Engine requirements

Hardware, OS, and required URLs for engines.

You can install engines on all Linux environments. Docker/Podman needs to be installed before installing an engine. If you are using the shell installer for an engine, Docker/Podman is installed automatically.

The Cron package is required to install engines on a Linux machine.

Engine hardware requirements

If your hard drive is partitioned, we recommend a minimum of 50 GB for the /var partition.

Component	Dev Environment Minimum	Production Minimum
CPU	8 CPU cores	16 CPU cores
CPU architecture	x86_64 only	x86_64 only
Memory	16 GB RAM	32 GB RAM
Storage	100 GB	100 GB

Operating system requirements

You can deploy a Cortex Cloud engine on the following operating systems:

Operating System	Supported Versions
Ubuntu	18.04, 20.04, 22.04, 24.04
RHEL	8.x, 9.x, 10.x Includes all minor versions.
Oracle Linux	7.x, 8.9, 9.3, 9.4, 10.1
Amazon Linux	2, Amazon Linux 2023
Rocky Linux	9.5, 9.6

CentOS 8.x reached End of Life (EOL) on December 31, 2021, and is no longer supported as an operating system.

CentOS 7.x reached End of Life (EOL) on June 30, 2024, and is no longer supported as an operating system.

Engine required URLs

You need to allow the following in the URLs for Cortex Cloud engines to operate properly. The URLs are needed to pull container images from public Docker registries.

The endpoint URL is: wss://api-<tenant domain>.xdr.<region>.paloaltonetworks.com/xsoar/d1ws. For example, wss://api-my-tenant.xdr.us.paloaltonetworks.com/xsoar/d1ws

If you have configured a range of Approved IP Ranges under Allowed Sessions on the Security Settings page, the engine must communicate through one of the approved IPs.
