Which solution should be used to track sensitive data across different platforms seamlessly?

The choice of Azure Information Protection as the solution to track sensitive data across different platforms seamlessly is grounded in its capability to classify, label, and protect data based on its sensitivity. Azure Information Protection provides organizations with tools to create policies that define how sensitive information is handled, making it easier to manage data compliance and security across various environments, including on-premises, cloud, and hybrid settings.

This solution integrates deeply with Microsoft 365, allowing for consistent data protection policies across applications and ensuring that data remains secure, regardless of where it resides or is shared. By classifying and labeling sensitive data, organizations can monitor and control access more effectively, thus enhancing data visibility and compliance.

In contrast, while eDiscovery focuses on the identification and management of data during legal proceedings, it does not provide ongoing tracking of sensitive data across platforms. The Microsoft Security Compliance Center is geared more towards compliance management and policy enforcement rather than actively tracking sensitive data. Threat Intelligence centers on understanding and mitigating security threats rather than managing data sensitivity. Thus, Azure Information Protection is the most effective choice for tracking sensitive data across platforms seamlessly.
