SH
Chief Information Officer at a construction company with 1,001-5,000 employees
Has unified our IT teams by providing clear visibility into network vulnerabilities and accelerated remediation with real-world attack testing
One of the things that we've shared with Horizon is just the reporting. They've made a lot of changes over time, but when examining computers, most average normal people don't look at a computer and identify it as 114.82.117.180. They identify it as 'the printer for accounting.' When many of the reports give the very detailed technical IP address or serial number, that's really not helpful for anyone other than the person, the hands-on person that's trying to remediate it. All the managers, all the leaders, having information in that format isn't helpful. Being able to have information about what those devices are would be very helpful. There's a technical reason they can't just have an easy button because some people have really complicated networks. When examining things for the average company, the average executive, that 114 number, there's only one of those. But if examining an AT&T or a Walmart, it isn't unique. They haven't solved that problem. But for the 90% of companies, being able to have just a human readable name for all devices on your network in all of the reports all of the time would be the most beneficial.

Senior IT Security Engineer at a financial services firm with 5,001-10,000 employees
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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"My favorite feature about The NodeZero Platform is that it's autonomous, and it truly delivers on that promise—it can be set and forgotten while it performs its tasks, and it does exactly what it claims to do."
"The NodeZero Platform's real attack capabilities help identify vulnerabilities on my on-premise systems by adding an element of validation and offensive security testing on top of known vulnerabilities. The feature that allows security teams to fix and retest vulnerabilities instantly is very useful, even though it may not happen literally 'instantly.' It's a necessary tool for any organization to understand whether vulnerabilities are genuinely exploitable by attackers. With its near-real-time testing capabilities, it's an essential part of any security portfolio."
"For us, The NodeZero Platform is literally the single best security solution we have because the way that it works is we're able to scan every part of our network, both internally and externally, and then get completely actionable feedback that doesn't matter if it's for an application developer or a network admin."
"After the third party conducts the pen test, The NodeZero Platform is run, and it finds the same things they found and sometimes a few other things that they did not even identify."
"Honestly, it's one of the most transformational technologies we've implemented in our company."
"Overall, I'd rate NodeZero at nine to 9.5 out of ten."
"I rate the stability of the NodeZero Platform a ten out of ten."
"The NodeZero Platform's real attack capabilities help in identifying vulnerabilities on our on-prem systems because it provides actual vulnerabilities by attacking our systems."
"The platform provides all essential features for discovery and administration."
"Sandboxing gives us a chance to identify malicious behavior, especially for unknown vulnerabilities, although it's rarely needed as a last resort after all other security measures have failed."
"The most valuable feature of Trend Micro Deep Discovery is its complete end-to-end visibility of threats."
"Trend Micro Deep Discovery is a very specific product for threat intelligence with smart protection."
"There is no downtime or server vulnerability with this solution."
"The tool's most valuable feature is its collaboration with other products. Integrating with other security products was simple and easy."
"It is a very good solution. It is very light, and it is quite quick to figure out the problem in your network."
"This solution allows us to see anomalies, network traffic in our network, and zero-day threats."
 

Cons

"They've added a chatbot which isn't particularly useful, but when it can't answer questions, it forwards messages to human support."
"I encountered challenges with patch management, as we struggled to test and implement patches due to time constraints. This led to our patch management process being ineffective."
"The only issue we’ve encountered is that sometimes the scans take a long time to complete."
"One of the areas where improvement is needed is in the visibility and reporting for large enterprises."
"The areas for improvement for The NodeZero Platform involve integration and automation. It would be beneficial if it could integrate directly with vulnerability management tools that would allow the platform to automatically import data, identify vulnerable systems, and test targets immediately, potentially even enabling automated feedback loops for rescanning since the process is currently manual."
"You need to be cautious about what it scans, as it could potentially cause issues."
"Sometimes even their support doesn't know why we're seeing certain issues."
"The reports are quite useless."
"All issues we faced related to false positives regarding many hashes and URLs specifically for mail gateway and sandboxing, which led us to open a threat ticket with Trend Micro support for validation."
"All issues we faced related to false positives regarding many hashes and URLs specifically for mail gateway and sandboxing, which led us to open a threat ticket with Trend Micro support for validation."
"Scalability becomes an issue when managing a higher number of customers."
"The solution could be more stable and offer more security."
"The product's scalability feature needs to be improved, as it is an area in the product with certain shortcomings."
"The solution should support multiple platforms in Windows, Linux, and Mac. Customers can have different software types. The virtual environment should be able to install and analyze them. The tool also gives only a minimum level of extension support. It may not be able to extract files and give details about them. I would also like to see third-party product integration in the tool. The solution's current integration is only with Trend Micro products only."
"Some of the end users may not be technically proficient, so they occasionally face problems due to a lack of knowledge."
"The tool's configuration can be made easier."
 

Pricing and Cost Advice

Information not available
"The pricing is okay for some, and sometimes, some people find it expensive."
"Overall, Trend Micro Deep Discovery has proven to be a reliable solution that enhances our security posture while minimizing operational disruptions."
"Overall, the price is good."
"Trend Micro Deep Discovery is quite expensive compared to other endpoint security products."
"The price of the solution is lower compared to the competition."
"Its price is fine, but Trend Micro can improve the pricing in general. It is a hardware solution. It is based on the number of nodes, and according to the number of nodes, clients decide which box they should acquire. They have to renew their license every year. It is subscription-based."
"The tool’s licensing costs depend on the customers."
"The tool's licensing costs are yearly. There are no additional costs associated with the product."
