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.

ExtraHop Reveal(x) can improve regarding integration capabilities. For instance, the market is getting really flooded with Microsoft Sentinel, and I know there is an integration possible, but the tools on the market right now indicate that integration should not be a skill from an integrator point of view. It should be quite easy for customers to integrate that solution into SOCs, SIEMs, or any other integration with other tools. There are various integrations from which there's a manual on how to do it, but specifically, the Microsoft portfolio, particularly Sentinel, integration is not yet there. If you score them on a scale of one to ten, ExtraHop scores around a 7.5 to an 8 on an integration basis, but there's actually room for improvement on that side. In the older days, ExtraHop had a license model where you could do all you can eat, so if you had a sensor with 10 gig of capacity, you could use all the entire 10 gig of throughput. They changed that to an asset-based license model, and that's an absolute downside of the solution, where it is harder for smaller companies to acquire the solution itself. That has given us quite some problems in positioning the solution properly within the network, so the licensing model is an absolute downside where they need to improve.
