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

"If people or users are complaining that the network is slow, Flowmon can easily detect the cause of the network problem."
"The solution is both stable and scalable and we are happy with the product."
"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 stable."
"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."
"Flowmon is more easy to understand and helps find network issues more quickly."
"The solution has extension-based features that help it to analyze the environment. The environment can have different platforms like Windows, Linux, and Mac. The tool will give a report which can confirm the analysis of the issues. You can also get clear information on threats or suspicious files."
"The product is very easy to install."
"All in all, the variety of products provided by Trend Micro will give you a huge step up into checking and defending yourself from any threats."
"The most valuable features are the protection and that it is fast."
"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."
"The HTML file sandboxing is very good."
"Initial setup is easy. It can be done by yourself."
"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."
 

Cons

"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."
"I do not know the detailed pricing."
"If there was better visualization in Flowmon Solution it would be good."
"The price of the license could be lower."
"The solution could be more stable and offer more security."
"I am not aware if Trend Micro Deep Discovery provides any return on investment or cost reductions; it may not be beneficial in terms of finance."
"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 integration with third-party tools to improve the visibility of the dashboards."
"The solution is not scalable as it is an agent product rather than a product designed for scalability."
"Trend Micro Deep Discovery is a very expensive solution, making it very hard to sell."
"The product's scalability feature needs to be improved, as it is an area in the product with certain shortcomings."
"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."
 

Pricing and Cost Advice

"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 could be better."
"The licensing fee accrues only once, but that of support is annual."
"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."
"Compared to its competitors, Trend Micro Deep Discovery is a little expensive."
"Overall, the price is good."
"The price of the solution is lower compared to the competition."
"The tool’s licensing costs depend on the customers."
"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."
"The tool's licensing costs are yearly. There are no additional costs associated with the product."
