Defender CSPM must be enabled because Microsoft Defender for Cloud ' s risk prioritization capability is part of the paid Defender CSPM plan and isn ' t included with Foundational CSPM. Foundational CSPM provides baseline posture-management functions and security recommendations, but recommendations can remain Not evaluated for risk when the resources aren ' t protected by Defender CSPM. Microsoft explicitly identifies Defender CSPM as the prerequisite for recommendation risk prioritization.

Defender CSPM enriches recommendations with contextual risk factors such as Internet exposure, resource sensitivity, exploitability, lateral-movement potential, and business impact . Those factors are used to classify recommendations into risk levels such as Critical, High, Medium, and Low.

Enabling Defender for Servers Plan 2 supplies workload protection capabilities for servers but doesn ' t enable CSPM risk prioritization across Azure and AWS recommendations. Azure Arc onboarding isn ' t required merely to obtain risk levels for an already connected AWS environment. Similarly, assigning the CIS AWS Foundations standard changes which compliance assessments are evaluated; it doesn ' t activate Defender for Cloud ' s recommendation risk-ranking engine.

Therefore, the required change is to upgrade from Foundational CSPM to Defender CSPM .
