Ensuring long-term reliability while seeking internal email management enhancements
Prisma is a commercial name of the firewall now, but we don't work with the cloud product. Only our company is using it and we do not recommend it to customers. For us, it's transparent because it's a cloud product, so we don't really know the version as it's always updated. We have not had any problem, but it's difficult to report on what's going on because some days they can wash out perhaps 100 mails, and then it's difficult to say how many attacks you have reached. The right email has been washed out and then nobody has complained. We do not use the Threat Visualization feature; as we are in MX, the mail is washed out before it is in the mail inbox of the user, thus avoiding any problem requiring a reservation. In fact, there is no integration with existing security frameworks. The only problem we can have is that as we have no API interface, there is no inspection of internal mail. I rate Trellix Advanced Threat Defense a nine out of ten.

Has improved email security through advanced filtration and timely threat detection
I work with Trend Micro Apex One. I have used the Deep Discovery's Sandbox analysis feature, and we utilize another appliance known as Deep Discovery Analyzer, abbreviated as DDA. This tool makes analysis for URLs and attachments contained in inbound emails, so whenever we receive an email with a URL or attachment, it will be analyzed by Trend Micro Deep Discovery Analyzer. In evaluating Deep Discovery's real-time visibility on network traffic, it is important to note that we applied our Deep Discovery Analyzer for Trend Micro to conduct sandboxing specifically for email channels only, and we do not utilize it for network channels. For network channel sandboxing, we use a solution called FortiAnalyzer, which belongs to another team called network security. I assess Deep Discovery's effectiveness in identifying sophisticated attack patterns by looking at how it handles high traffic loads, and how effectively it can use its instances and images to analyze numerous URLs and attachments simultaneously. Additionally, I evaluate its ability to maintain round-robin or load balancing across different analyses without leaving samples queued for analysis. The performance is critical when the product updates for signatures are up-to-date, as this aids in the detection and classification of URLs and attachments without delay in the analysis process. On a scale of one to ten, I rate Trend Micro Deep Discovery a nine.

Quotes from Members

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

Pros

"It is very scalable."
"It stops in excess of twenty-five malware events per month, all of which could be critical to the business."
"The fact that in 10 years, we have had no problem is the most valuable feature for us; it's really a washing machine, but the only problem we face is that it's difficult to report on this product."
"Provides good exfiltration, and is an all-in-one product."
"Its greatest strength is the DXL client which can rapidly disseminate attack information to all clients via the McAfee Agent instead of going through the ePO server."
"The most valuable features are the administration console and its detection and response module."
"It is stable and reliable."
"I recommend this solution because of its ease of use."
"The real-time visibility on network traffic provided by Trend Micro Deep Discovery is good, and my customer is satisfied."
"The product's initial setup phase was not difficult."
"Generally speaking, it just gives us a broad understanding of exactly what kind of threats occur. The submission point, analyzing point, and virtualization are within the environment that it supports. It helped us to improve our security levels and protect our internal network from any threats outside."
"The tool's most valuable feature is its collaboration with other products. Integrating with other security products was simple and easy."
"Trend Micro Deep Discovery Email Inspector includes its ability to perform mail detection and mail filtration against various email attacks such as phishing and spam, serving as an email gateway for both inbound and outbound traffic."
"The performance and stability are great."
"The platform provides all essential features for discovery and administration."
"The reporting is very good, providing detailed analysis in a short amount of time."
 

Cons

"I would like to see future versions of the solution incorporate artificial intelligence technology."
"The only problem we can have is that as we have no API interface, there is no inspection of internal mail."
"Lacks remote capabilities not dependent on the internet."
"This solution needs to be made "cloud ready"."
"We'd like them to be better at dealing with script threats."
"The initial setup was industry standard complex. It takes awhile and has a lot of planning involved. It could be simplified with product redesign."
"Make the ATD system a part of the whole product and take the whole thing onto the cloud. While it is there already, it is not to the same level as the on-premise version."
"There could be a tool that automatically updates all-new Microsoft IPs, which are available for free to connect to the client."
"All issues we faced related to false positives regarding many hashes and URLs specifically for mail gateway and sandboxing, which led us to open a threat ticket with Trend Micro support for validation."
"The main issue is its high cost."
"The solution could be more secure."
"I would like the ability to analyze all files in our internal network, at the same time on different operating systems. Not just three of them, but as many as possible."
"Additionally, better scanning capabilities for third-party applications would ensure comprehensive security without the need for exclusions."
"The product's scalability feature needs to be improved, as it is an area in the product with certain shortcomings."
"Trend Micro Deep Discovery is a very expensive solution, making it very hard to sell."
"The stability of the solution could be improved. It should be 100% stable, but it's not there right now."
 

Pricing and Cost Advice

"The product is expensive, but it is better than the rest of them in the industry."
"Our licensing fees for this solution are approximately one million dollars per year."
"The pricing is okay for some, and sometimes, some people find it expensive."
"Overall, the price is good."
"The price of the solution is lower compared to the competition."
"Trend Micro Deep Discovery is quite expensive compared to other endpoint security products."
"Overall, Trend Micro Deep Discovery has proven to be a reliable solution that enhances our security posture while minimizing operational disruptions."
"Its price is fine, but Trend Micro can improve the pricing in general. It is a hardware solution. It is based on the number of nodes, and according to the number of nodes, clients decide which box they should acquire. They have to renew their license every year. It is subscription-based."
"The licensing cost is a bit pricey. We pay a yearly subscription."
"The tool's licensing costs are yearly. There are no additional costs associated with the product."
