Robert Melendez - PeerSpot reviewer
Enhances email security and has a very simple and easy-to-use UI
Spam protection is the most valuable feature. We have implemented the tool to enhance our email security. It helps prevent phishing attacks. The anomaly detection capabilities are baked into the security platform. The product integrates wonderfully with Microsoft 365. It's built right on a cloud platform and works almost natively. The solution has a very simple and easy-to-use UI. The tool appears extremely powerful and has a good solid feature set. It catches things that are bad for my environment. The user interface is good the way it is. If the solution continues down that path, I see no problems with the way it is going. It feels like a mature product.
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

"The customizable rules allow you to change aspects."
"The program has reduced the dangers related to phishing, malware, ransomware, and other vulnerabilities."
"Easy to use for non-technical users."
"It can retract unsafe emails and remove them from the entire communication channel."
"It is simple to deploy this platform and interact with the set features."
"Email encryption enhances end to end security of any data before it passes through the networking system."
"The most valuable feature of Avanan is its Anti-Malware solution for Office 365, and box.com."
"Avanan is a stable software. My company hasn't faced any issues, bugs, or problems with the performance of Avanan."
"The solution's most valuable features include visibility into the network and fast sandboxing technology for alerts, though response time can vary."
"The best features of Trend Micro Deep Discovery Email Inspector include its reliability."
"Trend Micro is a very good product."
"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 find Trend Micro to be a good solution for security purposes."
"I would rate the solution's stability at ten out of ten."
 

Cons

"In Avanan, the email channel is one of the channels where data leakage happens, and they need to consider it from a DLP perspective."
"It should reduce the amount of time needed for thorough scanning."
"It is complicated for new users unfamiliar with the modern cloud networking infrastructure."
"Being cloud first and because we are in the movie business, we use a lot of Macintoshes. So, there is absolutely no reason for us to have Active Directory whatsoever. However, if you are using Office 365, you must have Active Directory in order to reset passwords. Even though we have a single sign-on provider, we must have Azure Active Directory for Office 365, which is really stupid. As a cloud application, you would think that I don't need Active Directory, which I don't need for anything else except Office 365. We have one server inside that space to help us manage Active Directory just for Office 365. This is a very sore point, but it is what it is."
"It is very difficult to find the required documentation."
"Integration with various SaaS offerings, who are leading in the SaaS market."
"There are times when we have false positives."
"Sometimes it seemed like the allow list wasn't working. I've created many allow list rules however, they still seem to be blocked; the same is true with the blocked list rules."
"Trend Micro's technical support has room for improvement. More efficient support should be provided, especially for standard support."
"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."
"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."
"To improve Trend Micro Deep Discovery Email Inspector, it should have updates with better AI and ML-based integration."
"The dashboard could be improved to match the quality of Check Point Harmony's dashboard."
"Trend Micro's technical support has room for improvement."
"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 of Avanan is reasonable."
"Having the flexibility and modeling to do the pricing that best fits the needs of the organization is incredibly ideal. That is what Avanan does. They know exactly how many users are using it, etc. We can tune the invoicing associated with how we are using the product so we can charge it back to the shows appropriately."
"The product is not the cheapest in the market."
"Good pricing arrangement as an SaaS offering."
"Avanan’s price is comparable to Barracuda."
"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."
"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."
