Cortex Data Lake

Basic Information

Palo Alto Networks Cortex Data Lake is a cloud-based service providing centralized log storage and aggregation, forming a core component of the Palo Alto Networks Cortex platform.

• Model: Cloud service, part of the Cortex platform.
• Version: Continuous updates as a cloud-native service.
• Release Date: Publicly introduced around September 2019.
• Minimum Requirements: Requires a valid license for a Palo Alto Networks product utilizing Cortex Data Lake and a Palo Alto user account with appropriate permissions.
• Supported Operating Systems: For data-contributing agents (e.g., Cortex XDR), supported OS include Windows, macOS, Linux, Android, iOS, and VDI workloads.
• Latest Stable Version: Continuously updated cloud service.
• End of Support Date: The core service receives continuous support. Specific Cortex Data Lake SKUs have an End-of-Sale (EoS) date of May 8, 2025, with ongoing support for existing customers who purchased these SKUs. Palo Alto Networks typically provides technical assistance for software products for three years post-EoS, contingent on a valid, continuous support contract.
• End of Life Date: No explicit End-of-Life date for the core service has been announced, though it has been rebranded as Strata Logging Service.
• Auto-update Expiration Date: Not applicable for a cloud service.
• License Type: Licensed separately and is mandatory for using Cortex and its associated applications. Each firewall forwarding logs to the cloud requires a dedicated license.
• Deployment Model: Cloud-based, offering public cloud scalability and agility for log storage and aggregation.

Technical Requirements

Cortex Data Lake operates as a cloud service, abstracting most traditional hardware requirements from the end-user. Technical specifications primarily concern connectivity and integration points.

• RAM/Processor: Not directly applicable to the cloud service itself. Requirements for agents (e.g., Cortex XDR) depend on the endpoint's specific needs.
• Storage: Cloud-based, scalable storage. Default allocation is 80% for logs and data, and 20% for alerts. Storage is provisioned, for example, 1TB for every 200 Cortex XDR Pro endpoints for 30 days.
• Display: Not applicable.
• Ports: For connectivity between Palo Alto Networks firewalls and Cortex Data Lake, TCP ports 444 and 3978 are default for the paloalto-logging-service App-ID. Outbound SSL traffic to the internet is essential. For secure syslog forwarding, port 6514 is the default. Additional App-IDs such as web-browsing, SSL, and OCSP may also be necessary.
• Operating System: For endpoints running Cortex XDR agents that contribute data to Cortex Data Lake, supported operating systems include Windows, macOS, Linux, Android, iOS, and VDI workloads.

Analysis of Technical Requirements

Cortex Data Lake's cloud-native architecture significantly reduces the operational burden on customers by eliminating the need for local compute and storage infrastructure. The primary technical considerations for deployment revolve around ensuring proper network connectivity from Palo Alto Networks devices and compatible third-party integrations. The service itself handles scaling and resource management, allowing organizations to focus on security analytics rather than infrastructure maintenance.

Support & Compatibility

Cortex Data Lake offers extensive support and compatibility within the Palo Alto Networks ecosystem and provides options for integration with third-party tools.

• Latest Version: As a cloud service, it benefits from continuous updates and enhancements.
• OS Support: Data sources like Cortex XDR agents support a wide range of operating systems, including Windows, macOS, Linux, Android, iOS, and VDI workloads.
• End of Support Date: The core service is continuously supported. Specific SKUs have an End-of-Sale date of May 8, 2025, with continued support for existing customers.
• Localization: Hosted in multiple global regions, including the Americas (US), Europe (Netherlands), UK, Singapore, Canada, and Japan, to address data residency and privacy requirements.
• Available Drivers: Not applicable in the traditional sense. Integration relies on APIs, SDKs, and built-in functionalities with Palo Alto Networks products. Log forwarding to third-party security tools is supported via syslog.

Analysis of Overall Support & Compatibility Status

Cortex Data Lake provides robust support and broad compatibility, particularly within the Palo Alto Networks product suite. Its cloud-based nature ensures continuous updates and global availability, catering to diverse geographical and regulatory needs. Compatibility extends to various endpoint operating systems through Cortex XDR agents, and it facilitates integration with other security tools via standard log forwarding mechanisms. This comprehensive approach ensures that the data lake remains a central, accessible repository for security telemetry.

Security Status

Cortex Data Lake is designed with a strong emphasis on security, leveraging cloud best practices and advanced analytics.

• Security Features: Provides secure, resilient, and fault-tolerant cloud-based log storage and aggregation. It employs AI and machine learning for advanced threat detection and analysis.

• Authentication Methods: Customers access applications within the Cortex Hub using single sign-on (SSO), which includes two-factor authentication (2FA). Firewalls authenticate to Cortex Data Lake using device certificates. Token-based authentication is also used for specific log forwarding integrations.
• General Recommendations: Proper configuration of firewalls to permit necessary application traffic (e.g., specific App-IDs and ports) is crucial. Maintaining valid licenses for all connected Palo Alto Networks products is also essential for continuous operation and support.

Analysis on the Overall Security Rating

Cortex Data Lake exhibits a robust security posture. Its foundation in SOC 2 Type II-compliant data centers, coupled with in-transit encryption, multi-factor authentication, and strict access controls, ensures a high level of data protection. The integration of AI and machine learning for threat analysis further enhances its defensive capabilities. While no specific vulnerabilities were found, adherence to recommended configuration practices is vital for maintaining optimal security.
