CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Mid-market and enterprise security teams managing Microsoft 365 collaboration will pick eSHARE to eliminate guest account sprawl without sacrificing external file sharing, a common friction point between security and business units. The tool enforces DLP policies natively within M365 while keeping data resident in your tenant, which maps directly to PR.AA and PR.DS controls under NIST CSF 2.0. Skip this if your organization needs DLP enforcement across non-Microsoft SaaS applications or prioritizes on-premises deployment; eSHARE is built specifically for M365-first shops that want governance without the operational debt of managing external user accounts.
Microsoft Purview Data Loss Prevention
Organizations with Microsoft 365-heavy workflows should pick Microsoft Purview Data Loss Prevention because it requires zero configuration for cloud workloads and catches sensitive data movement across Teams, SharePoint, and OneDrive without additional agents or console sprawl. The integration with Microsoft 365 Copilot means you're protecting data at the point where employees are actually working, not just at the perimeter. Skip this if your critical data lives outside Microsoft's ecosystem or you need network-layer DLP that works equally well on non-Microsoft SaaS applications; Purview's strength is depth within one vendor's stack, not breadth across your entire software inventory.
