Senior IT Security Engineer at a financial services firm with 5,001-10,000 employees
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.

Cons

"If there was better visualization in Flowmon Solution it would be good."
"The price of the license could be lower."
"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."
"Scalability becomes an issue when managing a higher number of customers."
"The solution could be more secure."
"Additionally, better scanning capabilities for third-party applications would ensure comprehensive security without the need for exclusions."

Pricing and Cost Advice

"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 tool’s licensing costs depend on the customers."

"The licensing cost is a bit pricey. We pay a yearly subscription."
"Overall, Trend Micro Deep Discovery has proven to be a reliable solution that enhances our security posture while minimizing operational disruptions."
"The price of the solution is lower compared to the competition."
