ExtraHop is basically an NDR solution - Network Detection and Response. It's a cloud-based offering.
If you want to look at real-time traffic to see what's happening in and out, in terms of malicious traffic throughout the network, you can reveal the suspicious activity using the ExtraHop NDR solution.
It maps the complete network topology so it looks for devices and it builds a complete network, builds a path. It looks for the misconfiguration of the devices and so on. It gives you full 360-degree visibility into your entire infrastructure. For example, it can show you what components are residing, what vulnerabilities it has, and so forth.
