XDR is a model that detects attacks across endpoints, networks, software-as-a-service applications, cloud infrastructure, and really any network-addressable resource. Threat hunting is the cybersecurity act of processing information and process-oriented searching through networks, assets, and infrastructure for advanced threats that are evading existing security solutions and defenses. XDR enables teams to prevent known cyberattacks, identify new threats, and strengthen the overall security process by literally finding the attacker hiding in your network.”]
