Complements any firewall
The core processors are there and it's able to generate reports for that. It also complements any kind of firewall. For example, if an end user is using Palo Alto as a firewall, they'd need another layer of firewall like the S-Series that will protect internal servers. It's something that complements any firewall in the market.

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

"Setup is straightforward with the same reliability and scalability as the firewall series."
"The product is very easy to install."
"The performance and stability are great, and we've been able to maximize the bandwidth allocated to us while Trend Micro has been very helpful in guiding us on what we need and where to place all the missing sniffing ports."
"The platform provides all essential features for discovery and administration."
"The reporting is very good, providing detailed analysis in a short amount of time."
"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 real-time visibility on network traffic provided by Trend Micro Deep Discovery is good, and my customer is satisfied."
"Trend Micro Deep Discovery is a very specific product for threat intelligence with smart protection."
"Sandboxing gives us a chance to identify malicious behavior, especially for unknown vulnerabilities, although it's rarely needed as a last resort after all other security measures have failed."
 

Cons

"Lack of tools to help educate end users"
"The product's scalability feature needs to be improved, as it is an area in the product with certain shortcomings."
"The solution should support multiple platforms in Windows, Linux, and Mac. Customers can have different software types. The virtual environment should be able to install and analyze them. The tool also gives only a minimum level of extension support. It may not be able to extract files and give details about them. I would also like to see third-party product integration in the tool. The solution's current integration is only with Trend Micro products only."
"The solution could be more stable and offer more security."
"The main issue is its high cost."
"The product's security features need enhancement."
"The stability of the solution could be improved. It should be 100% stable, but it's not there right now."
"The tool's configuration can be made easier."
"Trend Micro can improve the pricing in general. There is nothing else they can add or improve in the solution."

"Overall, the price is good."
"The pricing is okay for some, and sometimes, some people find it expensive."
"Overall, Trend Micro Deep Discovery has proven to be a reliable solution that enhances our security posture while minimizing operational disruptions."
"Trend Micro Deep Discovery is quite expensive compared to other endpoint security products."

"The licensing cost is a bit pricey. We pay a yearly subscription."
