Why intelligent detection, automated response and unified security platforms are redefining enterprise cyber defenceArtificial intelligence (AI) has fundamentally changed the cybersecurity landscape. For enterprise security teams, this marks a turning point. This evolution has placed Endpoint Detection and Response (EDR) and Extended Detection and Response (XDR) at the centre of modern enterprise security. How EDR Changes Endpoint SecurityUsing AI, Endpoint Detection and Response extends endpoint protection by continuously collecting telemetry from laptops, desktops, servers and virtual machines. Extended Detection and Response (XDR) addresses this challenge by bringing together telemetry from endpoints, email systems, cloud workloads, identity providers, servers and network infrastructure.
