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.
