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.

Long-term threat visibility has reduced customer incidents and supports steady recurring revenue
The real-time visibility on network traffic provided by Trend Micro Deep Discovery is good, and my customer is satisfied. My customers have indeed utilized the Threat Intelligence Sharing feature of Trend Micro Deep Discovery. The impact of the Threat Intelligence Sharing feature on overall defense and security is positive. The benefit that Deep Discovery brings to our organization is that we get fewer calls from customers, allowing me to focus on other businesses, and we receive year-on-year revenue for renewals.

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 environment is imported inside the sandbox and in this way, Trend Micro is the leader in the world's markets of sandbox solutions."
"It is a very good solution. It is very light, and it is quite quick to figure out the problem in your network."
"The most valuable feature of Trend Micro Deep Discovery is its complete end-to-end visibility of threats."
"The reporting is very good, providing detailed analysis in a short amount of time."
"Initial setup is easy. It can be done by yourself."
"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 real-time visibility on network traffic provided by Trend Micro Deep Discovery is good, and my customer is satisfied."
"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"
"I would like to see integration with third-party tools to improve the visibility of the dashboards."
"The solution could be more stable and offer more security."
"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."
"There are certain aspects of flexibility in the policies that should be added to Deep Discovery."
"This solution could be improved with faster technical support and cheaper licensing prices."
"The product's security features need enhancement."
"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 main issue is its high cost."
