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.

Room For Improvement

Digital Guardian needs to enhance partner programs, policy simplicity, cross-platform features, resource efficiency, cloud integration, and technical support.
Trend Micro Deep Discovery faces challenges with integration, scalability, support, pricing, and requires improvements in usability and network capabilities.
The issue is that it works only with users or companies with more than 500 users.
Cyber Security Researcher at a tech services company with 11-50 employees
Digital Guardian can generate false positives initially, which can be significantly reduced through proper policy tuning and data classification.
Sr.Technical Support Executive at Digitaltrack Solution Private Limited
The solution is not scalable as it is an agent product rather than a product designed for scalability.
Owner at Darcom
There is no dedicated team in India for giving support for Trend Micro Deep Discovery.
Director at Business Automation Indore Private Limited
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.

Setup Cost

Digital Guardian is costly but ideal for enterprises needing strong data loss prevention, especially in manufacturing.
Trend Micro Deep Discovery [EOL] pricing is annual, node-based, varies by requirements, and opinions differ on its competitiveness.
The solution is very expensive.
Owner at Darcom
It is reasonably priced, not very expensive like Proofpoint or other vendors.
Senior IT Security Engineer at a financial services firm with 5,001-10,000 employees
Overall, the licensing cost of Trend Micro Deep Discovery was not on the higher side earlier, but now, since the competition has increased, we need to think about the prices.

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.
