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

"Technical support seems to be good."
"Our company has seen massive improvements in cybersecurity position for our clients."
"Corelight is easy to use."
"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."
"The most valuable feature is the embedded IDS from Suricata."
"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."
"It's an easy way for us to get visibility in a client's environment."
"I would recommend everyone to use Trend Vision One because it is the simplest GUI management; a network engineer with one year of experience can also manage Trend Vision One, and it can be deployed in any environment such as AWS, Azure, GCP, and also in a hybrid model."
"VisionOne offers a clear window into the security posture of our endpoints."
"XDR provided a much more deep view into what is actually happening."
"Trend Vision One is an integrated platform where I can get all the information about all the endpoints, whether it be a server, laptop, or desktop."
"It has good vulnerability protection."
"Trend Vision One has increased our endpoint visibility and reduced attack vectors, enabling us to identify and respond to vulnerabilities and threats faster, which has reduced our response time by an estimated 25–30%."
"Trend Vision One's greatest assets are its cloud-based platform and credit-based purchasing system, which eliminate the need for traditional licensing and procurement processes, enabling quick product acquisition within one or two days."
"This full security posture positions us well for our future security roadmap."
 

Cons

"The solution’s architecture is complex and difficult to understand. There are multiple machines and VMs."
"It's an expensive solution and the price could be reduced."
"In the next release, building a graphical user interface would be helpful."
"They can enhance the interface of the product. They can make it more interactive and also easier to use for feature access."
"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."
"Machine learning could be a good improvement, but it's very costly."
"Corelight hasn’t added features in a long time."
"The experience of first using Trend Vision One is really difficult due to the steep learning curve."
"Trend Vision One requires several enhancements for optimal performance."
"It is very expensive."
"Trend Micro doesn't have the next-generation firewall."
"The support documentation could be more comprehensive."
"Stability-wise, I feel there are times when it is not a stable solution, but I also had another client where it worked smoothly, and I did not have to revisit it often."
"However, the area where it should improve is that it gets stuck. It does not have that much amount of data. It does not understand easily, and we have to explain it more."
"It would be better if it were more user-friendly. It would also be better if the implementation were more straightforward."
 

Pricing and Cost Advice

"It's a yearly fee and depends on what you are looking for."
"It is very good. The flexibility to temporarily exceed license limits when setting up new devices is helpful, as it allows us to ensure security before purchasing additional licenses."
"Trend Micro XDR is reasonably priced for its value, comparable to other products like VMware Carbon Black."
"Trend Micro XDR is expensive, and you have to pay for it yearly."
"The price is reasonable. It's not exorbitant. CrowdStrike and other players are on the higher side."
"I find it to be a cost-efficient platform."
"The pricing is fair and not on the higher side."
"When we have a good product such as Trend Vision One, the price is fine."
"Trend Micro XDR is expensive but we got a good deal from Trend Micro."
