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

"The solution is stable."
"The artificial intelligence and automatic detection system in Flowmon Solution are perfect for every, type of customer, such as government and commerce."
"The solution is both stable and scalable and we are happy with the product."
"Flowmon is more easy to understand and helps find network issues more quickly."
"It is an open platform, so in terms of integration, we are quite happy. We can integrate it with other SNMP solutions. We can also integrate it with security solutions, such as a SIEM solution."
"If people or users are complaining that the network is slow, Flowmon can easily detect the cause of the network problem."
"As a security product, managing threats is crucial for my clients."
"One of the most valuable features is the performance, since, so far, we have not faced any issues with Deep Discovery."
"It is a very good solution. It is very light, and it is quite quick to figure out the problem in your network."
"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."
"Trend Micro is a good solution and our clients are happy with it."
"Fire Eye is incredibly expensive, and requires multiple appliances which together, scan far less protocols than DDi."
"The most valuable feature of Trend Micro Deep Discovery is its complete end-to-end visibility of threats."
"This solution allows us to see anomalies, network traffic in our network, and zero-day threats."
 

Cons

"I do not know the detailed pricing."
"It would be helpful to have more details about the monitoring of the infrastructure. It should have support for SNMP. This is something that is currently not there in the product."
"The price of the license could be lower."
"If there was better visualization in Flowmon Solution it would be good."
"The solution needs to be able to integrate better with third-party infrastructure."
"Trend Micro Deep Discovery is a very expensive solution, making it very hard to sell."
"I would like to see integration with third-party tools to improve the visibility of the dashboards."
"Trend Micro can improve the pricing in general. There is nothing else they can add or improve in the solution."
"Additionally, better scanning capabilities for third-party applications would ensure comprehensive security without the need for exclusions."
"The solution could be more secure."
"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."
"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."
 

Pricing and Cost Advice

"The price of the solution could be better."
"The licensing fee accrues only once, but that of support is annual."
"It works with a permanent license, and then you can pay for the support. For the gold support, you need to pay yearly."
"The price of the solution is lower compared to the competition."
"The licensing cost is a bit pricey. We pay a yearly subscription."
"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."
"Overall, the price is good."
"The tool’s licensing costs depend on the customers."
"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 tool's licensing costs are yearly. There are no additional costs associated with the product."
