Microsoft 365 E3 supports foundational data security and compliance use cases, such as protecting sensitive data, preventing data loss, managing retention requirements, and supporting investigations across Microsoft 365.
Microsoft Purview Suite supports additional data security and compliance use cases, including proactively managing data risk, automating information protection and retention, strengthening records management, supporting more advanced investigations, and gaining deeper visibility into how sensitive data is accessed and used across your organization.
Microsoft Purview Suite also helps organizations better protect sensitive data used by AI applications and Microsoft 365 Copilot, helping reduce the risk of oversharing, data loss, and non-compliant use of data while supporting regulatory requirements.
