To discover Personally Identifiable Information (PII) data at risk within Azure resources, what should you recommend?

Recommending Microsoft Defender for Cloud Apps is appropriate for discovering Personally Identifiable Information (PII) data at risk within Azure resources. This service helps organizations to monitor the usage of cloud applications and detect any sensitive information that may be stored or shared inappropriately. Specifically, it offers capabilities such as data loss prevention (DLP) and policy enforcement, which allow organizations to identify and remediate risks to PII data effectively.

Microsoft Defender for Cloud Apps provides deep visibility into cloud activity and incorporates advanced analytics to detect potential threats and sensitive data exposure. This is critical in safeguarding PII data, especially given the various compliance and regulatory requirements organizations must adhere to.

While other options do have their own strengths, they do not focus specifically on the detection and protection of PII data. Azure Monitor is primarily used for tracking the performance and health of Azure resources rather than focusing specifically on the discovery of sensitive data. Azure Data Lake Analytics serves more as a tool for analytical processing, and Azure Information Protection primarily focuses on classifying and protecting data rather than actively discovering it at risk. Therefore, Microsoft Defender for Cloud Apps stands out as the most suitable recommendation for this specific requirement.
