What is XDR Security? Extended Detection and Response Explained
What is XDR security, and why is it critical to organizations?
XDR unifies detection, investigation, and response across multiple attack surfaces: endpoints, networks, cloud workloads, identity systems, and email. Attackers usually pivot between users, applications, and infrastructure. XDR helps see and identify these multi-vector attacks, accelerating incident detection.

Which security events does XDR monitor across an organization?
Endpoint behaviors (malware execution, privilege escalation), network anomalies (suspicious traffic patterns, lateral movement), cloud security issues (misconfigurations, unauthorized access), identity events (failed logins, account takeovers), and email threats (phishing campaigns, malicious attachments). This builds a complete view of potential attacks across the organization.
