Cortex XDR can communicate with all Traps and Cortex XDR agent releases starting with Traps 5.0. To ensure maximum protection of your endpoints, Palo Alto Networks recommends that you always deploy the latest maintenance version for each agent release.
Critical Environment (CE) versions must be enabled in the Cortex XDR console before use. CE versions are designed for sensitive and highly regulated environments, and do not contain all the updates and content existing in the standard version. Support is provided for CE versions for 24 months.
See Cortex XDR Agent Releases for details of the current agent versions.
