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."
"Setup is straightforward with the same reliability and scalability as the firewall series."
"Trend Micro Deep Discovery is a very specific product for threat intelligence with smart protection."
"The platform provides all essential features for discovery and administration."
"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 tool's stability and performance are good."
"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."
"The most valuable feature of Trend Micro Deep Discovery is its complete end-to-end visibility of threats."
"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."
"Deep Discovery is scalable and compatible with other products. It's crucial to have that compatibility because it's an integral part of our security solution. It integrates smoothly. The interface is user-friendly, so administration is simple."
 

Cons

"Lack of tools to help educate end users"
"Lack of tools to help educate end users"
"Trend Micro can improve the pricing in general. There is nothing else they can add or improve in the solution."
"I would like to see them create a rule where it could integrate with the network and start mitigating with auto-detection."
"Additionally, better scanning capabilities for third-party applications would ensure comprehensive security without the need for exclusions."
"Deep Discovery is easy to manage, but there is still room for improvement on the administration and operations side. Competing products have a cleaner interface that makes it easier to manage their products. Trend Micro offers a lot of features in one product suite, but it can be unwieldy for the customer to manage all that with a single interface."
"I would like to see them create a rule where It could integrate with the network and start mitigating with auto-detection."
"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."
"Sometimes there needs to be a stability test done. We did tests and checked up to around 20 or 25 samples; out of those tests, two missed and were later detected on the endpoint, so it is not completely stable and it misses things."
"The solution could be more stable and offer more security."
