Cortex XDR, developed by Palo Alto Networks, provides organizations with robust data protection and management capabilities:
Data Ownership:
Data Storage and Retention: Organizations have control over their data storage within the Cortex XDR Data Layer. The platform offers customizable retention periods, allowing businesses to manage their data lifecycle according to their specific requirements.
Data Portability:
Palo Alto Networks outlines specific terms and conditions regarding the renewal and cancellation of contracts for their products, including Cortex XDR. Key aspects include:
Contract Renewal:
Support Contracts: Renewals commence immediately after the expiration of the previous support term, regardless of any gap between the expiration date and the renewal date. This ensures continuous support coverage without penalizing customers for administrative delays.
Licensing Adjustments: Recent updates, effective from June 15, 2023, have separated Cortex Data Lake (CDL) from Cortex XDR and Cortex XSIAM licenses. Customers utilizing CDL for ingesting Palo Alto Networks' network security product logs into Cortex XDR or Cortex XSIAM will maintain their current entitlements throughout the existing contract.
