What is Extended Detection and Response (XDR)

XDR extends the range of EDR to encompass more deployed security solutions, where the range of EDR improved over the past defenses to help prevent a security breach.

XDR is different from other security solutions in that it centralizes, normalizes, and correlates data from multiple sources, including cloud security, to break down security silos and provide more complete visibility and insights for faster detection.

XDR solutions help reduce false positives and increase response time by collecting and analyzing data from a wide range of sources. This reduces the time security experts might waste on incorrect or excessive notifications. The result of this is improved productivity in security teams and an improved security posture.

XDR goes beyond the capabilities that can be achieved with a combination of security incident and event management solutions. SIEM solutions collect shallow data, while XDR collects deeper data. XDR can provide better context for events thanks to these collection methods. Because the alert sources are native to the XDR solution, the integration and maintenance effort required for monitoring is eliminated

Security analysts need a platform that intelligently brings together all relevant security data to help detect advanced adversaries and sophisticated attacks in real time. As adversaries use more complex attack tactics, techniques, and procedures (TTPs) to successfully circumvent and exploit traditional security infrastructure, organizations are scrambling to secure increasing numbers of vulnerabilities both inside and outside the traditional network perimeter.

Security Operation Center's have been historically stretched for years, and with the recent pandemic, the strain on cybersecurity professionals has been amplified – security professionals are being once again required to do more with the same or fewer resources and with strict budget constraints. Enterprises need unified and proactive security measures to defend the entire landscape of technology assets, spanning legacy endpoints, mobile, and cloud workloads without overburdening security operation center staff.
