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

"Corelight is easy to use."
"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."
"The most valuable feature is the embedded IDS from Suricata."
"It's easy to create additional dashboards specific to supporting specific tasks."
"Technical support seems to be good."
"It is easy to deploy and easy to handle."
"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."
"I appreciate the value of real-time activity monitoring."
"I would definitely recommend Trend Vision One to others."
"The centralized visibility is good."
"Trend Vision One offers superior integrations, enhanced tool capabilities, and expanded solutions for network security, firewalls, and remote malware scanning."
"They were one of the companies, early on, that spent a lot of time integrating their toolsets, and I was really impressed with that... the endpoint management system could reach out to the Deep Discovery system on the network and pick up something that it perceived as a suspicious object."
"It is really straightforward, it is very easy to understand, and therefore, I highly recommend the solution."
"Trend Vision One has improved the way our organization functions by acting as both a monitoring tool and an antivirus, giving us insight on potential threats and enhancing our response time to security incidents."
"The most valuable feature is how the stack fully integrates all components of a solution."
 

Cons

"Corelight hasn’t added features in a long time."
"In the next release, building a graphical user interface would be helpful."
"Machine learning could be a good improvement, but it's very costly."
"It's an expensive solution and the price could be reduced."
"They can enhance the interface of the product. They can make it more interactive and also easier to use for feature access."
"The solution’s architecture is complex and difficult to understand. There are multiple machines and VMs."
"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 deployment process could be more streamlined over the existing infrastructure, as it was not as easy as we thought."
"I would like to have more integration with mobile device management."
"Regarding the initial setup process, I find it a bit complex with TrendAI Vision One. The integration of multiple products with TrendAI Vision One and configuring the policies is somewhat complex for a new user."
"The centralized dashboard has room for improvement."
"The SOAR features (Security Playbooks) are quite limited."
"Trend Micro XDR is expensive, and you have to pay for it yearly."
"Also, XDR should improve its coverage of the latest IOCs. Their suspicious object management works, but the coverage should be improved. It will take one or two months to get those things covered. XDR will detect on a behavioral basis, but these databases will not get updated daily like some other solutions. If you're dealing with new ransomware or malware, it may take around a month before it's covered by Trend Micro."
"The credits system is a little bit confusing to use. Licensing and feature management could be improved."
 

Pricing and Cost Advice

"It's a yearly fee and depends on what you are looking for."
"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."
"I do not have much visibility to it. It is definitely not a cheap product, but to my knowledge, it is out there with the big wigs in the industry, such as CrowdStrike, SentinelOne, and other EDR/XDR vendors. I had heard, and found out eventually, that their sales teams are very flexible, as more sales teams are."
"Trend Micro's licensing is outsourced to third-party vendors, resulting in price variations depending on the vendor."
"When we have a good product such as Trend Vision One, the price is fine."
"It is costly. It is not that affordable for a small organization. Only big organizations can afford it. It is a new feature that has been added, so its price is fair. Its licensing is probably subscription-based. It is for one or two years."
"Trend Micro XDR is expensive, and you have to pay for it yearly."
"Trend Micro XDR is expensive but we got a good deal from Trend Micro."
"Its price is very decent. It suits our requirements."
