Defining Extended Detection and Response (XDR)
Extended Detection and Response (XDR) is a comprehensive security solution which integrates various security products and data into simplified, unified systems. XDR security combines prevention, detection, investigation, and response to provide a holistic security approach.
How Extended Detection and Response Security Helps?
Extended Detection and Response provide integration and correlation of sensor data collected at multiple points within your enterprise: endpoints, external network boundaries (north/south traffic), internal network boundaries (east/west traffic), cloud workloads, and adaptive decoys. The capabilities of extended detection and response start with the foundation of pervasive visibility into network traffic, endpoint behaviors, and user activity. The visibility coupled with real-time and retrospective threat intelligence, use of analytics/machine-learning, and use of advanced deception leads to detections as well as the ability to investigate and hunt for attackers and insider threats or non-malicious misconfigurations.
Extended Detection and Response security enables alerts to be integrated and correlated, which increases the accuracy and actionability of alerts and can lead to earlier detection of attacks. Open and Active XDR also enables hunting and investigation of incidents based on rich historical data correlated from different data sources in a single-pane-of-glass. The analytics and machine learning capability not only enhance the detections and investigations but allow for the predictive capability to look for abnormalities and anomalies based on specific threat-driven models of deviations from baseline. The pervasive visibility, detections, and ingrained support for response (manual or automated) is the core of this process. What extended detection and response also enables is threat hunting, asset detection, and risk assessment, to allow for the fortification of the preventive posture base.
The “Response” in Extended Detection and Response
The continuous learning and adjustment of security posture towards better prevention and protection is a necessary part of the operations that constantly seek to reduce risk. The response in Extended Detection and Response is the differentiator: it enables responses like updated automatic configuration changes for preventive posture, faster investigations and resolution, automated responses, automatic deception paths, and more. When possible, responses can be automated to improve the efficiency and speed with which security teams identify potential cyber incidents, investigate and validate anomalous activity, and then respond to a cyber incident. This feature of XDR architecture allows for continuous adjustment in security posture to implement policy controls, reduce the attack surface and mitigate impact of attacks – thereby reducing risk to enterprise continuously.

Future of XDR Security Solutions
Here is what the future of extended detection and response solutions could look like:
Integration of AI and ML: Expect increased integration of artificial intelligence (AI) and machine learning (ML) for more advanced threat detection and response capabilities.
Expansion to SMEs: Anticipate wider adoption of XDR solutions by small and medium-sized enterprises (SMEs) seeking comprehensive cybersecurity without the complexity of managing multiple tools.
Regulatory Implications: Watch for regulatory frameworks evolving to accommodate XDR adoption and ensure compliance with data protection and cybersecurity standards.
Hybrid and Multi-Cloud Environments: With the rise of hybrid and multi-cloud environments, XDR solutions will need to adapt to provide seamless security coverage across distributed infrastructures.
Threat Intelligence Sharing: Collaboration and threat intelligence sharing among organizations and XDR vendors may increase to enhance collective defense against sophisticated cyber threats.
Zero Trust Architecture Integration: Integration with zero trust XDR architecture principles to enforce strict access controls and reduce the attack surface, enhancing overall security posture.
User and Entity Behavior Analytics (UEBA) Advancements: UEBA capabilities within XDR solutions may evolve to provide more granular insights into user behavior and insider threats.
Interoperability and Standardization: Expect efforts toward interoperability and standardization among XDR solutions to facilitate seamless integration with existing security ecosystems.

What Influencers are Saying About Extended Detection and Response (XDR)
The definition of XDR is “a security incident detection and response platform that automatically collects and correlates data from multiple security products,” according to Gartner Research, 2021.
Analyst firm ESG considers XDR to be an emerging, commercial version of a security operations and analytics platform architecture (SOAPA) that integrates security control points, automates remediation and IR, and provides advanced analytics for detecting advanced and sophisticated threats. “As it matures, XDR has the potential to improve security efficacy, streamline security operations, and modernize SOCs”.
These definitions lead to a unified, comprehensive yet open cybersecurity platform, which we offer with Fidelis Elevate.
