Open XDR vs Native XDR
Forrester defines open/hybrid XDR as:
An XDR platform that relies on integrations with third parties for the collection of other forms of telemetry and execution of response actions related to that telemetry.
Forrester defines native XDR as:
An XDR suite that integrates with other security tools from their portfolio for the collection of other forms of telemetry and execution of response actions related to that telemetry.
So, let’s put it this way:
Open XDR integrates tools from various vendors, avoiding vendor lock-in and easily fitting into your existing security stack. However, Native XDR ties you to a single vendor, which may reduce flexibility. Open XDR collects security data from multiple sources, whereas Native XDR limits data collection within its own ecosystem, restricting extensibility.
Furthermore, Open XDR offers customizable and automated responses across diverse solutions, while Native XDR relies on pre-configured responses. Also, Open XDR enhances threat hunting by combining intelligence from different sources, but Native XDR is confined to built-in intelligence. One more thing, Open XDR supports scalable cloud-native environments, whereas Native XDR is more tightly coupled with the vendor’s infrastructure, limiting flexibility in hybrid setups.
