What is Cortex, and what tasks do you perform in Cortex?

Cortex is a security analytics platform developed by Palo Alto Networks, designed to provide visibility, detection, and response across an organization’s network, endpoints, and cloud environments. It aggregates logs, network traffic, and threat intelligence from various sources, normalizes the data, and applies machine learning models to identify suspicious activity. In Cortex, you typically perform tasks such as: 1) Ingesting data from firewalls, endpoints, and cloud services; 2) Configuring and tuning detection rules or creating custom rules using the Cortex XDR rule editor; 3) Investigating alerts through the incident view, which provides context, timelines, and forensic data; 4) Automating response actions via playbooks that can isolate devices, block IPs, or trigger ticketing systems; and 5) Generating compliance and forensic reports. The platform also offers a threat intelligence feed that can be integrated into your own security operations center to enhance detection capabilities. Users can also create custom dashboards to visualize threat trends and drill down into specific incidents for deeper forensic analysis.
