Room For Improvement

Digital Guardian needs better Linux/Mac support, stability, compatibility updates, multilingual dictionaries, pre-sales support, partner program, and technical support.
Trend Micro Deep Discovery needs better integration, user-friendliness, scalability, pricing, support, speed, and IT infrastructure compatibility.
The solution is not scalable as it is an agent product rather than a product designed for scalability.

Highly customizable, helpful support, and multiple modules available
Digital Guardian is generally considered stable, with its robust data loss prevention capabilities being highly valued by organizations. However, as with any complex software solution, there may be occasional challenges in terms of compatibility with certain operating systems or applications. In such cases, it may be necessary to modify settings or entries within Digital Guardian to ensure optimal performance. Overall, Digital Guardian is a stable solution that can be highly customized to meet the specific needs and requirements of organizations. As with any software solution, regular maintenance and support from a team of experts is necessary to ensure optimal performance and stability.

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.
