Trend Micro Deep Discovery offers mixed financial results but increases security with threat visibility, sandbox, and IDS enhancements.

Room For Improvement

Trellix needs improved customization, integration, and usability in its detection, reporting, and policy management for enhanced user experience.
Trend Micro Deep Discovery faces challenges with integration, scalability, support, pricing, and requires improvements in usability and network capabilities.
There should be improvements in AI intelligence, faster decision-making, and a more responsive technical support team.
Information Security Engineer at Nhq Distribution Ltd
It would be best if Trellix Network Detection and Response sensors were converted into a next-generation firewall with built-in capabilities for routing, switching, and Layer 7 functionality, as most next-generation firewalls today include these features.

There is no dedicated team in India for giving support for Trend Micro Deep Discovery.
Director at Business Automation Indore Private Limited
 

Setup Cost

Trellix's pricing is considered competitive but expensive, with straightforward licensing and efficient setup, potentially deterring smaller businesses.
Trend Micro Deep Discovery [EOL] pricing is annual, node-based, varies by requirements, and opinions differ on its competitiveness.
Trellix Network Detection and Response is an enterprise-grade security solution, so it represents a significant investment, but we believe that the value it provides in terms of threat detection, network visibility, and incident response justifies the cost.
Business development executive at Digitaltrack solution Pvt Ltd
The pricing model is not transparent, as they do not provide pricing ranges upfront, complicating the evaluation of costs across regions.
CyberSecurity Architect at a comms service provider with 51-200 employees
My experience with the pricing, setup cost, and licensing of Trellix Network Detection and Response is that they are very good and affordable for the customer range.
Network & Security Lead at Net-International
I do not consider it an expensive tool; its price is justified based on the capabilities that we receive when compared to another mail gateway or other vendors.
Senior IT Security Engineer at a financial services firm with 5,001-10,000 employees
The solution is very expensive.
Owner at Darcom
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.
Director at Business Automation Indore Private Limited
 

Valuable Features

Trellix Network Detection and Response enhances security with real-time detection, automation, and integration, reducing manual monitoring by 50%.
Trend Micro Deep Discovery provides real-time threat detection, seamless integration, scalability, and user-friendly interface for comprehensive network protection.

Trellix Network Detection and Response has positively impacted my organization by addressing performance issues, specifically by offloading heavy traffic inspection and SSL inspection through sensors due to the limitations of the firewall.

Business development executive at Digitaltrack solution Pvt Ltd
Continuous network insight has improved early threat detection and streamlined investigations
Overall, we have a positive experience with Trellix Network Detection and Response, but like any enterprise security solution, there are areas where it can continue to improve. One area would be user interface and dashboard customization. While the platform provides a lot of valuable information, new users can sometimes face a learning curve when navigating and investigating and creating customized views. More intuitive dashboards would simplify workflows and help analysts access critical information even faster. Another area for improvement is reporting and analytics. The existing reporting capabilities are useful, but more flexibility and customizable reporting options would make it easier to generate executive-level summaries, compliance reports, and operational metrics for different audiences.

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.
