedicated to just SpamTitan. We all need to learn the interface and be fluent in it. So, having a unified single interface is a big deal for us. I don't have to teach my people five different interfaces in order to be managing a product. They use one interface for all our clients. It is a single pane of glass, which is huge for us."
"It is a great product for the price point that you are getting; it has a fantastic value and I would highly recommend it."
"We're very pleased with SpamTitan and the functionality that it has given us."
"I find Trend Micro to be a good solution for security purposes."
"The most valuable feature of Trend Micro Deep Discovery Email Inspector is the simple analysis of phishing emails."
"The best features of Trend Micro Deep Discovery Email Inspector include its reliability."
"It can effectively monitor outbound and inbound devices."
"The solution's most valuable features include visibility into the network and fast sandboxing technology for alerts, though response time can vary."
"I would rate the solution's stability at ten out of ten."
"Trend Micro is a very good product."
"I highly recommend Trend Micro Deep Discovery Email Inspector due to its security and scalability features."
 

Cons

"There are some minor technical aspects of the portals and management interface that could be improved, but there's nothing that prevents us from doing the job. BitDefender and similar products allow you to dive deeply into all the customers from a single console. Currently, I can only see our company on the console and not any of the customers. I have to log in somewhere else to see the customers, so that multi-tenancy is something I would like to see."
"I would like to implement a secondary delivery pool for mass mailings, having an alternate pool for mass mailing lists since there is only a single mail queue with SpamTitan. For example, if 10,000 emails are being sent, then the queue will be large. Unfortunately, without a secondary delivery pool, legitimate emails will wait in the queue to be delivered to my email. Therefore, I would like to have two queues: one for everyday emails and another for mass mailings. Now, I have to decide whether to buy a second SpamTitan license just for this reason because I am very satisfied with the functionality of SpamTitan overall and don't want to use another sender's appliance for this."
"The admin user interface is very granular. It can be difficult, on a layer-by-layer basis, to wrap your head around it."
"We had problems initially when first implementing eFaxing. We had problems trying to get eFaxes to be recorded correctly and come through correctly."
"We had to do some stuff with eFax in order to get eFaxing to come through. Had we known that ahead of time, we could have had that ironed out before we went live. However, we just didn't realize it was going to interfere with it. After we implemented it, we realized it was interfering with some of our eFaxes, so we had to go figure out why"
"SpamTitan's logging features could be improved. The logs are hard to deal with because you need to download the log as a text file. Then you need to search through this text file to find what you need."
"If you install and start using SpamTitan where the IT maturity is low, you'll have a lot of false positives, and it will ask the user for suggestions."
"The interface looks a little dated and could be modernized."
"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 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."
"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 product's feature for message processing and blocking devices for bulk emails needs improvement."
"To improve Trend Micro Deep Discovery Email Inspector, it should have updates with better AI and ML-based integration."
 

Pricing and Cost Advice

"As a small business, every penny is counted here... I really thought that something like SpamTitan would be more expensive, but it cost me about $70 (or about £60) a month. I'm more than happy to pay that."
"We're satisfied with the pricing and licensing for SpamTitan."
"Compared to the market, its price is fair."
"The pricing is ideal. A lot of other anti-spams are integrated in Exchange, counting technical mailboxes that are not sending any emails outside. So, they are not scanned and only for internal communication. SpamTitan only counts the emails that it scans. This is one of the best licensing models that I saw for anti-spam solutions because it is counting dynamically the number of emails that senders are sending. It counts these uniquely by week. It provides a very realistic picture. This is very useful because we are not counting the emails doing inbound or outbound notifications from our company."
"Cloud-based solutions charge per mailbox, which isn't ideal sometimes. A company could have 300 total mailboxes and only 50 in regular use, but they would have to pay the same for all of them. I want a cloud-based solution that gives a price based on the volume of email traffic."
"The pricing model was one of the reasons that we selected it. The solution was very effective at what it did and it was very cost-effective. My client saved in the 30% to 40% range by installing it, so the pricing is competitive."
"We're happy with their licensing model. It was a major factor in why we chose them."
"The pricing is great, but it has been increasing on a yearly basis. It is now close to that of Microsoft solutions. If it continues to increase, then clients may need to migrate to a different 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."
"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."
