Sentiment score

For vendor support, such as Fortra support, I would rate it a seven because all the support comes from different parts that sometimes have challenges meeting time zones, and sometimes they reroute to distributors and rely on partners.

The solution is not scalable as it is an agent product rather than a product designed for scalability.

We have multiple components such as Deep Discovery Email Inspector for mail gateways, Deep Discovery Analyzer for sandboxing, and Deep Discovery Inspector, which serves as an IDS detecting malicious network traffic.

Enterprise data protection has supported regulatory compliance and integrates with classification tools
In terms of functionality, many features are valuable in Digital Guardian, as the first thing for most customers is that they are using solutions such as Boldon James and Titus, which fall under the classification side, and Digital Guardian can easily integrate with this data classification solution and has a very granular level of configuration and policy tuning. Digital Guardian's data protection policies are indeed useful for my clients. Regarding Digital Guardian, I find it to be a very good solution, and in fact, it is an enterprise-level solution that has very tight integration with most of the products, with Fortra but also with others.

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.
