What is Cortex XDR ?

Learn about Cortex XDR and the security challenges it addresses.

Cortex XDR is an Extended Detection and Response (XDR) solution that provides comprehensive protection, detection, and response capabilities. It analyzes data from Cortex endpoints and third-party sources to counter evolving cybersecurity threats. Cortex XDR extends beyond traditional endpoint security, providing visibility across network, endpoint, cloud, third-party, and identity sources.

Built on XDR foundations, Cortex XDR is an advanced solution for cloud environments. Explore its key features, the security challenges it addresses, and its data flow below.

Key features

• Comprehensive visibility: Unlike conventional solutions, Cortex XDR ensures complete visibility, not limited to the endpoint. It covers network, cloud, third-party, and identity sources, offering a holistic approach to threat detection.
• Reduced time to detect and respond: Cortex XDR significantly reduces Mean Time to Detect (MTTD) and Mean Time to Respond (MTTR), enhancing overall incident response capabilities.
• Identity-focused threat detection: Out-of-the-box identity-focused threat detection addresses initial access tactics, techniques, and procedures (TTPs). Additional add-ons are available for advanced identity-based threat detection analytics, like insider threats.
• Automation for enhanced efficiency: Cortex XDR incorporates simplified automation actions, streamlining the investigative processes for security analysts and making them more efficient in threat response.
• Proven effectiveness: Cortex XDR boasts impressive results from the MITRE ATT&CK Round 4 Evaluation, achieving a 97% detection rate.
• Data science-driven detections: Leveraging machine learning algorithms, Cortex XDR ensures true data science-driven detections, minimizing noise and improving efficacy, especially for hard-to-detect threats.
• Cloud-powered scalability: Cortex XDR is designed to scale according to enterprise needs, harnessing the power of the cloud without on-premise solution requirements.
• Unified endpoint agent: A unified endpoint agent is included, providing Next-Generation Antivirus (NGAV), Endpoint Detection and Response (EDR), host firewall, device control, disk encryption, and optional add-ons for forensic collection and host insights.

Security challenges addressed by Cortex XDR

Cortex XDR effectively tackles several security challenges faced by organizations today:

• Breaking down silos: By delivering an integrated solution encompassing an endpoint agent, threat detection analytics, automation, identity threat detection, and forensic capabilities, Cortex XDR breaks down security solution silos.
• Continuous threat intelligence integration: Cortex XDR addresses the challenge of outdated and fragmented threat intelligence by continuously integrating curated Unit 42 and Cortex threat research, providing clients with up-to-date insights.
• Balancing threat detection: Cortex XDR mitigates the risk of missing both known and unknown threats, as demonstrated by third-party testing. It maintains a low signal-to-noise ratio, reducing false positives and relieving security analysts from chasing false flags.
• Increased ROI: Cortex XDR offers an increased return on investment (ROI) compared to narrowly focused Endpoint Detection and Response (EDR) solutions and Security Information and Event Management (SIEM) solutions. It provides enhanced detection efficacy while minimizing the management burden on clients.
• Identity-based threat detection: Cortex XDR stands out by addressing the rising concern of identity-based threats, covering insider threats, lateral movement, and anomalous user and entity behavior with the Identity Threat Detection and Response (ITDR) module.

Cortex XDR data flow

The following image describes the data collection, flow, and processing from various sources to Cortex XDR.

Data sources are collected at the bottom of the chain and processed by on-premise servers and engines. Data is initially processed and analyzed using XQL, allowing for queries and analysis. The processed data is integrated with Broker VM, Forensics, and AI and machine learning analytics. This allows Cortex XDR to automate alerts and security.
