Network visibility has transformed how we detect nation state threats and protect critical industry
Before Corelight recently started pushing some of the agentic features, querying at times could be a little difficult, depending on your mastery of log scale. However, I think with a lot of the artificial intelligence that they are building in, it is getting a lot easier to query in the platform. I would definitely encourage them to continue down that path where anybody can hop into the platform and start running queries, whether it is a simple instruction like I want this, and an artificial intelligence process can actually build the query and do it. I think that would be super powerful. Cyber skill sets are in high demand, and there is a huge backlog in cyber talent. We cannot fill all the positions we need. The easier we can make these cyber systems for people to pick up and be effective on, I think is really key. Explainability of data is hyper important. In the past few artificial intelligence related updates we have gotten from Corelight, that has been one of the first questions our team has asked every time or that I have asked: show me what the model is doing, show me how it came to this analysis. Within Investigator platform, they are able to walk through and see exactly what data the artificial intelligence pulled from where and why it did what it did as far as making its suggestions. They have definitely built their system with artificial intelligence in mind up front, and having that openness as one of the key features of any of their artificial intelligence and machine learning processes in the platform is important. The issue with black boxes is obviously hallucinations from artificial intelligence and just not being able to trace to ground truth. When we are talking about these cyber incidents and being able to do forensics, you need to be able to pinpoint and tie everything together, and black boxes really obscure that and prevent you from doing so. Corelight has done a really good job of making sure that everything is explainable and everything is mapped when it comes to leveraging any of their artificial intelligence features.

Long-term threat visibility has reduced customer incidents and supports steady recurring revenue
The real-time visibility on network traffic provided by Trend Micro Deep Discovery is good, and my customer is satisfied. My customers have indeed utilized the Threat Intelligence Sharing feature of Trend Micro Deep Discovery. The impact of the Threat Intelligence Sharing feature on overall defense and security is positive. The benefit that Deep Discovery brings to our organization is that we get fewer calls from customers, allowing me to focus on other businesses, and we receive year-on-year revenue for renewals.

Quotes from Members

Cons

"They can enhance the interface of the product. They can make it more interactive and also easier to use for feature access."
"In the next release, building a graphical user interface would be helpful."
"Before Corelight recently started pushing some of the agentic features, querying at times could be a little difficult, depending on your mastery of log scale."
"The solution’s architecture is complex and difficult to understand. There are multiple machines and VMs."
"Corelight hasn’t added features in a long time."
"Machine learning could be a good improvement, but it's very costly."
"It's an expensive solution and the price could be reduced."
"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."
"Trend Micro Deep Discovery is a very expensive solution, making it very hard to sell."
"The product's security features need enhancement."
"Some of the end users may not be technically proficient, so they occasionally face problems due to a lack of knowledge."

"The price of the solution is lower compared to the competition."
"Overall, Trend Micro Deep Discovery has proven to be a reliable solution that enhances our security posture while minimizing operational disruptions."
"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."
"Trend Micro Deep Discovery is quite expensive compared to other endpoint security products."
"The licensing cost is a bit pricey. We pay a yearly subscription."
