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.

Built faster threat response and improved visibility with real-time monitoring and flexible deployment
TrendAI Vision One allows us to monitor attacks in real time, which is a significant benefit. We can quickly see where the attack is coming from. TrendAI Vision One enables us to use different products with a flexible license. For example, if a customer is using endpoint security and wants to switch to another solution, they can instantly use a different Trend Micro product, such as email. TrendAI Vision One has helped to reduce the time to detect and respond to different threats, as it can respond to attacks very quickly. With playbook templates, in cases of recurring attacks, responses can be made quickly using predefined playbooks. TrendAI Vision One has helped to reduce noise from false positives. There have been false positives before, but it was due to the customer not telling us which app they were using. Best practice configurations must be applied properly to avoid such issues. TrendAI Vision One helps customers consolidate the use of security vendors and reduce silos by offering one platform for all product management.

Quotes from Members

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

Pros

"It's easy to create additional dashboards specific to supporting specific tasks."
"The most valuable feature is the embedded IDS from Suricata."
"Our company has seen massive improvements in cybersecurity position for our clients."
"Corelight makes much easier the remediation of cyber attacks; instead of facing a chaotic amount of logs, Corelight provides correlated metrics that allow pivoting to find, in seconds, all the data related to an alert, detection, or asset."
"Corelight Open NDR has had a positive impact on my company, providing visibility as the Suricata engine can scan huge volumes of traffic, including north-south and east-west, revealing signatures and exposures I was not expecting and enabling me to catch them with Suricata alerts."
"It is easy to deploy and easy to handle."
"Technical support seems to be good."
"It's an easy way for us to get visibility in a client's environment."
"I can prevent my environment from different types of attacks based on what I see in the Vision One console."
"I like XDR's workbench feature and observed attack technique. It generates an alert once certain conditions are met. For example, let's say there's a threat called malicious.exe being deployed on your system. It will generate an alert with information like the file path, location, hash, etc. You also see a relational matrix showing how that file was executed and which processes were installed."
"The proactive approach is the best feature."
"I like that it is a comprehensive security solution with a lot of features. You can say XDR is an end-to-end security solution with endpoint security. It includes all your servers, networks, and other devices. The endpoint security solution does not cover this. Plus, machine learning and features like that are the main things in XDR solutions."
"The comprehensive overview of the security status is the most valuable feature of TrendAI Vision One, and its ability to provide centralized visibility and management is quite good because all the relevant data are present, providing everything needed."
"The most valuable feature of Trend Vision One is response management; when there is a malware issue, we need to isolate the endpoint, which I can do through response management. I"
"Trend Vision One offers centralized visibility and management across all protection layers, providing a holistic view of our environment and enhancing visibility across the entire infrastructure."
"It helps us with investigations."
 

Cons

"In the next release, building a graphical user interface would be helpful."
"The solution’s architecture is complex and difficult to understand. There are multiple machines and VMs."
"Machine learning could be a good improvement, but it's very costly."
"They can enhance the interface of the product. They can make it more interactive and also easier to use for feature access."
"Corelight hasn’t added features in a long time."
"It's an expensive solution and the price could be reduced."
"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."
"Currently, there is nothing specific that needs improvement. Their support is very cooperative, and they provide an educational portal for learning the solution. However, deployment could improve by considering customer environments that are not fully updated."
"They should increase their potential for third-party integrations."
"Support is low. When we raise a ticket for P0 or P1, the response tends to be quite late."
"The solution could always be made to be more secure."
"Having more variables within the playbook would be useful. It would allow us to have more refined playbooks for the business. It would allow us to take stronger action through a playbook. It will give us confidence to target a particular area of business where our risk tolerance might be higher or lower. We would like to have more granular playbooks."
"The price could be lower."
"Our developers were understandably frustrated that they couldn’t debug code for a month and a half, which impacted our project timelines."
"The area where I think TrendAI Vision One can improve is the technical support."
 

Pricing and Cost Advice

"It's a yearly fee and depends on what you are looking for."
"Trend Vision One offers a competitive price-to-value ratio."
"They've introduced a credit system, where we purchase credits and then allocate them to the specific services we need active."
"The cost is considered fairly priced."
"Trend Micro XDR has a good price, and on a scale of one to five, I would rate it a four out of five in terms of price."
"Trend Micro XDR is expensive, and you have to pay for it yearly."
"The pricing for Trend Vision One is reasonable."
"Trend Micro's cost is higher than other solutions. That is the main reason why we need to switch to another solution."
"I feel that Vision One is a bit expensive. As for the pricing or licensing, I would rate it a seven out of ten."
